An electrooptical device comprises a semiconductor laser to which a plurality of optical transmission fibers are coupled. An input transmission fiber and at least one output transmission fiber are combined to form a tapered common fiber end portion. The common end portion has a transverse dimension on the order of that of a single transmission fiber. By coupling this end portion to one radiation-emitting surface of the semiconductor laser, a standard laser package may be employed and several new uses become feasible in practice.
