ABSTRACT:
A wide-band optical signal amplifying circuit having gain exhibiting less wavelength dependency for amplifying optical signal and analogue-modulated optical signal. The optical signal amplifying circuit includes one or a plurality of optical amplifiers for amplifying en bloc optical signal components of respective wave-lengths of a wavelength-multiplexed optical signal and a multi-cavity type or the like dielectric multilayer interference filter disposed at an input or output side of the optical amplifier or therebetween. The dielectric multilayer interference filter is stable over a wide band and exhibits a steep cut-off characteristic. The multi-cavity type dielectric multilayer interference filter has a center wavelength for transmission which is variable.
