Processing device for reducing optical waveguide loss

The utility model provides a processing device used for reducing optical waveguide loss. The processing device comprises a heating device and a heat conduction member. The heating device at least comprises a heating plate and a temperature control system in control connection with the heating plate, and the heating plate is provided with an exposed heating surface; the heat conduction piece is placed on the heating surface and is used for bearing a photon chip. According to the processing device, the heating plate with the exposed heating surface is arranged, so that the design of an open heating device is realized, and the defect that stress distribution on a photon chip is changed due to the fact that a furnace door needs to be opened for operation of a closed heating furnace is overcome; and meanwhile, through the arrangement of the heat conduction piece, when the temperature of the heating plate is reduced to the target temperature, the heat conduction piece and the photon chip can be directly taken down
