Fig. 2 (a) shows the dispersion relationship with zero group velocities at the edge of the Brillouin zone for the designed slow light phase shifter, which is calculated using the 3D PWE method.

Slow light engineering in a photonic crystal slab waveguide …

WebbThis slow light waveguide includes an initial region which extends, along an optical axis, from a start starting from which the width of a central waveguide begins to continuously … WebbThe doubly periodic Si photonic crystal waveguide operates as a nonmechanical beam-steering device that can be applied in light detection and ranging. In this Letter, we develop and describe a prism lens that collimates a fan-shaped beam, emitted from the waveguide independent of the steering angle. inyeccion flecha
