Abstract :
We demonstrate difference frequency generation of 8.66 μm to 11.34 μm light in intersubband InGaAs-AlAs quantum wells by mixing of 1.92 μm±25 nm and 2.39 μm±39 nm with a peak χ (2) of 12±1 nm/V, 65 times that of GaAs. The intersubband absorption and second harmonic generation χ(2) are also measured and compared with theory
