Such frequency modulation dynamically changes the detuning between the target slave laser and the injecting master laser. A comparison is also made of the behaviour of regular semiconductor lasers when subject to frequency-modulated optical injection. It is shown that both quantitatively and qualitatively different dynamical behaviours arise as the depth and frequency of the frequency modulation are changed. Such differences are revealed in the detail of the laser power spectra. A comparison is also made of the response of regular semiconductor lasers to frequency modulated optical injection where a range of behaviours is again made apparent via the power spectra. It is indicated that there is significant scope for further investigation of the phenomena revealed here.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 4","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144725208","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}

Among several variants, the optical-loop-based CIM, which utilizes optical pulses with binary phases circulating in a loop equipped with a pulse-pumped phase-sensitive amplifier (PSA) and a measurement feedback circuit, has experimentally demonstrated high performance in terms of the number of pulses and connectivity. This study numerically investigates the dependence of its calculation performance on operating conditions such as the noise level, coupling strength between pulses, and PSA pump increment rate. The CIM solving Max-Cut problems is simulated using a difference equation based on a traveling-wave model under various operating conditions. The results indicate that noise is not a critical factor, there is an optimal condition for the coupling strength, depending on the graph structure, and slower pump-increment rate leads to higher scores. Under optimal conditions, the simulation produces better calculation results than those previously reported in an experimental study.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 4","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144725206","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}

Optical negative feedback (ONF) induced by reflection of light from a Fabry-Perot (FP) resonator reduces linewidth of a distributed Bragg reflector (DBR) laser by 1/14 compared to that of a free-running DBR laser. The measured reflectivity of the fabricated ONF laser is compared to reflectivity simulated with an effective reflectivity model. It is demonstrated that control of the feedback phase is necessary to reduce linewidth by exploiting optical negative feedback. Linewidth is expected to be further reduced by using an FP resonator with a higher quality factor. It is also demonstrated that ONF lasers are compatible with fabrication in the InP foundry platform.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"61 4","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144725202","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}

However, current solutions to integrated optical phase modulators at visible wavelengths face challenges such as high insertion losses, large footprints, low bandwidth, and high-power consumption. In this work, we introduce a graphene-based integrated optical phase modulator designed for operation at 488 nm, implemented on silicon nitride photonic integrated circuits. This design aligns seamlessly with standard silicon photonic processes. The 3-dB bandwidth of the integrated optical phase modulator ranges from 3 GHz to 148 GHz depending on design and fabrication conditions, and a 74 GHz 3-dB bandwidth is considered achievable based on previously published results. Meanwhile, a modulation efficiency (quantified by the product of the <inline-formula> <tex-math>$pi $ </tex-math></inline-formula>-phase shift voltage and length, <inline-formula> <tex-math>$boldsymbol {V_{mathrm {pi }}L}$ </tex-math></inline-formula>) of 0.13 V<inline-formula> <tex-math>$cdot $ </tex-math></inline-formula>cm could be attained. Moreover, the modulator is capable of operating across the entire visible wavelength range.
