Layer-Engineered Frustrated Total Internal Reflection (FTIR) Sensors for Structural Integrity and Tamper Detection
This technology is a thin, multilayered optical sensor designed to detect physical damage, tampering, or material loss before failure occurs in microelectronics, aerospace, and advanced packaging platforms. It uses light, rather than electrical signals, to passively monitor whether a structure has been disturbed. When a layer is thinned, cracked, deformed,...

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...
