| 英文摘要 | We propose a new type of 3 db optical power splitter by splitting reflected field in photonic bandgaps (pbgs) based on photonic crystal waveguides (pcws) with a triangular lattice of air holes. by employing pbgs effect, the propagation fields with frequencies under the cutoff frequency of guided modes in a modulated pcw (mpcw) are reflected back and output from two symmetrically placed waveguides. as a consecutive section of input pcw, the mpcw is realized by varying the size of the border holes adjacent to the pcw core. a nearly full transmission with a wide bandwidth is achieved only by introducing a defect hole in the mpcw. it provides a new method and a compact model to split input power in pcw devices and can find practical applications in future photonic integrated circuits.
