Transmitting an optical signal with corresponding WDM and TDM channels

An optical signal transmitter, comprising:

• a laser configured to generate and transmit a narrow laser pulse comprised of a plurality of wavelength channels;
• a dispersion system coupled to the laser and configured to broaden the narrow laser pulse into a wide laser pulse comprised substantially of the plurality of wavelength channels;
• and
• a modulator coupled to the dispersion system and configured to receive the wide laser pulse and an electric modulation signal comprised of a plurality of time slot channels, modulate the wide laser pulse based on the electric modulation signal wherein the plurality of time slot channels in the electric modulation signal correspond to the plurality of wavelength channels in the wide laser pulse respectively, and transfer a modulated wide laser pulse.

An optical communication network, comprising:

• an optical fiber;
• an optical signal transmitter coupled to the optical fiber and configured to generate a narrow laser pulse comprised of a plurality of wavelength channels, broaden the narrow laser pulse into a wide laser pulse comprised substantially of the plurality of wavelength channels, modulate the wide laser pulse based on an electric modulation signal comprised of a plurality of time slot channels wherein the plurality of time slot channels in the electric modulation signal correspond to the plurality of wavelength channels in the wide laser pulse, and transfer a modulated wide laser pulse over the optical fiber;
• and
• a node coupled to the optical fiber and configured to receive the modulated wide laser pulse over the optical fiber and filter a first channel from the modulated wide laser pulse wherein the first channel represents a wavelength channel and a time slot channel.
