Abstract
We developed a hybrid integrated optical module for 1.3/1.55-mum wavelength -division multiplexing (WDM) full-duplex operation. The optical circuit was designed to suppress the optical and electrical crosstalk using a waveleng th division multiplexing filter. And an optical crosstalk of -43 dB and an electrical crosstalk of -105 dB were achieved with a separation between the transmitter laser diode and the receiver photodiode of more than 9 mm, We used the optical circuit design to fabricate an optical module with a bare chip preamplifier in a package. This module exhibited a full duplex operati on of 156 Mbit/s with a minimum sensitivity of -35.2 dBm at a bit error rat e of 10(-10).
