Optimization of the LEAC Optoelectronic Sensor: Modeling, Design, Fabrication, and Validation for Real-Time Sensing with Multi-Analyte Capability
Abstract: Design, modeling, fabrication, and experimental
validation of Local Evanescent Array Coupled
(LEAC) sensor is presented. The LEAC sensor is a
waveguide-based, CMOS-compatible lab-on-a-chip
sensor, which has recently been demonstrated for
real-time refractive index measurements.
Furthermore, multi-analyte capability has been
demonstrated on a single waveguide. Device
performance is discussed alongside plans for
future research work, which leverages the chip's
high sensitivity and small footprint for both
environmental and biological sensing applications.
