Single-Sideband Thin Film Lithium Niobate (TFLN™) Electro-optic Modulators for RF over Fiber

Abstract

A high speed thin film lithium niobate modulator device is integrated with a Bragg grating for in situ sideband filtering. The configuration has potential for high efficiency linear intensity modulation at bandwidths exceeding 70 GHz. This proof of concept study explores the benefits of in situ versus ex situ processing and examines the differences in nonlinear optical models for this case where the traditional Jacobi-Anger expansion model for phase modulation is no longer true.
