An optimization strategy of waveguide-based multi-quantum well (MQW) BPDs, operating at 1550 nm is demonstrated on a generic InP platform. Design parameters of BPD are optimized towards achieving the highest bandwidth for a responsivity through an algorithm based on Particle Swarm Optimization (PSO). We do so by establishing an equivalent circuit model of BPD and analyzing its opto-electronic transfer function through numerical modelling. We address the major bottlenecks of high-speed BPDs: transit time of generated carriers and RC loading in our model. The algorithm is able to provide multiple combinations of design parameters with the same output characteristics. The design methodology to integrate laser with optimized BPD is presented to successfully implement a coherent receiver.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 3","pages":"1-12"},"PeriodicalIF":2.5,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10379816","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139946259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GaN p-i-n LED structures are implanted with manganese to form a ferromagnetic phase and illuminated with resonant photons across the GaN bandgap.

Subsequent illumination below the GaN:Mn bandgap is found to remove the photo-enhancement of magnetism and fully demagnetize the material. The optically-driven process confirms that photon absorption drives hole-media induced ferromagnetic changes to the top layer in GaN:Mn structures. A modified p-i-n structure is designed that situates a two-dimensional hole gas (2DHG) beneath the magnetic layer for improvement of the hole injection effect. The mid-gap state formed by the implanted manganese in GaN:Mn is simulated for two-photon electromagnetic induced transparency that can control the absorption of the top layer and moderate the hole injection. The design of GaN:Mn p-i-n structures is explored for spin-photon mapping of states for long-term storage in memory systems.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 1","pages":"1-12"},"PeriodicalIF":2.5,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139399819","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}

The simulation results are compared with experimental data from the literature to demonstrate the model accuracy and underline the impact of npp Auger recombination and intervalence band absorption on the high room-temperature characteristic temperature of p-doped lasers. Applying this model to membrane lasers featuring high optical confinement factors in small active regions due to the use of thin III-V stacks as compared to conventional lasers, we demonstrate the potential of such lasers for short-distance optical interconnects as high temperature (110 °C) operation is predicted for an optimized design, with submilliamp threshold up to 60 °C.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 1","pages":"1-9"},"PeriodicalIF":2.5,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138822194","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}
