We report the results of transmission experiments performed on hybridized plasmonic metamaterial quantum cascade lasers. This device was formed by etching an array of split ring resonators (SRRs) onto the gold coated facet of a laser. Broadband midin

We show that mid infrared transmission spectroscopy of a quantum cascade laser provides clear cut information on changes in charge location at different bias. Theoretical simulations of the evolution of the gain/absorption spectrum for the $\lambda \

We report the realisation of spectroscopic broadband transmission experiments on quantum cascade lasers (QCLs) under continuous wave operating conditions for drive currents up to laser threshold. This technique allows, for the first time, spectroscop

We report broadband quantum cascade lasers emitting over a range of 6 to 8 mum at 77 K and having Jth=4.6 kA/cm2 at 300 K. Superluminescent diodes utilizing the same design will also be described.

A broadband midinfrared laser operating up to 340K in pulsed mode is presented. It was realized by incorporating seven different quantum cascade active regions with 0.2μm increments to emit at different wavelengths. Despite the relatively large wave

In this paper we apply a microscopic nonequilibrium many body Keldysh Green's functions approach to an analysis of complex intersubband optical materials and devices. The calculated absorption/gain spectra are in very good agreement with transmission
