Abstract :
Summary form only given. The authors have developed an all-epitaxial technique to fabricate orientation-patterned GaAs films. This technique could make possible orientation-patterned waveguide devices with extremely small (<100 /spl Aring/) corrugations and thereby reduce associated waveguide losses in these devices, as scattering losses scale nonlinearily with corrugation amplitude.
