Diffraction engineering for silicon waveguide grating antenna by harnessing bound state in the continuum
Silicon waveguide grating antennas (SWGAs) have been widely employed to interface the guided and radiation modes in various integrated photonic systems. However, ultrasmall feature sizes or heteromaterial integrations are usually required to obtain long propagation length and small far-field diverge...
