Athermal On-Chip Cavities and Filters Using Sagnac Loop Reflectors
This invention replaces traditional Fabry-Perot mirrors with Sagnac loop reflectors where the reflections from the loop have a phase response that depends on both the waveguide index and loop radius. These are both temperature-dependent properties, meaning that by choosing the right loop size and waveguide geometry, the phase drift from the mirrors...
