1.1 Gb/s pseudorandom pulse-code modulation of 1.27 μm wavelength c.w. InGaAsP/InP d.h. lasers

Abstract
Pulse-code modulation of InGaAsP/InP d.h. injection lasers at a 1.1. Gb/s rate in a room-temperature environment has been demonstrated. The operating wavelength was 1.27 μm. Fabrication and characteristics of the lasers, design of the 1.1 Gb/s circuitry, and performance of the experimental transmitter are described briefly.
