E. Pawlowski et al., VARIABLE BANDWIDTH AND TUNABLE CENTER FREQUENCY FILTER USING TRANSVERSAL-FORM PROGRAMMABLE OPTICAL FILTER, Electronics Letters, 32(2), 1996, pp. 113-114
The authors report the realisation of an integrated-optic variable ban
dwidth and tunable centre frequency filter using a transversal-form pr
ogrammable optical filter with 32 taps. The bandwidth is varied from 4
4 to 84GHz with a fixed centre frequency. Also, the centre frequency i
s tuned over 105GHz with a fixed bandwidth.
