The present invention discloses an improved wavelength slicing technique for demultiplexing a composite optical signal. The technique applies a method for demultiplexing the composite optical signal for transmitting data signals over a plurality of data channels of different wavelengths represented by lambda 1, lambda 2, lambda 3, lambda 4, ... lambda n where n is a positive integer. The method includes a step a) of receiving the composite optical signal into an asymmetric wavelength slicing device through a device input port. And step b) of slicing the composite signal and extracting a first composite optical signal comprising data signals transmitted in a first set of data channels lambda 1, lambda a, lambda b, lambda c, ... lambda n-1 through a first output port. And, extracting a second composite optical signal comprising data signals transmitted in a second set of data channels lambda 2, lambda a, lambda e, lambda f, ... lambda n through a second output port wherein the second set of data channels is complimentary and asymmetric to the first set of data channels. |
