Abstract
High-speed optoelectronic hybrid-integrated transmitter module has been developed using a silica-based planar lightwave circuit (PLC) platform on which a laser diode (LD) array and a two-channel LD driver IC were integrated. Heat absorption through a highly thermal conductive silicon terrace kept the average output power constant to within 5% during IC operation. Bit-error-rate (BER) measurement showed that this module operated successfully with a 9-Gb/s nonreturn-to-zero (NRZ) signal. This indicates that the PLC platform does not have any adverse effect on the frequency bandwidth of the integrated chips. This approach, using the PLC platform for integrating optoelectronic devices and electronic ICs, will lead to the development of a high-speed optical multichip module for optical signal processing.
