A first one of the stubs has a length n.lambda..sub.1/4 selected so that the stub acts as a notch filter at a first rejection wavelength .lambda..sub.1, a second one of the stubs has a length m.lambda..sub.2/4 selected so that the stub acts as a notch filter at a second rejection wavelength .lambda..sub.2, and n and m are different integers.
