In some implementations, a thermally-controlled photonic structure may include a suspended region that is suspended over a substrate; a plurality of bridge elements connected to the suspended region and configured to suspend the suspended region over the substrate, where a plurality of openings are defined between the plurality of bridge elements; and at least one heater element having a modulated width disposed on the suspended region. The at least one heater element having the modulated width may include at least one section of a greater width and at least one section of a lesser width. The at least one section of the greater width may be in alignment with an opening of the plurality of openings and the at least one section of the lesser width may be in alignment with a bridge element of the plurality of bridge elements.

Thermally-controlled photonic structure

A system includes a grating coupled laser and a photonic integrated circuit (PIC). The grating coupled laser includes a first waveguide and a transmit grating coupler optically coupled to the first waveguide. The PIC includes a second waveguide and a receive grating coupler optically coupled to the second waveguide. The receive grating coupler is in optical alignment with the transmit grating coupler. The receive grating coupler includes a first grating and a second grating spaced apart from and above the first grating within the PIC.
