Paper Abstract

We discuss the generation of THz radiation at room temperature by the exploitation of a nonlinear optical process taking place in a high quality factor AlGaAs microcavity. The approach is grounded on 1) a novel quasi-phase-matching scheme for parametric processes involving whispering-gallery modes circulating in nonlinear microcylinders; and 2) recent advances concerning quantum dots microcylindrical lasers. After a brief summary of the theory used to describe the nonlinear process, we present the results of our modeling in the case of a passive device pumped by two lasers at wavelengths close to 1.3 μm. Finally, we conclude with preliminary measurements performed with a tapered fiber.
