A monolithic four-channel optical transmitter at 0.8 μm wavelength has been fabricated. This has been achieved by using AlGaAs/GaAs optoelectronic integrated circuit (OEIC) approach. The OEIC chip contains four transmitter channels and each channel is composed of a graded-index waveguide separate-confinement heterostructure single quantum well laser, a monitor photodiode, and a laser driver circuit. The characteristics have been shown to be very uniform over four channels and pulse modulation responses over 1 Gb/s have been achieved.
