Abstract:

The far-IR presents an interesting challenge for the development of an optical and optoelectronic infrastructure, as the III-V semiconductors that enable such extraordinary access to other portions of the EM spectrum are not well-suited for the far-IR, due to significant optical loss. These losses arise from the coupling of EM radiation to both free-carriers and phonons. While free-carrier loss can be controlled to an extent by limiting free-carrier density doping in the design and growth of semiconductor devicesmaterials, loss due to phonons is intrinsic to semiconductors in this wavelength range, and cannot be controlled in a similar fashion.
