The graph shows four different single cavity (SC) filters with different bandwidths centered at a wavelength of 1565 nm. The SC is typically used in telecom applications for wavelength locking on the C- and L-band DWDM ITU grid. In general, single cavity etalon filters can be manufactured for any wavelength in the 350 to 2500 nm range with Full-Width Half Maximum (FWHM) from 0.02 to 10 nm or higher. For further information on single cavity filters, please contact us.
