On-chip Quantum Interference of Transverse Modes with Inverse Designed Structures

Year: 2024

Type: conference-paper

Abstract: Transverse spatial modes have become an increasingly popular degree-of-freedom for encoding quantum information owing to the compact implementation when compared to others such as path. Here we present the demonstration of two photon Hong-Ou-Mandel interference between the different transverse modes in a multimode silicon photonic chip using a compact inverse designed beam splitter with up to 99.56 0.64% interference visibility. We achieve high visibilities across both multiple copies of ±the same design and among different designs. This work demonstrates the potential of inverse designed devices for quantum information processing with transverse spatial modes.
