An elegant length tolerant design of waveguide arrays for the generation of N-partite two photon W state
Surajit Paul, Krishnan Thyagarajan · 2014
An elegant design of a waveguide array consisting of (2N-1) identical single mode optical waveguides is introduced to create ‘N’ partite two photon W state that illustrates much enhanced tolerance to the fabrication conditions and experimental perturbations.
