| 英文摘要 | We investigate numerically the self-imaging effect in a system of multiple coupled photonic crystal waveguides (m-cpcws) with asymmetric coupling. then two couplers of 2-cpcws and 3-cpcws are cascaded to form an ultracompact triplexer by employing coupling and decoupling of m-cpcws. the wavelength of 1310 nm propagates along the input direction because the m-cpcws are decoupled at the same decoupling frequency. the other two wavelengths (1490 and 1550 nm) are separated by combining multimode interference and the dual mode coupling effect. only by introducing a single defect near the crossing point between two output photonic crystal waveguides (pcws) are the high extinction ratios for the three wavelengths achieved simultaneously. |
