Coupling is very selective to the mode. Different modes corresponding to different frequencies/wavelength can be coupled and filtered. May SPR phenomenon be useful to get very narrow band filters....

What is your ideal configuration? A wave guide filter? An aperture filter? Something else? Are you filtering surface waves, guided modes, a beam?
