Abstract

A deterministic design and manufacturing of an ultrahigh Q-factor, wavelength-scale optical cavity is invented and experimentally demonstrated. The design can be implemented on photonic crystal nanobeam cavities, which are based on 1D optical waveguides. The waveguide has dielectric index alternations that provide constructive interference and produces optical resonance.
