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.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-08-17t00:44:42z no. of bitstreams: 1 ultracompact triplexer by coupling and decoupling of multiple photonic crystal waveguides.pdf: 654554 bytes, checksum: 037de713d08b6a5b02e48686e2a1bf31 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-08-17t00:58:27z (gmt) no. of bitstreams: 1 ultracompact triplexer by coupling and decoupling of multiple photonic crystal waveguides.pdf: 654554 bytes, checksum: 037de713d08b6a5b02e48686e2a1bf31 (md5); made available in dspace on 2010-08-17t00:58:27z (gmt). no. of bitstreams: 1 ultracompact triplexer by coupling and decoupling of multiple photonic crystal waveguides.pdf: 654554 bytes, checksum: 037de713d08b6a5b02e48686e2a1bf31 (md5) previous issue date: 2010; this work was supported by the natural science foundation of china (contract no. 10664002), the natural science foundation of jiangxi province (contract nos 0612043, 2007gqw2057, 2007gzw2457), and by the open project of the state key laboratory on integrated optoelectronics of the institute of semiconductors (contract no ioskl-kf200901). we are grateful to the referee for significant suggestions.; 国内
