An InP pin-photodiode with monolithically integrated resistors and capacitors is utilized to spontaneously achieve excellent noise immunity with a large dynamic range. A high-speed and low-noise built-in GaAs preamplifier obtain high sensitivity and a stable operation. The high performance butterfly package was developed for a high-speed operation, small dimension, and low cost. Furthermore, two optical functions, bending an optical axis and focusing, can be successfully achieved by only one optical component without lenses. This originally developed optical component technology without lenses achieved lower optical losses at a low cost. The F0849956F is applicable for 1.3 m/1.55 m optical fiber communication systems for OC-192/STM-64, typically showing a high sensitivity of -18 dBm.
