Gain in terahertz quantum cascade lasers
This thesis focuses on experiments involving coupled cavity THz QCLs. These take the form of either monolithic devices with etched gaps to form two cavities on the same device, or separate devices aligned under vacuum and at cryogenic temperatures using a specially built piezo-electric microposition...
