NETWORK OF QUANTUM CASCADE LASERS WITH ANTIGUIDING BURIED IN A TYPE IV MATERIAL AND WITH SINGLE-LOBE EMISSION

摘要

A laser includes a network of micro-ridges of quantum cascade lasers of preset emission wavelength, the micro-ridges, which are of preset widths, forming active zones of refractive index nza that are spaced apart from each other by an inter-ridge material of refractive index ne, with nzane. The inter-ridge material is a group-IV material is also provided.
