Abstract:
1. A method of using an optical waveguide within a range of temperatures, comprising: inputting an optical signal of a first frequency to an optical transmission channel; modulating said optical signal when a temperature of the optical waveguide is equal to a first temperature, said modulating performed using a first modulator circuit that includes a first resonant structure with a corresponding first resonant temperature, said first resonant temperature being equal to said first temperature; modulating said optical signal when a temperature of the optical waveguide is equal to a second temperature, said modulating performed using a second modulator circuit that includes a second resonant structure with a corresponding second resonant temperature, said second resonant temperature being equal to said second temperature, wherein said second temperature is different from said first temperature; and modulating said optical signal when a temperature of the optical waveguide is equal to a third temperature, said third temperature being in between said first and second temperatures, said modulating performed using said first and second modulator circuits during partial resonance of the first and second resonant structures at the third temperature.
