Waveguide Superlattice-based Optical Phased Array: Balancing Superlattice Lobe and Crosstalk Suppression

Not Accessible

Your library or personal account may give you access

Abstract

The crucial factors governing the behavior of waveguide superlattice-based optical phased arrays are investigated. The superlattice-induced extra lobes can be minimized with sophisticated supercells while the inter-waveguide crosstalk still needs to be judiciously balanced.
