Coherent Detection for 1550 nm, 5 Gbit/s VCSEL Based 40 km Bidirectional PON Transmission
Coherent Detection VCSEL Based Bidirectional PON Transmission
2015/5/22
Coherent detection of directly modulated 1550nm VCSELs in 5Gbit/s bidi-rectional 40km SSMF PON-links is presented. Receiver sensitivity of –37.3dBm after transmission is achieved with 30dB system marg...
High-Performance 850 nm VCSEL and Photodetector Arrays for 25 Gb/s Parallel Optical Interconnects
Fiber optics components
2015/6/9
We design, fabricate and demonstrate 850 nm VCSEL and PD arrays which operate at 25 Gb/s per channel, up to 600 Gb/s with 24 channels, for low-power parallel optical module applications. We also repor...
根据增益波导垂直腔面发射激光器直接耦合的准三维理论模型，通过有限差分法对注入电流密度、载流子浓度、光场和热场分布方程求自洽解.研究了垂直腔面发射激光器的电、热和光波导特性，同时提出了一种具有双氧化限制层的增益波导垂直腔面发射激光器结构，并通过对比研究了N-型分布布喇格反射镜和双氧化限制层对增益波导垂直腔面发射激光器特性的影响.计算结果表明，如果忽略N-型分布布喇格反射镜的影响将与实际的垂直腔面发射...
