“…As such, several waveguide structures have been developed so far by many groups in order to achieve it in AlGaAs waveguides. These include multilayer AlGaAs/Al 2 O 3 waveguides for artificial form birefringence phase matching (FBPM) [69,70], engineered-waveguides for modal phase matching (MPM) [71,72], Bragg reflection waveguides (BRW) for MPM [73], orientation patterned GaAs (OP-GaAs) for quasi-phase matching (QPM) via domain reversal [74], and periodically switching nonlinearity (PSN) via etch-and-regrowth for QPM [75]. A comprehensive discussion of these techniques may be found in Ref.…”

We review our recent progresses on frequency conversion in integrated devices, focusing primarily on experiments based on strip-loaded and quantum-well intermixed AlGaAs waveguides, and on CMOS-compatible high-index doped silica glass waveguides. The former includes both second-and third-order interactions, demonstrating wavelength 2 conversion by tunable difference-frequency generation over a bandwidth of more than 100 nm, as well as broadband self-phase modulation and tunable four-wave mixing. The latter includes four-wave mixing using low-power continuous-wave light in microring resonators as well as hyper-parametric oscillation in a high quality factor resonator, towards the realization of an integrated multiple wavelength source with important applications for telecommunications, spectroscopy, and metrology.

“…Although quasi-phase matching was recently demonstrated in GaAs waveguides, 2 the high scattering losses limit the useful interaction length to about 1 mm. We recently proposed 3,4 to use the huge form birefringence in multilayer AlGaAs/͑Al oxide͒ waveguides to achieve phase matching. 5 These highindex contrast multilayers are obtained by selective lateral oxidation of AlGaAs/AlAs heterostructures.…”

We demonstrate difference frequency generation of 4 μm radiation from 1 to 1.32 μm pumps in GaAs-based waveguides. Phase matching is obtained by using form birefringence in selectively oxidized AlGaAs/AlAs multilayers. A tunability over 50 cm−1 around 4 μm is demonstrated by changing the waveguide temperature and one pump wavelength. A much larger tunability may be achieved by using two tunable sources.

“…Because the index difference between these two materials is so large, new optical devices can be fabricated which are not possible using conventional III-V epitaxy. For example, semiconductor waveguides containing Al 2 O 3 layers can have an extremely large polarization birefringence [11]. This birefringence has recently been exploited to phase match frequency mixing processes in co-propagating geometries [12].…”
