High-Performance Balanced Photodiode on Thin-Film Lithium Niobate Platform
We demonstrate a high-performance balanced photodiode heterogeneously integrated thin-film lithium niobate. The device exhibits a high 3-dB bandwidth of 55 GHz and a common-mode rejection ratio greater than 10 dB in the DC-67 GHz frequency range. A pair of balanced photodiodes and a commercial 90° optical hybrid coupler form a wideband coherent receiver to achieve high-quality reception of 100 Gbaud quadrature phase-shift keying (200 Gbit/s) and 16 quadrature amplitude modulation (400 Gbit/s) signals.
