Paper Abstract

Wavelength-division-multiplexing technology is now recognized as one of the key technologies in optical communication systems. Because it can greatly enhance the capacity of the communication systems. And the optical wavelength-division-multiplexing devices are the key parts in the wavelength-division-multiplexing technology. The authors have integrated a pair of lens and a grating on a piece of K7 glass substrate in order to achieve the optical wavelength-division-multiplexing function. The optical wavelength-division-multiplexing's wavelength ranges from 1.10 micrometers to 1.55 micrometers and its central wavelength is 1.3 micrometers . The channel's interval is 40 nm and the available channels number >= 12. The insertion losses <EQ 8 dB and the channel's crosstalk is better than -20 dB. The waveguide is K+ ion exchange waveguide.
