Abstract: Building blocks are provided for on-chip chemical sensors and other highly-compact photonic integrated circuits combining interband or quantum cascade lasers and detectors with passive waveguides and other components integrated on a III-V or silicon. A MWIR or LWIR laser source is evanescently coupled into a passive extended or resonant-cavity waveguide that provides evanescent coupling to a sample gas (or liquid) for spectroscopic chemical sensing. In the case of an ICL, the uppermost layer of this passive waveguide has a relatively high index of refraction that enables it to form the core of the waveguide, while the ambient air, consisting of the sample gas, functions as the top cladding layer. A fraction of the propagating light beam is absorbed by the sample gas if it contains a chemical species having a fingerprint absorption feature within the spectral linewidth of the laser emission.

Abstract: A waveguide and methods for manufacture can include a silicon wafer and a silicon substrate on the wafer that can be patterned into a silicon waveguide. A cladding can be deposited on the wafer and that waveguide using a plasma enhanced chemical vapor deposition (PECVD) process. When a PECVD process is used, the cladding portions that are in contact with that waveguide and in the immediate vicinity can have a lower density, and a lower refractive index n of less than (n<1.3). The lower uniform cladding refractive index can be uniform from the waveguide surfaces out to approximately one micrometer from the waveguide. This can further in result in an increased difference between the refractive index of the silicon waveguide and the adjacent lower refractive index cladding portions, which can further result in greater light confinement within the waveguide (i.e. reduced losses during transmission).
