J. Capmany et al., Efficient sidelobe suppression by source power apodisation in fibre optic microwave filters composed of linearly chirped fibre grating by laser array, ELECTR LETT, 35(8), 1999, pp. 640-642
First results are provided on efficiently apodised RF filters based on line
arly chirped fibre gratings fed by laser arrays yielding sidelobe reduction
s of 10-20dB as compared to uniform (unapodised) filters.
