Abstract
A method of creating an optical filter for selectively filtering an optical signal transmitted through the filter, the method comprising: constructing a Bragg grating in an optical element coupled to an optical path way for the transmission of the optical signal to suppress background radiation; and adjusting the coupling so as to produce a selective transmission spectrum in according with predetermined requirements.
