Abstract: Embodiments include a photonic device with a compensation structure. The photonic device includes a waveguide with a refractive index which changes according to the thermo-optic effect as a temperature of the photonic device fluctuates. The compensation structure is positioned on the photonic device to counteract or otherwise alter the thermo-optic effect on the refractive index of the waveguide in order to prevent malfunctions of the photonic device.
