Sector-shaped closely-packed laser

Abstract

The present disclosure discloses a sector-shaped closely-packed laser generator, comprising a module packaging unit and a closely-packed output unit; the module packaging unit is provided therein with a plurality of single-die modules, and each of the single-die modules has a coupling optical fiber; the closely-packed output unit is provided therein with a silicon wafer whose surface has a plurality of V-shaped grooves, and the plurality of V-shaped grooves are arranged into a sector shape; and the coupling optical fibers of the single-die modules protrude from the module packaging unit and enter the closely-packed output unit, and are arranged in the V-shaped grooves after coating layers being stripped, to emit laser lights in directions of the arrangement of the V-shaped grooves. In the present application, the plurality of single-die modules are collectively disposed in the module packaging unit, and the coupling optical fibers of the single-die modules are led out and arranged in the V-shaped grooves arranged in a sector shape, which realizes the close arrangement of the coupling optical fibers, obtains the effect of modularized and integrated packaging of single die, and effectively reduces the volume of the laser generator. Furthermore, by closely arranging the coupling optical fibers in the V-shaped grooves arranged in a sector shape, the present disclosure can control the light emitting direction of the coupling optical fibers.
