1. A device comprising:
one or more inputs; one or more outputs;
one or more optical waveguides configured to: receive an optical signal from at least one of the one or more inputs; and convey the optical signal to at least one of the one or more outputs;
an optical resonator configured to modulate or filter the optical signal; and
a heater configured to heat the optical resonator, the heater being line-shaped and having a first side and a second side opposite the first side, and
the optical resonator comprising a first portion at the first side of the heater and a second portion at the second side of the heater,
wherein the first portion and the second portion are adjacent the heater, and the optical resonator further comprises opposite ends that join the first portion and the second portion, the opposite ends being rounded, the opposite ends being wider than a distance between the first portion and the second portion.
