Dual Photonic–Phononic Crystal Slot Nanobeam with Gradient Cavity for Liquid Sensing

A dual photonic–phononic crystal slot nanobeam with a gradient cavity for liquid sensing is proposed and analyzed using the finite-element method. Based on the photonic and phononic crystals with mode bandgaps, both optical and acoustic waves can be confined within the slot and holes to enhance inte...
