In this letter, the observation of electronic anti-Stokes-Raman emission in quantum-cascade lasers is reported. We present two distinct active region designs with enhanced anti-Stokes-Raman nonlinearity. The pump laser is monolithically integrated with the nonlinear region in a two-stack active core within the same waveguide. Electronic Raman emission was observed in both designs. Additionally, for the design with positive detuning, an incoherent upconversion signal resulting from optical pumping is detected.
