Title: Dielectric waveguide with transverse index variation that support a zero group velocity mode at a non-zero longitudinal wavevector

Abstract

Optical components including a laser based on a dielectric waveguide extending along a waveguide axis and having a refractive index cross-section perpendicular to the waveguide axis, the refractive index cross-section supporting an electromagnetic mode having a zero group velocity for a non-zero wavevector along the waveguide axis.
