Abstract

The invention provides a vertical cavity surface emitting laser array and a manufacturing method and application thereof. The vertical cavity surface emitting laser array comprises at least two emitters, wherein each emitter comprises at least two emitting units, and a first conductive connection layer is arranged between the emitting units; and at least two insulating regions which are arranged between at least two emitters, wherein at least two emitters are connected in series. The vertical cavity surface emitting laser array can improve the light emitting area.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a vertical cavity surface emitting laser array and a manufacturing method and application thereof. Background technique [0002] Vertical cavity surface emitting laser (Vertical Cavity Surface Emitting Laser, VCSEL) is developed on the basis of gallium arsenide semiconductor materials. The advantages of circular output spot, single longitudinal mode output, small threshold current, low price, and easy integration into large-area arrays are widely used in optical communication, optical interconnection, optical storage and other fields. [0003] The Vertical Cavity Surface Emitting Laser (VCSEL) is a new type of laser that emits light from the vertical surface. Its structure is different from the traditional edge emitting laser. It has many advantages: the length of the optical cavity is extremely short, which leads to the wide The single longitudinal mode operation can be realized...
