Paper Abstract

We report on a monolithic photonic chip including a microdisk for chi(2) optical interactions which is evanescently coupled with two suspended waveguides used for pump injection and nonlinear signal collection: one for critical coupling at λω ≈ 1600 nm and the other for critical coupling at λ2ω ≈ 800 nm. Our sources are CW tunable lasers: an external-cavity laser diode at ω and a Ti:Sapphire laser at 2ω, both connected to a microlensed fiber. Thanks to critical coupling at input/output wavelengths, we achieved 11% W−1 SHG efficiency. The same chip enabled us to demonstrate spontaneous parametric down-conversion (SPDC).
