A configuration of multi/demultiplexer using a 4-port optical circulator and interference filters is presented. Owing to the circulator, interference filters for the signal separation can be set normal to the optical signal propagating direction. Demultiplexing operation for 3 wavelength-multiplexed signals, of which wavelength spacings are 1.8 and 4.9 nm, is experimentally confirmed.
