Abstract
PURPOSE: To provide a miniature as well as highly efficient device by providing a stripe for each wave-length above a single semiconductor tip so that radiations of various wave-lengths are collected, dispersed and emitted by means of a prism.
CONSTITUTION: Stripes STP1 to STPm, their number being m, present above a semiconductor tip TP are so arranged that their extensions meet together at a point M on an edge of the semiconductor tip. The space from the polyhedral faces of tip TP to the radiating face RD of a prism PRM forms a resonator for wave- lengths λ1 to λm which are determined by each stripe, thus radiation of individual wave-lengths being obtained. Multiwave-length light is emitted simultaneously and vertically from face RD of prism PRM and can be transmitted farther by means of an optical fiber OPF.
