Micro spectrometer device based on arrayed waveguide grating

Abstract

The invention discloses a micro spectrometer device based on an arrayed waveguide grating and belongs to the technical field of the improvement and innovation of micro spectrometer devices. The devicecomprises a metal base for support and heat radiation, a metal shell used for protection and sealing, an optical interface used for optical fiber input, a single-fiber tail fiber used for end face coupling, a waveguide array grating chip is used for light splitting, a copper sheet used for heat conduction, a semiconductor refrigerator, a CCD detector, and an electrical interface used for connecting the CCD detector and the semiconductor refrigerator. Analysis polychromatic light passes through the optical interface and enters the grating array waveguide chip through a single fiber for light splitting, and the light is directly detected and analyzed by the CCD detector to form a spectrum. According to the device, the size of the spectrometer is greatly reduced, the high-precision light splitting is realized, and the device can be used for the development of wearable equipment. The integrated packaging is adopted, so that the structure is more compact. The device has the advantages of small size, high precision, low price and modular assembly and can be used for large-scale production.

Description

technical field [0001] The invention relates to a micro spectrometer device based on an arrayed waveguide grating, which belongs to the improvement and innovation of the micro spectrometer device. Background technique [0002] With the development of spectroscopy, spectrometers are widely used in all aspects of our lives, whether it is food safety testing, ore coal analysis, environmental monitoring, or disease diagnosis, life science analysis, etc., are inseparable from spectrometers. Most of the traditional commercial spectrometers are large-scale volume optical spectrometers, which are generally characterized by high price, complex structure, and bulky volume. Although the traditional miniature spectrometer has reduced volume to a certain extent and is easy to carry, the complex optical path design brings various stray light effects, and the precision is not high. [0003] A micro-spectrometer device based on an arrayed waveguide grating of the present invention uses an ...
