Tunable optical filters

Tunable optical filters

dmf300 MicroFilter, an electronically tunable optical filter, provides better than 25-GHz wavelength stability, <0.1% wavelength scan nonlinearity, <0.5-dB insertion-loss variation, -40-dB typical return loss, <1-msec random-access channel selection and 0.1-dB polarization dependence. This Fabry-Perot filter operates at 1550 nm; a 1300-nm version is optional.
