Improved transmission for photonic crystal Y-junctions

  • L. Dekkiche
  • R. Naoum


A highly efficient Y-junction based on a planar photonic crystal (PhC) platform is presented. The PhC consists of a triangular array of holes etched into GaAs/AlGaAs heterostructure. The Y-junction has smaller holes positioned at the center of the junction, giving rise to very uniform splitting and high transmission. The performance is very encouraging, with simulation transmission of approximately 50% for each arm of the Y-splitter relative to a comparable single-defect PhC waveguide.
