Abstract

High efficiency in-fiber bandpass f ilters with arbitrary passband/stop-band combinations have been produced successfully with an UV postfabrication exposure technique in broadly chirped fiber gratings. By further concatenating such a bandpass f ilter with two additional chirped gratings we achieved a f inesse as high as 220 for a 36-nm stop band. This new approach exhibits great advantages in controlling precisely the profiles of bandpass f ilters in terms of stop-band width, transmission wavelength and linewidth, and spacing of passbands. © 1995, Optical Society of America.
