Abstract

Photonic integration is required before mass deployment of advanced optoelectronic systems is possible. Several viable technologies for fabrication of monolithic photonic integrated circuits (PICs) have been developed. InP-based PICs have been deployed in telecommunication systems, but the main focus here is GaAs-based PICs capable of delivering energy under precision control to precise locations. Integration technology based on quantum well intermixing is described in the context of device performance and yield. Individually addressable arrays of lasers are described operating in the wavelength range 800 to 980 nm, delivering up to 500 mW per element, and with up to 100 monolithic elements. By placing monolithic arrays side by side powers can be scaled further, with current modules delivering 150 W in continuous wave operation.
