Title: Photodetecting optical element module
Inventor: WATANABE HIROMITSU
IPC: G02B6/42
Filed: 1983-10-11
Abstract: PURPOSE:To suppress influence of reflection at the far end by polishing or cutting an optical fiber diagonally with the optical axis and disposing a photodetecting optical element roughly in parallel with the end face of the optical fiber. CONSTITUTION:The end face 3b of an optical fiber 3 is polished or cut diagonally with the optical axis. Fresnel reflected light is therefore unable to attain backward propagation mode and is radiated as radiation mode to the outside of the fiber 3. On the other hand, the ray emitted from the fiber 3 is subjected to reflection by the window of an avalanche photodiode APD package 7 and an APD chip 6, but the APD package is disposed roughly in parallel with the end face 3b of the optical fiber and therefore the reincidence of the reflected light to the fiber 3 is obviated. The influence of the reflection at the far end is thus suppressed.
