Spherical multipath double-heterojunction quantum dot-based artificial compound eye laser system

Abstract

The invention discloses a spherical multipath double-heterojunction quantum dot-based artificial compound eye laser system, which consists of a master controller, a constant current driving source and multiple quantum dot small eye laser units with the same structure, wherein each quantum dot small eye laser unit consists of a small eye laser emitting window, an external electrode, an upper-layer P-DBR (P-distributed bragg reflector), an upper blocking layer, an active area, a quantum dot, a lower blocking layer, a lower-layer N-DRB, an N<+> type substrate and an internal electrode. N quantum dot small eye laser units have the same geometric structure and matter distribution, emitted laser has the same wavelength characteristic, and N beams of continuous laser emitted from the small eye laser emitting windows along the directions of optical axes of each small eye and having a wavelength lambada are finally obtained. The system has the beneficial effects that key problems about efficient miniaturization of a multi-channel parallel compound eye laser are solved. According to an artificial compound eye laser, the wavelength and the intensity are selected, so that a compound eye can be adapted to different environments to detect various characteristics of stimulated emission, scattering and the like of a target.

Description

technical field [0001] The invention relates to a laser system, in particular to an artificial compound eye laser system based on spherical multi-channel double heterojunction quantum dots. Background technique [0002] Artificial compound eye (ACE) is an optical system that simulates the compound eye structure of insects in nature. It replaces the widely used single-aperture optical system with a multi-aperture optical system to achieve miniaturization, light weight, and increased field of view of the entire system. big purpose. In recent years, foreign researchers have successfully produced various artificial compound eye systems with different structures and uses. For example, Luke P.Lee of the University of California, Berkeley, USA, realized a hemispherical ACE by using polymer microlenses, polymer cones, and self-aligning waveguides; The cross-sectional shape of each ommatidium microprism is calculated, and the imaging of the wide-field scene on the plane detector is...

Problems solved by technology

Most of the current artificial compound eyes are passive compound eyes, that is, they passively receive electromagnetic wave information of various bands outside, and then analyze and process them. They are easily restricted by environmental factors, affecting the signal-to-noise ratio and sensitivity of detection, and further deteriorating the detection effect.
