Abstract

In this work, we describe our recent work on hybrid Photonic Crystal lasers. By combining high performance gain chips with silicon-based nanostructures, lasers can be created which have properties that cannot be realized using monolithic devices. Laser cavities that are comprised of very different materials can be realized and are suitable for the implementation of cost-effective light sources that exhibit high side-mode suppression ratios and output powers in the milliwatt range. As an illustration of the potential of this architecture, examples are presented that show an athermal wavelength response can be achieved at a range of operating temperatures with the use of active cooling.
