Abstract
An optical filter () comprises a multimode waveguide () and first () and second () coupling waveguides which communicate with lateral sides of the multimode waveguide. The filter operates by reproducing an optical field distribution input to the multimode waveguide via one of the coupling waveguides at the position in the multimode waveguide where the other coupling waveguide communicates with the multimode waveguide. This occurs for radiation of a wavelength to be filtered but not for radiation of other wavelengths.
