Electric field sensor based on thin film lithium niobate

Abstract

Thin film lithium niobate based electric field sensing is demonstrated using both micro-ring and Mach-Zehnder modulators. A high sensitivity of 80 mV/(m.Hz1/2) and of 2.2 V/(m.Hz1/2) is achieved using micro-ring modulators and Mach-Zehnder modulators, respectively.
