Ultra-Fast Self-Adaptive Phase-Error Calibration for Dual MZI-based Silicon Photonic Switch Fabric

Inhalt:
Fully automatic phase-error calibration across a 256 dual Mach-Zehnder-interferometers-based 8×8 non-blocking silicon photonic switch fabric with polarization diversity was demonstrated. We achieve an ultra-fast and highly accurate calibration by only sampling 3.6 measurement points for one switch state, close to the theoretical limit of 3.
