Abstract

Unlike InP-based systems for long-distance communication applications, GaAs-based optoelectronic systems mostly for local-area network, optical interconnection or optical computing are very cost-sensitive because often these optoelectronic devices constitute most of cost for these applications and fewer users share the cost. Thus besides technical issues (e.g., uniformity of devices, stabilization of emission wavelength, reliability at high power and high temperature operation), the processing cost should be addressed in the selection of materials and fabrication methods. We discuss a number of major advantages of Al-free InGaAsP/GaAs lasers for these applications, such as no coating-requirement, low cost, high long-term reliability, high performance. We discuss recent preliminary results of Al-free lasers as a first step toward these optoelectronic applications.
