Non-reciprocal transmission in a direct-bonded photorefractive Fe:LiNbO3 buried waveguide

Non-reciprocal transmission in a direct-bonded photorefractive Fe:LiNbO3 buried waveguide
Non-reciprocal transmission in a direct-bonded photorefractive Fe:LiNbO3 buried waveguide
We report the fabrication of a 20µm-thick photorefractive Fe:LiNbO3 planar waveguide buried in MgO:LiNbO3 by direct bonding of precision polished surfaces. Nonreciprocal transmission measurements were performed in a 3mm-long device with a continuous wave 532nm frequency-doubled YAG laser source. A Fresnel-reflection-based counterpropagating beam arrangement was used to measure a relative change in optical density of approximately 2 within the waveguide, with a photorefractive response time of 4.9ms.

Abstract

We report the fabrication of a 20µm-thick photorefractive Fe:LiNbO3 planar waveguide buried in MgO:LiNbO3 by direct bonding of precision polished surfaces. Nonreciprocal transmission measurements were performed in a 3mm-long device with a continuous wave 532nm frequency-doubled YAG laser source. A Fresnel-reflection-based counterpropagating beam arrangement was used to measure a relative change in optical density of approximately 2 within the waveguide, with a photorefractive response time of 4.9ms.
