Abstract

Studies have been made of the effect of boron and fluorine impurity induced disordering on the refractive index of AlxGaixAs multiple quantum well waveguides. A grating coupler formed in low-index material was used to determine experimentally the changes in refractive index obtained in partially disordered material. Over the measured wavelength range 820-920 nm substantial changes 1 in the refractive index were observed. Fluorine was found to produce larger changes than boron for similar annealing conditions.
