W. Zhang et al., Polarization synthesized optical transversal filter employing high birefringence fiber gratings, IEEE PHOTON, 13(5), 2001, pp. 523-525
Polarization synthesizing is introduced into a Bragg grating based optical
fiber transversal filter to realize incoherent operation. High birefringenc
e fiber Bragg gratings are used to produce an optical transversal filter wi
th tunable microwave frequency response and large free spectral range immun
e to optical coherent noise.
