Abstract

We discuss a design of short-wavelength quantum cascade laser sources based on intracavity second harmonic generation. A passive heterostructure tailored for giant optical nonlinearity is integrated on top of an active region and patterned for quasiphase matching. We demonstrate operation of λ≈3.6 μm lattice-matched InGaAs/AlInAs/InP sources with approximately 6 μW of second-harmonic output at room temperature and conversion efficiency of approximately 130 μW/W². Threshold current densities of devices with a nonlinear section were similar to that of the reference lasers without the nonlinear section.
