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 effec…
