Milliwatt average power terahertz quantum cascade lasers (THz-QCLs) combined with microbolometer focal plane array cameras allow for acquisition rates on the order of 1×10 6 pixels/s. This system enables real-time imaging in transmission and reflect

© 2016 SPIE. Milliwatt average power terahertz quantum cascade lasers (THz-QCLs, 2 THz to 5 THz) have been developed for spectroscopy and as local oscillators for heterodyne receivers. Novel DFB THz-QCLs have been fabricated and show single-mode ope

In the following, we report on the design and implementation of an inexpensive thermal source for THz radiation with a highly tunable radiation signature. It consists of five 350-μm-thick Si wafers, each spaced 1 mm apart. The thermal emission of th

We explore the degree to which infrared thermal emission can be tailored using an array of dielectric spheres coated with a negative permittivity material. The spheres themselves have absorption peaks in the IR. The emission spectrum is then modified

We are exploring the degree to which one can control the spectral emission of heated photonic crystals (or, more generally, electromagnetic crystal) structures in the THz frequency range. Because THz frequencies are well below the room temperature th

Terahertz (THz) frequency radiation has many spectroscopic and imaging applications. Because it suffers from a limited propagation distance in air due to strong water absorption and a historic lack of inexpensive sources, radiation in the THz frequen
