Paper Abstract

Lateral current injection lasers are ideal sources for monolithic OEICs. They are grown on semi-insulating substrate for low parasitic conduction and delays; consist predominantly of undoped layers for ease of inter-device isolation and low- free carrier induced absorption and chirping; have both electrodes on the surface and can be readily integrated with other devices using a planar process with a minimum number of steps. Vertical injection lasers, though their performance as discrete devices is greatly perfected and presently enjoying the monopoly position with no competition in sight, are largely laterally invariant and do not generally possess these characteristics. On the other hand, lateral current injection lasers remain to be studied systematically and greatly improved to become a serious contender in the field. This article reviews the attempts, of ours and others to date, and outlines the important issues concerning LCI's unique internal device operation mechanisms and device design. It also aims to draw attention to the fact that ease of integration is only one feature of the great potential of the lateral injection lasers. This potential comes from the release of an additional degree of freedom, and offer many exciting and unique opportunities for developing new devices and new functionalities.
