Optical whispering gallery mode (WGM) resonators, known for their ultrahigh quality factors and sensitivity to weak perturbations, inherently support multiple mechanical modes and can be used for multi-channel parallel magnetic communication. However, the mechanical resonance modes are sparsely distributed and exhibit inconsistent response strengths, which limits the number and reliability of available communication channels. Therefore, we introduce a magneto- elastic heterostructured resonator integrating Terfenol-D to enhance magnetoelastic coupling, which significantly augments the density of frequency domain communication channels with nearly uniform response. Experimental results demonstrate the use of 10 parallel mechanical subcarriers to achieve a total data rate of 12.5 kbps—an order-of-magnitude improvement over single channel designs—with potential for further scalability. By employing multimodal resonance multiplexing with a microcavity-based sensor, our work establishes a new paradigm for high-capacity, short-range magnetic communication in complex environments.","PeriodicalId":16144,"journal":{"name":"Journal of Lightwave Technology","volume":"43 20","pages":"9742-9750"},"PeriodicalIF":4.8,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The single mode fiber - dispersion compensated fiber - single mode fiber (SDS) sensor achieves a temperature sensitivity of 47.35 pm/°C in the range of 30–110 °C, which is four times greater than that of a typical fiber Bragg grating (10 pm/°C). The single mode fiber - dispersion compensated fiber (SD) sensor based on the Michelson interference (MI) principle is fabricated by splicing a DCF at the end of a single mode fiber (SMF), which effectively suppresses multimode interference and attenuates interference peaks using Fresnel reflection. The sensitivities of the SD fiber sensors with DCF lengths of 7 mm, 8 mm and 9 mm are 62.38 pm/°C, 53.45 pm/°C and 51.25 pm/°C, respectively, in the temperature range of 30–200 °C, and the free spectral range (FSR) of the interference spectra decreases with increasing DCF length. After high-temperature annealing of the fiber microstructures, the internal stress of the DCF can be effectively released, which improves the dispersion compensation performance and reduces the transmission loss. We select SD fiber sensors with a DCF length of 7 mm for high-temperature annealing and then repeat the high-temperature experiments over a wide range of 30–800 °C, and the interference spectra all show consistent redshifts. The temperature sensitivity in the range of 500–800 °C is as high as 106 pm/°C. The refractive index difference between the DCF core and cladding changes as the temperature increases from 800–1000 °C, and the redshift trend of the interference spectrum with increasing temperature is reversed to a blueshift at 920 °C. This sensor, characterized by a wide temperature range, adjustable sensitivity and good repeatability and stability in high-temperature environments, has significant application potential in industrial production.","PeriodicalId":16144,"journal":{"name":"Journal of Lightwave Technology","volume":"43 20","pages":"9751-9760"},"PeriodicalIF":4.8,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extensive spectrum resources and complex physical layer interactions in MB systems present challenges for traditional resource management solutions that are evaluated only for the C-band. Effective algorithms tailored for MB optical networks are needed to enable optical networks to provision services efficiently, thereby reducing service blocking and improving network throughput. In this study, we propose a deep reinforcement learning (DRL)-assisted framework for dynamic service provisioning in MB elastic optical networks. The proposed DRL framework aims to minimize long-term bit-rate blocking and includes several innovations. First, an accurate quality of transmission estimation model is employed to profile the performance of the supported modulation formats for each channel on pre-computed routes. Within the DRL agent design, a novel state representation incorporating both route-level and band-level features is designed to enhance the DRL agent's ability to perceive the network conditions. Moreover, a new reward function has been developed to enhance performance and accelerate convergence. Simulations are performed using a number of L+C+S MB systems with and without traffic grooming support. The results indicate that the proposed DRL-assisted framework can reduce bit rate blocking by an average of 35% to 85% compared to the existing heuristic methods from the literature while maintaining an appropriate inference time.","PeriodicalId":16144,"journal":{"name":"Journal of Lightwave Technology","volume":"43 19","pages":"9090-9101"},"PeriodicalIF":4.8,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These pulses are processed through vertical cavity surface-emitting lasers with an embedded saturable absorber (VCSELs-SA), effectively emulating biological synaptic transmission for classification tasks.

In such applications, silicon photonic (SiP) self-coherent detection emerges as an attractive solution. As an advanced SiP device, microring resonator (MRR) also gains a significant attention due to its design flexibility and wavelength selectivity, heightening its application potential in optical communication systems such as self-coherent detection systems. In this work, we demonstrate a silicon photonic tunable ultra-narrow-bandwidth (UNB) coupled resonator optical waveguide (CROW) filer based on second-order add-drop microring resonators. Under the minimal insertion loss condition for the drop port, we optimize the coupling coefficients to achieve an UNB CROW filter with a low insertion loss. Significantly, the CROW filter has been demonstrated with a 1.26-GHz 3-dB bandwidth, 4.62-GHz 20-dB bandwidth, approximately 4-dB insertion loss and 60-dB extinction ratio (ER) based on a 1-μm-wide ridge waveguide which has a weaker sidewall scattering compared with a strip waveguide. Due to its ultra-narrow bandwidth and high ER, it can provide a good rejection of signal components for a self-coherent signal, thereby a pure optical carrier can be extracted to realize coherent detection without an additional local oscillator (LO). Applied in the carrier-extracted self-coherent (CESC) detection system, achieving a 168.3 Gb/s transmission rate over 100-km standard single mode fiber (SSMF), the performance of this CROW filter is well verified.","PeriodicalId":16144,"journal":{"name":"Journal of Lightwave Technology","volume":"43 19","pages":"9318-9324"},"PeriodicalIF":4.8,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145061842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimization of the intracavity polarization state and intracavity nonlinear effects enables the generation of CVBs with an average power of 500 mW and the corresponding pulse width compressed to 251 fs. To our knowledge, this is the first demonstration of high average power, femtosecond CVBs generation in an all-fiber MO. Further optimization in pump power and gain management allows for the generation of harmonic CVBs up to the ninth-order, corresponding to a repetition rate of approximately 210 MHz.

The optical sideband of the signal under test (SUT) is simultaneously mixed with the multiple frequency-sweeping optical sidebands generated from a semiconductor laser working in the period-one state. Multiple FTTM curves are achieved in a single channel due to the use of multiple frequency-sweeping optical sidebands and the square-law detection feature of the photodetector. The mixing products then pass through an electrical bandpass filter and an envelope detector to obtain electrical pulses at low speed. Multiple FTTM curves are exploited jointly to map the frequency of the SUT to the number and time locations of the generated electrical pulses, which can be captured with a low sampling rate. In this way, without introducing complex structures, the measurement bandwidth of the system can be effectively increased while guaranteeing the time and frequency resolutions. In a proof-of-concept experiment, four FTTM curves are realized by using the −1st and the −2nd-order frequency-sweeping optical sidebands. The instantaneous measurement bandwidth is extended to 39.8 GHz, with the working frequency range from 7.6 to 47.4 GHz and a root-mean-square error of 35 MHz.
