Problems solved by technology

[0003] It is difficult for traditional superluminescent light-emitting diodes to meet the requirements of high power and wide spectrum at the same time
Because the traditional superluminescent light-emitting diodes use semiconductor materials with uniform energy bands as the gain region, the radiated light has an inherent correlation. With the increase of the output power, the radiated light is quickly lased to a few modes, and the output spectrum changes rapidly. narrow

Abstract

The invention discloses a wide-spectrum high-power semiconductor superradiance LED, which comprises a substrate and a gain medium positioned on the substrate, wherein the gain medium is formed by use of semiconductor material with an energy band structure and spatial variation. The invention also discloses a method for manufacturing wide-spectrum high-power semiconductor superradiance LED. As theinvention adopts the semiconductor material with an energy band structure and spatial variation as the gain medium, the radiation light of the superradiance LED has internal incoherence, so that wide-spectrum output can still be maintained under high output power.

Description

technical field [0001] The invention relates to the technical field of semiconductor superluminescent light-emitting diodes, in particular to a method for manufacturing a wide-spectrum and high-power semiconductor superluminescent light-emitting diode. Background technique [0002] Semiconductor superluminescent light-emitting diodes have a wide range of applications in fiber optic gyroscopes, optical test equipment, fiber optic sensing systems, fiber optic communication systems, and optical tomography. In the above applications, in order to reduce Reyleigh backscattering and improve system accuracy, it is necessary for superluminescent light-emitting diodes to have a wide spectrum. Due to the coupling loss, transmission loss, and splitting / combining loss in the actual system, some applications (such as distributed optical fiber sensing systems) also require superluminescent light-emitting diodes to have a large power output at the same time to improve the sensitivity of the...
