Abstract

Photonic integration can extend all the benefits of individual semiconductor devices to a wide variety of more complex and otherwise uneconomical applications. In the mid-infrared, quantum cascade lasers (QCLs) based on InP have long since been established as the predominant light source, due to their large spectral range of operation as well as their high output power. As a result, the natural choice for a platform of integration would be the one based on InP. One exciting field for applying mid-infrared photonic integration is multi-species gas sensing.
