The scheme exploits coherent four-wave mixing (FWM) in a dual-pump highly nonlinear medium to generate a phase-conjugated idler, which coherently combines with the input QPSK signal to extract both in-phase and quadrature BPSK components. A half-bit-period temporal staggering repacks these components into a single TI-BPSK stream, achieving optical-domain baud rate doubling without digital signal processing (DSP). Numerical simulations using a vectorial split-step Fourier method (SSFM) capture nonlinear, dispersive, and polarization-dependent dynamics, while analytical formulations of PSA gain, phase mismatch, OSNR evolution, bit-error rate (BER), and error vector magnitude (EVM) provide independent validation. Monte Carlo analyses further establish robustness to birefringence and dispersion fluctuations. Results confirm high-fidelity TI-BPSK generation with BER and EVM performance consistent with analytical bounds. Compared with interferometer or DSP-based de-aggregation, the proposed single-stage optical approach delivers energy efficiency, scalability, and resilience, positioning it as a promising solution for elastic and software-defined optical networks (SDONs).","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"62 2","pages":"1-12"},"PeriodicalIF":2.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147665395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It incorporates a sublayer of microspheres for retroreflection and multi-quantum-well structure for modulation over the optical communication C-band (1530–1565 nm) when driven by digital voltages (0–5 V). Our theoretical analyses show that LaSFN9 and BaTiO3 microspheres, with refractive indices of 1.8 and 2.0, respectively, give optimal retroreflection for shorter and longer link lengths, respectively; our experimental analyses reveal that our AlGaInAs-based modulator imparts sufficiently deep modulation over the C-band. This lets our integrated retro-modulator surfaces with LaSFN9 or BaTiO3 microspheres function with fields-of-view of 10.8° or 9.4°, respectively, and modulation depths of 3.4% or 5.3%, respectively (giving extinction ratios of 0.93 or 0.89, respectively). Our characterizations of error performance through links with weak, moderate, and strong turbulence then show error vector magnitudes of 3.7%, 9.2%, and 24%, respectively, with bit error rates below <inline-formula> <tex-math>$10^{-3}$ </tex-math></inline-formula>, below <inline-formula> <tex-math>$10^{-3}$ </tex-math></inline-formula>, and equal to 0.0183, respectively.

In many applications, an OAM beam with coverage over a specific frequency band is required, and supercontinuum (SC) generation presents a viable solution to provide a broadband OAM source. The launch of a short pulse into a specially designed fiber with flat dispersion across a broad wavelength range leads to broadband SC generation through nonlinear spectral broadening during propagation. In this study, we propose a dual concentric ring fiber design that achieves a flat and near-zero dispersion profile over a wavelength range extending up to 3435 nm, featuring four zero-dispersion wavelengths for the OAM mode. The zero-dispersion wavelengths can be precisely tuned by adjusting the structural parameters and the germanium doping concentration in the silica-based fiber. The spectral broadening performance, in terms of flatness and bandwidth, is evaluated under various input pulse and fiber conditions. Simulation results indicate that the OAM3,1 mode SC can span nearly three octaves at the -40 dB level when pumped with a 50-fs, 600-kW Gaussian pulse centered at 1500 nm. With further optimization of the fiber structure for different OAM modes, the generated SC extends beyond 2.82 octaves. Additionally, the effects of different shape factors on the SC characteristics are systematically compared.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"62 2","pages":"1-8"},"PeriodicalIF":2.1,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These charged acceptor-type defects function as negatively charged centers that capture the injected holes and enhance nonradiative recombination at the cavity facets. This significantly enhances the self-heating effect and causes thermally induced facet degradation. To address this challenge, we propose introducing a high-k HfO2 buried field-plate termination. The high-k HfO2 buried field-plate enables the stronger electric field magnitude in the GaN region underneath the high-k HfO2 region, which generates the valence band barrier height and achieves hole confinement. With the developed physical models on the facet, we find that the proposed structure can suppress facet degradation by reducing surface recombination and decreasing the facet temperature. As a result, our design delays the onset of nonradiative-recombination-induced heat in the facet region and enhances the COMD threshold.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"62 2","pages":"1-8"},"PeriodicalIF":2.1,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147299632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
