THz QCLs for heterodyne receivers and wavelength modulation spectroscopy

Show other versions (1)

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 operation. The narrow line widths of < 10 MHz and stark shift t...
