Paper Abstract

The effects of fabrication tolerances on the resonant frequency of Bragg gratings etched in glass waveguides are reported. The glass materials are chosen for low thermal drift of refractive index and consequent low thermal drift of Bragg resonant frequency. Fabrication and measurement of Bragg gratings with grating period held constant to 100 ppm are demonstrated. A monolithic array of notch filters with resonant frequencies shifted over a 5 nm range by choice of waveguide width, thickness, etc., is demonstrated.
