In order to realize such a waveguide, we employ a compound-type PC with absolute photonic bandgap and introduce a line defect with elliptical air holes. This PC waveguide realizes single-mode operation for both TE and TM waves. As an example of device application of this waveguide, a polarization splitter is demonstrated., application/pdf}, pages = {2410--2412}, title = {Photonic Crystal Waveguide Based on 2-D Photonic Crystal With Absolute Photonic Band Gap}, volume = {18}, year = {2006} }
