Abstract:
A multiwavelength laser generation device having a laser source, means for actively modelocking the source, and means for simultaneously generating tunable separate modelocked wavelengths from the laser source, the improvement comprising:means for simultaneously generating separate multiwavelength channels from the modelocked laser source, the source including light directed between a grating and a spectral filter; means for reflecting broadband signals between the grating and the spectral filter to generate over 20(twenty) separate modelocked wavelength channels the modelocked laser source; and means for wavelength division multiplexing the over 20(twenty) separate modelocked wavelength channels; means for time division multiplexing the over 20(twenty) separate modelocked wavelength channels; and means for combining the wavelength division multiplexing with the time division multiplexing wavelengths to increase transmission rates and to form an aggregate rate output from the combined wavelength division multiplexing and time division multiplexing wavelength division multiplexing.
