Third harmonic generation in a Quantum Cascade laser with monolithically integrated resonant optical nonlinearity
28 June 2004
We present third harmonic generation from an InGaAs/AlInAs Quantum Cascade laser based on a three-well diagonal transition active region with an integrated third-order nonlinear oscillator. The device displays pump radiation at lambda similar to 11.1 mum and third order nonlinear light generation at lambda similar to 3.7 mum as well as second harmonic generation at lambda similar to 5.4 mum.
