Slant-Face Fiber Side Coupling of Vertical Cavity Surface Emitting Laser

Article Preview

Abstract:

Slant-face fiber side coupling of vertical cavity surface emitting laser (VCSEL) is reported. The direct coupling efficiency can reach 70%. The relative coupling efficiency variety caused by the position displacement and angle displacement was studied respectively. It is found that the cylinder of the fiber can collimate the divergent laser beam and improve aligning tolerance.
