Difference frequency generation from integrated nonlinearities in twowavelength quantum cascade lasers Conference Paper uri icon


  • Evidence for Difference Frequency Generation in Quantum Cascade Lasers with integrated nonlinearities is presented. Light at the difference frequency (λ = 13.3μm) is detected from a twowavelength (λ = 5.3μm and 8.8μm) laser processed with a splitridge configuration. © 2006 Optical Society of America.
