Abstract

We demonstrate low‐loss optical mode‐size tapers in InGaAsP/InP optical waveguides fabricated by selective organometallic chemical vapor deposition. The tapers increase the vertical mode size by ≊300%. Taper losses as low as 0.4 dB (on‐chip, excluding coupling) were achieved, with 2.6 dB coupling loss to a flat‐end, single‐mode fiber at 1540 nm wavelength.
