An optical module for use in both 1.3- mu m signal transmitting/receiving and 1.3/1.5- mu m signal multi/demultiplexing was developed by assembling a silica-based planar lightwave circuit composed of wavelength division multiplexing (WDM) and optical coupler circuits, a miniature laser diode (LD) submodule, and a photodiode (PD) submodule. The module exhibits 0-dBm optical output at 32-mA driving current and a responsivity of 0.3 A/W for a 1.3- mu m band, and an insertion loss of 0.9-2.0 dB for a 1.5- mu m band.<>
