Abstract
A four-channel DFB laser transmitter OEIC incorporating JFET drive ele ctronics on an InP substrate is described. Fully functional circuits h ave been fabricated with single-mode lasers operating in the 1545-1560 nm window, with wavelength separation between adjacent channels of ap proximately 0.8 nm. Laser modulation at 155 Mbit/s was achieved. To th e authors knowledge this is the first demonstration of a monolithic fo ur-channel transmitter OEIC based on JFETs and DFB lasers.
