    Abstract: A broadband light source that outputs broadband light with reduced peak power includes a pulsed light source, an optical fiber, a band-elimination filter, and a light echo unit. The optical fiber receives pulsed light output from the pulsed light source, expands the spectrum of the pulsed light by a nonlinear optical effect within the fiber to generate supercontinuum light, and outputs the supercontinuum light. The light echo unit has a plurality of optical paths between an input terminal and an output terminal thereof. At least one optical path in the plurality of optical paths serves as a loop optical path. The light echo unit receives, via the input terminal, the supercontinuum light output from the optical fiber and having traveled through the band-elimination filter, guides the supercontinuum light through the plurality of optical paths, and outputs the supercontinuum light guided by the plurality of optical paths from the output terminal.

    Abstract: An apparatus and method are provided for filtering an optical signal by wavelength. An initially polarised signal is passed through a DGD element effective to alter the polarisation state of the components of the signal according to wavelength. A polarisation filter (polariser) is then provided to attenuate light having given polarisation states from the signal, thereby attenuating the wavelengths associated with said polarisation states. The invention finds particularly utility in the domain of vestigial sideband filtering, allowing the bandwidth of signals within a wavelength division multiplexed system to be reduced without introducing the deleterious effects associated with conventional wavelength filters.

    Abstract: A programmable, ultrafast optical delay line based on reversible frequency conversion uses a time-prism pair and no moving parts. A first electro-optic phase modulator acting as a first time-prism shifts the frequency of an incoming pulse train. The pulse train passes through a dispersion element, such as a dispersive fiber, which delays the pulse train by an amount that is directly proportional to the magnitude of the frequency shift, which in turn is proportional to the magnitude of the phase modulator drive voltage. A second electro-optic phase modulator is driven π out of phase to the first modulator and restores the frequency of the delayed pulse train to the original frequency of the incoming pulse train. To reduce pulse broadening effects and enhance performance further, soliton propagation inducing elements can be employed between the time-prisms.
