By leveraging the multi-mode characteristics of a Fabry–Perot (FP) laser, the system maps binary information onto chaotic attractors of different longitudinal modes, enabling parallel multi-channel information keying. Combined with wavelength division multiplexing (WDM) technology, the transmission rate is significantly enhanced. A dual encryption mechanism is implemented by firstly performing chaos shift keying encryption on each channel independently, followed by collective encryption of the multiplexed signal through chaotic phase modulation, effectively concealing wavelength information and improving anti-eavesdropping capability. Simulation results demonstrate that the system achieves secure transmission at an aggregate rate of 30 Gb/s over a span of 80 km single-mode fiber, exhibits strong resistance to return map attacks, and possesses excellent security and practicality.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 2","pages":"1-8"},"PeriodicalIF":2.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11455179","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148508869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a multi-objective parameter extraction method based on the deep neural network (DNN), that can not only efficiently and accurately extract the realistic parameters of DFB lasers but also resolve coupling issues among parameters. Two forward DNN models are trained using traveling wave model (TWM) and transfer matrix method (TMM), respectively, to predict the light-current (L-I) characteristics, amplitude modulation (AM) response, and spectrum of DFB lasers. After fabricating and measuring lasers, the extracted parameters are iteratively optimized against the experimentally measured results utilizing the well-performing forward models and differential evolution algorithm. Through Pareto sorting, an optimal parameter set is extracted, which can accurately reproduce all target characteristics (the LI curve, AM response, and spectrum) at the same time. The proposed method greatly reduces the computational complexity and avoids the time-consuming situation of traditional TWM and TMM calculations. Using the extracted parameters, the large-signal modulation is theoretically calculated. And it fits very well with the measured results, which verifies the practicality and reliability of the proposed method.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 2","pages":"1-8"},"PeriodicalIF":2.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11455157","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148504403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two new designs are proposed, low-duty-cycle and focusing HCG. These designs are verified using FDTD 3D simulations and then fabricated. From the characterization, the best result was obtained with a low-duty-cycle design, that achieved a maximum tuning range of 67.8 nm and an average tuning range of 55.8 nm surpassing the standard design where we obtained 62.2 nm and 50.2 nm respectively. Furthermore, the new designs displayed better performance in the maximum output power and a better far-field profile compared to the standard design, indicatingimproved light extraction efficiency.

The use of optical and electrical filtering by means of a fiber Bragg grating (FBG) and an electrical bandpass filter (EBPF), respectively, permits to mitigate undesirable optical and electrical signal components and reduce fiber dispersion effects. For the proof-of-concept demonstration, a standard-compliant 5G new radio 64-QAM OFDM signal at different intermediate frequencies was successfully transmitted over a fiber-wireless system in the W band (75–110 GHz). The system characterization under different hardware configurations was comprehensively analyzed to give insights for the system design under different operation conditions.

The DC-ARF consists of six thin-walled, azimuthally offset inner tubes enclosed within a thicker outer cladding tube, which is further connected to silica jacket through a single node. Asymmetric offset arrangement of inner cladding tubes generates two enlarged gaps based on mode field distribution of LP11-like mode, ensuring high-order mode (HOM) suppression. Numerical simulations show that light guidance is achieved through leakage from the larger gaps followed by anti-resonant reflection back into the core. And wavelength disparity between fundamental mode and HOMs provides inherent mechanism for preferential HOM suppression. Through structural optimization, significantly improved mode purity is achieved. The fabricated DC-ARF features two large azimuthal gaps of 70° and operates at a wavelength of 1.06 μm. Experimental results confirm that only the fundamental mode remains when the fiber length exceeds 0.5 m. Furthermore, a 1-m-long DC-ARF improves the input beam quality by approximately 40%, demonstrating its mode tailoring capability. Our work offers valuable guidance for mode tailoring, and the proposed DC-ARF has great potential in single-mode laser transmission, biomedical systems, and optical communications.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 2","pages":"1-7"},"PeriodicalIF":2.4,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11419729","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147440498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the crosstalk, filtering, and mixing effects arising from the interaction between frequency offset (FO) and transceiver impairments significantly degrade the FO tolerance of the WL-MIMO equalizer, limiting its applicability in Nyquist WDM systems. In this paper, we introduce an FO pre-compensation 8 × 2 WL-MIMO equalizer. By integrating a specially designed single-branch FO compensation structure with an 8 × 2 WL-MIMO equalizer based on the digital phase-locked loop least mean square algorithm, the proposed method achieves FO-insensitive transceiver impairment compensation with nearly unchanged computational complexity. Simulations of a Nyquist WDM system show that the proposed scheme achieves an FO tolerance exceeding 5 GHz. Moreover, a 32 GBaud dual-polarization 64 quadrature amplitude modulation signals transmission experiment over 75 km standard single-mode fiber further confirms that, while maintaining stable transceiver impairment compensation, the proposed scheme significantly extends the FO tolerance from 200 MHz to beyond 2 GHz compared with the conventional 8 × 2 WL-MIMO equalizer.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 2","pages":"1-8"},"PeriodicalIF":2.4,"publicationDate":"2026-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11410515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
