Unlike previous structural compensation studies that were applied on the thermal sensitive materials such as silicon, this work is implemented in tantalum pentoxide (Ta<sub>2</sub>O<sub>5</sub>) platform whose thermo-optic coefficient is low. This allows us to achieve ultra-athermalized filters by combining the structural compensation method and the material's own thermo-optic properties. Two types of devices are proposed: the asymmetric Mach-Zehnder interferometer (AMZI) and the ring-coupled Mach-Zehnder interferometer (RMZI). The temperature-dependent wavelength shift (TDWS) of the AMZI device is only 1.98 pm/K around 1550 nm which is 4.6 times smaller than a regular MZI. The TDWS remains below 2.23 pm/K across a broad bandwidth from 1480 nm to 1580 nm. By breaking the linear dependence between the wavelength shift and the temperature change, the maximum resonance drift can be restricted by using a ring-coupled MZI. Owning to Fano effect, the transmission spectrum of the RMZI device exhibits an oscillating behavior when facing temperature changes. This work proves the effectiveness of structural compensation method on an already low thermo-optic photonic platform, paving the way towards realization of ultra-athermal integrated optical filters in a low-loss and CMOS-compatible platform.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 1","pages":"1-8"},"PeriodicalIF":2.1,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10854680","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361151","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}

Through theoretical analysis, it is demonstrated that incorporating a non-reciprocal phase shifter improves the self-starting capability of the designed fiber laser. Moreover, the phase shifter in the all-PM laser configuration helps boost the repetition rate and further enhances the environmental stability. Numerical simulations are conducted for the proposed fiber laser operating in the normal-dispersion regime to investigate the spectral and temporal characteristics and the build-up dynamics. Experimentally, by manipulating the separation of the intra-cavity grating pair for dispersion compensation, this simple and novel Ytterbium-doped fiber laser delivers ultrashort pulses featuring a pulse duration of 1.81 ps, operating at a repetition rate of 44.4 MHz in the 1030 nm band. The delivered pulses are compressed externally using a grating pair, achieving a minimum pulse duration of 174 fs. We believe the proposed fiber oscillator provides a robust pulsed light source for numerous optical applications such as micromachining or optical frequency comb generation.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10854660","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455354","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, research on coherent detection in underwater wireless optical communication (UWOC) systems is relatively limited. This paper investigates the average bit error rate (BER) performance of coherent UWOC systems employing different phase-shift keying schemes in the presence of phase errors. The underwater turbulent channel is characterized by the mixture exponential-generalized gamma distribution, taking into account the impact of pointing errors as well. Phase errors are modeled by a Gaussian distribution. Specifically, we first derive the average BER expressions for <inline-formula><tex-math>$M$</tex-math></inline-formula>-ary phase-shift keying (MPSK) under ideal carrier phase estimation. Then, we derive the exact average BER expressions for binary phase-shift keying and quadrature phase-shift keying, as well as tight approximations for MPSK, considering the influence of phase errors. Additionally, we provide asymptotic BER expressions in the high signal-to-noise ratio region and the BER floor expression. Finally, these expressions are validated through Monte Carlo simulations.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 1","pages":"1-9"},"PeriodicalIF":2.1,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10854612","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361153","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}

A single-focus lens is given to demonstrate the validity of the proposed fringe deflection algorithm. Then the optical parameters calculation models of free-form lens, such as progressive lens, is presented and the detection results are given. Moreover, the results of the proposed fringe deflection algorithm are in close agreement with those obtained from simulations and the FFV interferometer. The error of free-form lens measured in this paper is less than 0.02D.

In particular, tunable inversion probability sequence (p-tunable sequence) phase modulation effectively optimizes the spectral envelope, improving the SBS threshold in a monolithic narrow linewidth fiber amplifier. This paper theoretically and experimentally investigates the SBS suppression capability of p-tunable phase modulation. Firstly, we introduce a theoretical model to illustrate, for the first time, the temporal and spectral properties of light waves that have been phase-modulated by a p-tunable sequence. An optimization scheme for parameter selection of p-tunable sequence phase modulation is established by calculating the SBS threshold. Meanwhile, we establish a three-stage fiber amplifier system with p-tunable phase modulation to verify our theory. The output power is 2390 W with an FWHM optical linewidth of 10 GHz. Compared to the pseudo-random binary sequence (PRBS) case, this scheme increases the output power by 700 W at 10 GHz FWHM optical linewidth.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-12"},"PeriodicalIF":2.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10850764","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143521417","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}

This article constructs a processing prediction model for large-diameter ring pendulum double-sided polishing equipment. Based on this, a simulation of the theoretical removal amount distribution of ring-pendulum double sided polishing was conducted to ascertain the relationship between various process parameters and their impact on the surface removal amount distribution of the component. Based on the obtained relationship, a decision support system for the process parameters of ring-pendulum double sided polishing was developed, which achieved the deterministic removal of rings in medium and large aperture planar optical components and reduced the dependence of ring pendulum double-sided polishing on the personal experience of process decision-makers. After experimental verification, the characteristics of the simulation results of the processing prediction model were consistent with the actual processing results. The developed process parameter decision assistance system was used to make process parameter decisions for two 430 * 430 mm fused quartz components, achieving the removal of the target ring of the components.
