Abstract :
A novel selective radiation-wavelength filter based on a multilayer cladding waveguide was proposed and analyzed. Light with a passband wavelength is selectively radiated into a photodetector on substrate, partially using a vertical coupling between the core and one of cladding layers. Narrow and sideband-free filtering characteristic and compact size are achievable with low insertion loss.<>
