InGaP-on-insulator Waveguides for Entangled Pair Generation
We demonstrate efficient 1550 nm second-harmonic generation in InGaP-on-insulator waveg-uides and report the first wafer-scale nonlinear measurements. Fabricated devices exhibit loss <2 dB/cm, high thickness uniformity, and a <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$d_{14}$</tex> coefficient of 121 pm/V. Observed phase-matching trends expose dispersion-model limitations, informing future CMOS-compatible quantum photonic designs. ©2025 The Author(s)
