Fast Three-Waveguide Beam Splitter/Coupler based on Invariant Engineering

Abstract

We propose fast beam coupling in a three waveguide directional coupler based on Lewis-Riesebfeld invariant theory The design of beam power converter/splitter using the dynamical invariant is discussed We use the closed form expressions for the modal power at the ouput for converter/splitter to design various approaches and simulate by beam propagation method in a three waveguide system We successfully transfer/split power form one waveguide to another or the others in different designed paths Besides we use a specific waveguide system to create a quantum Hardamard gate
