Broadly tunable lens-coupled nonlinear quantum cascade lasers in the sub-THz to THz frequency range
文献摘要：
Room-temperature terahertz(THz)quantum cascade laser sources with intracavity difference-frequency nonlin-ear mixing are electrically pumped monolithic semiconductor laser sources operating in the 0.6-6 THz spectral range.We report widely tunable,low-frequency THz quantum cascade laser sources using a lens-coupled Cherenkov waveguide scheme.Based on a watt-class high-power,λ～13.7 μm quantum cascade laser,the mono-lithic THz source is strongly coupled with a high-resistivity silicon lens,which causes a major increase in the THz coupling efficiency and demonstrates significant performance improvements.A room-temperature 1.5 THz device produces a 0.2 mW peak output power with a high-quality beam pattern.Improved THz outcoupling efficiency using the lens-coupled scheme enabled the demonstration of a high-performance external-cavity semiconductor THz source that is tunable from 420 GHz to 2 THz.The external-cavity,lens-coupled device configuration can technically be assembled into a butterfly-style package for a thumb-sized,widely frequency tunable THz semi-conductor source.
