Tall-barrier terahertz quantum cascade lasers
A terahertz quantum cascade laser is presented in which selectively placed pure AlAs barriers are used to reduce parasitic leakage currents to the conduction band continuum. The design is demonstrated to have improved temperature performance over a regrowth of the current T [subscript max] ∼ 200 K r...
