Abstract

We present in this work the proceedings of dispersion engineering in CMOS compatible photonic chips for frequency conversion in the scale of hundreds of Terahertz in microresonators. These systems present great potential for integrated light generation with non-classical properties for use in quantum information science. This is the first work to use higher-order modes to obtain the zero dispersion wavelength close to 795 nm. We show that with a delicate balance between second- and fourth-order dispersion terms, two intense beams are generated that can possibly share quantum information between atomic lines and telecommunication band.
