Abstract
An optical device for modulating optical signals in a wavelength division multiplexed communication system. The device includes a plurality of phase modulators. Each of the phase modulators is configured to provide an associated phase modulated optical signal. Each of a plurality of optical filters receives an associated one of the optical signals and is configured to amplitude modulate the optical signal as an optical filter output signal. The optical filter output signals may be combined onto an aggregate path to a receiver including receiver optical filters for selecting the transmitted channels.
