Popis:	Losses as low 0.65 dB cm-1 (3 ?m width) and 0.3 dB cm-1 (8 ?m width) have been measured (? = 1.15 ?m) in high-confinement (NA ? 0.45) GaAs/GaAlAs optical waveguides grown by MOCVD. The Fabry?Perot loss measurement technique used in deduced to be accurate to ±0.1 dB cm-1. These are the lowest losses reported for gudies of high electro-optic merit in III-V materials.
