Abstract
We demonstrate the simultaneous existence of slow photonic and phononic modes in a fishbone-like one-dimensional phoxonic crystal nanobeam. The phoxonic crystal nanobeam, which is formed by a suspended fishbone-like silicon waveguide, is not only an optical one-dimensional grating waveguide but also a waveguide with acoustic local resonance. Because of the slow group velocities, the acousto-optical interactions are significantly enhanced. The operating optical wavelength and acoustic frequency can be manipulated individually by varying certain geometric parameters of the nanobeam.
