Broadband THz absorption spectrometer based on excitonic nonlinear optical effects
A broadly tunable THz source is realized via difference frequency generation, in which an enhancement to χ((3)) that is obtained via resonant excitation of III–V semiconductor quantum well excitons is utilized. The symmetry of the quantum wells (QWs) is broken by utilizing the built-in electric-fiel...
