Spectrum scanning assembly and optical semiconductor element

Abstract

The invention relates to a spectrum scanning assembly and an optical semiconductor element. The spectrum scanning assembly includes a band-pass waveguide assembly and multiple micro-ring resonators, and the band-pass waveguide assembly is respectively connected to the multiple micro-ring resonators; in which: the band-pass waveguide assembly is used to divide an optical signal to be tested into multiple band-pass optical signals with different central wavelengths and then respectively input into the multiple micro-ring resonators; each micro-ring resonator is used to perform scanning for resonant wavelengths in the band-pass optical signals to form first spectral information; in which after beam combination is performed on multiple pieces of first spectral information formed by the multiple micro-ring resonators, second spectral information may be formed. The spectrum scanning assembly and the optical semiconductor element of the invention have high spectral scanning precision.
