Laser diode array module for parallel optical interconnection

An 8-channel optical interconnection laser diode (LD) array module, which is a receptacle type with an multi-fibre push-on (MPO) adapter, was successfully fabricated. In consequence of adapting a receptacle type, mounting of this module on a board was facilitated. Furthermore reliability of this LD array module is guaranteed because the LD array is hermetically sealed. A variation of optical output power in each channel was obtained within 0.3 dB, and a fluctuation of coupling losses caused by reconnecting was obtained at less than 0.5 dB, respectively. Digital output at 300 Mbit/s/ch was demonstrated.
