Abstract

Loss measurements on ridge waveguides in LPE-grown GaInAsP at a wavelength of 1.3 μ are presented. An attenuation of 4.5dB/cm has been obtained for straight waveguides, and for curved waveguides an excess loss as low as 0.7 dB was found for a 20.8° S-bend with a radius of 300μm(⋍1.5dB/90°).
