Abstract

1.3-μm uncooled cylindrical and receptable lasers are on the threshold of large-scale implementation for fiber-in-the-loop application. This demands a high-performance chip that can operate over a wide temperature range, can achieve sufficient fiber-coupled power by using low-cost packaging and optics, and can be manufactured at low cost. We achieved a solution to this challenge by using a compressively strained deep-quantum-well AlGaInAs structure combined with a ridge-waveguide (RWG) chip.
