ABSTRACT: In this paper, an optical waveguide junction is
introduced to reduce crosstalk based on a hexagonal structure of photonic
crystals for TE modes. The wavelength is 1330 nm which is an
important wavelength for optical fiber data transmission. Simulation results
show that the proposed design exhibits a reduction of -50 dB in
crosstalk. It translates to a considerable isolation improvement between two
crossover waveguides. FDTD method is used to obtain the transmission coefficient.
