Femtosecond Laser Direct Writing of Tilted Waveguide Bragg Grating for Refractive Index Sensing
We present an innovative on-chip tilted grating structure characterized by a few cladding mode resonances and strong Bragg resonance. The cladding mode resonance demonstrates favorable refractive index response, while Bragg resonance effectively solves temperature crosstalk.
