Photonic Crystal Fiber Based 1 × N Intensity and Wavelength Splitters/Couplers

Abstract This article presents three new designs of photonic crystal fiber based intensity and wavelengths splitters/couplers. Numerical simulations have demonstrated the feasibility of planar and two-dimensional 1 × 8 intensity splitters/couplers using an optical signal having, respectively, a bandwidth of 1 THz and 125 GHz around a central wavelength of 1.55 μm. A wavelength demultiplexer has also been simulated for four wavelengths (each also having a bandwidth of 125 GHz) that belong to four telecom windows used in optical fiber communications.
