Bidirectional Nonlinear Optical Tomography: Unbiased Characterization of Off- and On-Chip Coupling Efficiencies

Published in arXiv:2510.13110, 2025

We present bidirectional nonlinear optical tomography (BNOT), a hardware-compatible metrology that breaks the degeneracy of input and output coupling efficiencies to enable unbiased benchmarking of nonlinear photonic integrated circuits.

Wafer-Scale Squeezed-Light Chips

Published in arXiv:2509.10445, 2025

We report the wafer-scale fabrication, generation, and characterization of two-mode squeezed-vacuum states on a fully CMOS-compatible silicon nitride PIC platform. This work demonstrates excellent uniformity across a 4-inch wafer and establishes a reproducible route for scalable continuous-variable quantum information processing.
