Résumé

In this Letter, we report a Fano resonance-based highly sensitive and compact temperature sensor fabricated on thin film lithium niobate (TFLN) Suzuki phase lattice (SPL) photonic crystal. The experimental sensitivity is estimated to be 0.77 nm/degrees C with a photonic crystal size of only 25 mu m x 24 mu m. This sensitivity is 38 times larger than the intrinsic one of lithium niobate which is 0.02 nm/degrees C. The demonstrated sharp and high extinction ratio characteristics of the Fano lineshape resonance could be an excellent candidate in developing a high sensitivity temperature sensor, electric field sensor, etc. (C) 2016 Optical Society of America
