摘要：

An on-chip triplexer based on cascaded tilted multimode interference (MMI) couplers has been demonstrated to separate the 1310 nm wavelength band into one port and 1490 nm and 1550 nm wavelength bands into the other two ports respectively. By utilizing the dispersive self-imaging and pseudo self-imaging, the device length is not critically determined by the common multiple of beat lengths for different wavelengths. The total device size can be reduced to similar to 450 mu m, which is half of the butterfly structure reported. The whole device, fabricated with only one fully-etching step, is characterized with <-15 dB low crosstalk (CT) and similar to 1 dB insertion loss (IL). (C) 2017 Elsevier B.V. All rights reserved.
