Abstract: An apparatus and method for spectrum detection by defect scattering calculation and reconstruction. The apparatus includes a photodetector, a light input system, a multi-mode waveguide, a random defect scattering structure and a substrate. The defect scattering structure is a recess with random quantities of size and position on the surface of the optical waveguide. The technical solution reconstructs a target spectrum by introducing random defects onto the surface of the optical waveguide to obtain scattered light, has the advantages of fewer devices, compact spatial optical path and small size compared with the traditional commercial spectrometer, effectively reduces the system complexity and cost of the spectrometer, and improves the portability of the spectrometer. This structure can reproduce an incidence spectrum well when using the calculation and reconstruction method to reconstruct the spectrum, and has a large bandwidth and high spectral resolution.
