Low Loss 8 × 8 Silicon Photonic Banyan Switch

摘要

We design and experimentally demonstrate scalable 2×2, 4×4 and 8×8 silicon photonic thermal switches exhibiting low loss, low crosstalk, energy-efficient and error-free data transmission. Insertion loss below 3.1 dB with crosstalk of at most 20.5 dB is measured for the 8×8 SiPh thermo-optic switch.
