Abstract

Annealing properties of proton-exchanged optical waveguides in z-cut LiNbO3 fabricuted using toluic acid are reported. Variations in the surface refractive index and waveguide depth with annealing time are found to follow a power-taw relationship, and a minimum propagation loss of 0.23 dB/cm is measured at 0.633-µm wavelength.

Abstract

Annealing of proton-exchanged planar optical waveguides in z-cut LiNbO3 fabricated using stearic acid has been studied systematically. The effects of annealing on waveguide propagation loss, surface index change, and waveguide depth were measured as a function of annealing time, and were found to follow a power-law relationship.
