Wavelength Division MUX/DEMUX Using On-Chip Sagnac Loop Based Fabry Perot Cavities
This invention relates to integrated photonic devices for wavelength division multiplexing (WDM). The architecture implements an array of Fabry-Perot cavities formed using Sagnac loop reflectors as mirrors. Each cavity is side-coupled to a waveguide that carries a broadband optical signal, which ultimately enables multi-channel WDM operation.

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...
