Abstract

For its low cost and high quality properties, wavelength division multiplexer based on arrayed waveguide grating is used widely in optical communication components and systems. For the purpose to reduce the cost and improve the quality of communication systems, wavelength division multiplexer with wide and low crosstalk is necessary. In this paper, a new wavelength division multiplexer with wide pass-band and lower crosstalk is designed, where special tapered couplers with split structures are used as input waveguides, and experiment results shows that the transmission with wide pass-band and lower crosstalk could be obtained.
