Paper Abstract

A vectorial coupled mode theory is used to analyze sol-gel ridge waveguides with UV-light-imprinted Bragg gratings. The effect of device parameters on the grating reflectivity is investigated. It is shown that 100% reflectivity for both TE and TM modes can be achieved using short (1 to 2 mm) gratings. The measured reflectivity in a ridge waveguide with a grating agrees with the theoretical predictions for TE and TM modes.
