A Back-illuminated pin-photodiode has a monolithic lens optimized for SM fiber at the InP substrate and achieves high responsivity, wide-tolerance and high-speed. The component of a high-speed and low-noise preamplifier and the photodiode obtains high sensitivity and a stable operation. The high performance butterfly package was developed for high-speed operation, small dimension and low cost. The module is applicable for 1.31m/1.55m optical fiber communication systems for OC-192/STM64, typically showing a high sensitivity of -19dBm.
