M. Jablonski et al., Adjustable coupled two-cavity allpass filter for dispersion slope compensation of optical fibres, ELECTR LETT, 36(6), 2000, pp. 511-512
A novel adjustable coupled two-cavity allpass filter has been realised for
the dispersion slope compensation of optical fibres. The filter gives varia
ble compensation between -2.0 and -15.5ps(3) over a bandwidth between 3.6 a
nd 1.2nm, respectively. The filter performance agrees quite well with that
predicted by existing theory.
