Refractive Index Sensing in a Monolithic Micro-Optofluidic Lithium Niobate Chip
We report a micro-optofluidic refractive index sensor integrating a femtosecond laser-written waveguide and selectively etched channel in lithium niobate. Fabry-Pérot spectra show a 1212 nm/RIU sensitivity at 1554 nm for refractive index steps of 10⁻ 3 .
