title: Suspended AlGaAs waveguides for tunable difference frequency generation in mid-infrared.
abstract: A birefringent phase-matching scheme for difference-frequency generation in a slotted air-clad waveguide with a tunable gap is proposed and theoretically analyzed. A tunability of 300 cm(-1) and an efficiency of 400 W(-1) cm(-2) is predicted.
