We report on a multispectral superconducting nanowire single-photon detector based on a thickness-modulated optical film stack. This unique optical film structure provides a modulated reflection bands used for single-photon detection in well-separated multiple wavelength ranges. The fabricated detector shows four detection bands with the system detection efficiencies of 76.2%, 76.9%, 81.3%, and 85.0% at the wavelengths of 505, 610, 1030, and 1550 nm, respectively. A 4-pixel multispectral detector array is then demonstrated, and a photon flux reconstruction experiment is performed to reconstruct the photon flux at the wavelengths of interest. The present multispectral detector enriches the available optical architectures and may have interesting multispectral applications such as multispectral ranging or imaging.
