Gd. Vanwiggeren et al., Axial rotation dependence of resonances in curved CO2-laser-induced long-period fibre gratings, ELECTR LETT, 36(16), 2000, pp. 1354-1355
The magnitude and wavelength of transmission resonances in curved CO2-laser
-induced long-period fibre gratings (LPFGs) are shown to exhibit a strong d
ependence on the axial rotational orientation of the LPFGs.
