Abstract
A single-mode all-fibre wavelength-division multiplexer (periodic wavelength filter) exhibiting very narrow separations (¿1 nm) between adjacent pass- and stopbands has been fabricated. The wavelengths at which this device has stop- and passbands may be varied by means of an external electrical control while maintaining a nearly constant band separation. Stopband extinctions in excess of 20 dB are reported for band separations of ¿30nm.
