Abstract
We demonstrate a tapered ridge mode expanded laser with reduced far-fi eld divergence angles (9.5 degrees x 22 degrees) and improved coupling to cleaved single-mode fibers (SMF) (3.7-dB coupling toss). This devi ce was grown in a single epitaxial growth and was processed using conv entional fabrication techniques, thus making it very attractive for lo w-cost manufacturing. This scheme also represents a general method by which active gain regions can be introduced into passive optical devic es like beam splitters and combiners.
