Problems solved by technology

The working substance is a substance that emits laser light, but it cannot emit laser light at any time. It must be excited by a pump source to form a particle population inversion and emit laser light. However, the laser light obtained in this way has a short life and low intensity. High, and there are many light wave modes, and the directivity is very poor

Embodiment Construction

[0019] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used in the description of the present invention in this specification are only for t...

Abstract

The invention discloses a vertical cavity surface emitting laser (VCSEL) array module and a display device. The VCSEL array module comprises an active matrix display control circuit substrate, a reflector array formed by a first distributed Bragg reflection grating, a semiconductor light-emitting quantum layer array, an aperture array for limiting current distribution, and a reflector array formedby a second distributed Bragg reflection grating; an active matrix display control circuit in the active matrix display control circuit substrate drives the semiconductor light-emitting quantum layerarray to emit light through a metal electrode array. The invention provides a high-density VCSEL array module capable of being produced in scale, the test can be performed in the production process,so that the process can be simplified, and the manufacturing cost can be lowered; the VCSEL array module can be used for multiple applications including light communication, 3D terrain induction, display and printing, and has the stable product structure.

Description

technical field [0001] The invention relates to the field of vertical cavity surface emitting lasers, in particular to a vertical cavity surface emitting laser array module and a display device. Background technique [0002] Vertical cavity surface emitting laser, also known as vertical cavity surface emitting laser (VCSEL), is a new type of optoelectronic device with great development prospects. It is an f-p laser whose light output direction is perpendicular to the surface of the resonator. The superiority of vertical cavity surface emitting lasers has attracted widespread attention, and has been developed rapidly in the fields of structure, material, wavelength and application. [0003] Vertical cavity surface emitting laser is mainly composed of three parts, including laser working substance, pump source and optical resonator. The working substance is a substance that emits laser light, but it cannot emit laser light at any time. It must be excited by a pump source to f...
