1. A method for operating an optical device, wherein the optical device includes a first waveguide, multiple ring-shaped waveguides adjacent to the first waveguide, and multiple heaters coupled to the ring-shaped waveguides in one-to-one correspondence, wherein each of the multiple heaters is supplied with an initial electric current, the method comprising:
coupling a first light source with a first wavelength to the first waveguide;
increasing electric current through the heaters until a first one of the ring-shaped waveguides resonates, wherein the first one of the ring-shaped waveguides is coupled to a first one of the heaters;
assigning the first one of the ring-shaped waveguides to the first wavelength;
resetting the electric current through the heaters or the heaters excluding the first one of the heaters to the initial electric current;
coupling a second light source with a second wavelength to the first waveguide, wherein the second wavelength is different from the first wavelength;
increasing the electric current through the heaters or the heaters excluding the first one of the heaters until a second one of the ring-shaped waveguides resonates, wherein the second one of the ring-shaped waveguides is different from the first one of the ring-shaped waveguides; and
assigning the second one of the ring-shaped waveguides to the second wavelength.
