| description | The invention discloses a customized spectrometer based on a Bragg grating, which comprises an end face coupling input port, a first input waveguide, a first-stage filtering channel A1, a second-stage filtering channel A2,..., an Nth-stage filtering channel AN, a heating electrode, a first bonding pad, a second bonding pad, an output waveguide and an output port. The first-stage filtering channel A1, the second-stage filtering channel A2,..., and the Nth-stage filtering channel AN are sequentially cascaded, the output end of the previous-stage filtering channel is connected with the input end of the next-stage filtering channel through the connection input waveguide, and the end face coupling input port is connected to the input end of the first-stage filtering channel A1 through the first input waveguide, and the output end of the Nth-stage filtering channel AN is connected with the output port through the output waveguide.
