Abstract
A wavelength router is developed for routing signals from any input to any output in a wavelength division multiplexing (WDM) network. It uses an integrated grating wavelength demultiplexer which couples all wavelengths to a single input waveguide. The finite spectral range of the device is designed such that the adjacent diffraction orders couple the remaining wavelengths to the output. By designing the grating in such a way that the distance between the diffraction orders is a multiple of the output waveguide spacing, any required path can be achieved by choice of wavelength without the need for wavelength conversion.
