Embodiment Construction
[0013] The following embodiments are provided in conjunction with the accompanying drawings and technical solutions:
[0014] The substrate used in this embodiment is erbium-ytterbium co-doped phosphate glass, the doping concentration of erbium-ytterbium is 1%, silver nitrate and potassium nitrate are chemically analytically pure, and the length of the substrate is 5 cm. First, wash and clean it with water, and then carry out vacuum transition. film, sputtering, photolithography and other operations, so that 27 waveguide channels with different widths will appear. At the same time, the salt preparation work is carried out, and potassium nitrate and silver nitrate are mixed according to the mass ratio of 8:1 in a naturally dark secret room. Configure the total mass of 130 grams, stir evenly, then pre-bake the waveguide and the prepared salt in a 200-degree far-infrared oven for 24 hours to remove the moisture, then raise the temperature to 350 degrees, and stabilize for 30 Minu...
