ABSTRACT:
This specification discloses a power polarization beam combiner and its applications in fiber communications. The power polarization beam combiner uses the photonic band gap formed in a photonic crystal to produce a left-hand material with a negative refractive index and high dispersion rate. Using such properties of the photonic crystal, several beams with different wavelengths and polarizations are combined and output to a common port.
