Channel selective power control method for optical wavelength division multiplexed systems, involves establishing selection region in which resonant channel has increased power density with respect to non-resonant channels

摘要

A selection region in which a resonant established channel having increased power density with respect to non-resonant channels, is established. The resonant channel is attenuated to a desired amount by adjusting the properties of the selection region. Independent claims are included for: (1) Channel selective power control arrangement; and (2) Optical device.
