Towards entangled photon pair generation from SiC-based microring resonator

Entangled photon sources are fundamental building blocks for quantum communication and quantum networks. Recently, silicon carbide emerged as a promising material for integrated quantum devices since it is CMOS compatible with favorable mechanical, electrical and photonic properties. In this work, we report the progress on the entangled photon pair generation at the telecom wavelength (1550 nm), which is achieved by implementing the spontaneous four-wave mixing process in a compact silicon carbide microring resonator. We will present the design principle, experimental set-up, and results of this work.
