光通信用高速长波长APD结构优化与最佳光倍增

Structural optimization and optimal photomultiplication factors for the high sp eed, long wavelength APDs used in optical communication systems

分析、比较了几种台面和平面长波长 APD在结构、技术指标和可靠性等方面的优缺点 ;指出了长波长 APD的一些物理限制和目前工艺水平下的择优结构 ;从实践和理论上讨论了 APD的最大倍增和最佳光接收机灵敏度 .

This paper analyses and compares the advantagies and dis advantagies in structure, specifications and reliability for some types of mesa and planar, long wavelength APDs, presents some physical limitations and optimum structures for the long wavelength APDs under present technology conditions. Th e greatest photomultiplication and the optimum optical receiver sensitivity of the APDs are also discussed practically and theoretically.
