A DEVICE FOR MULTI-WAVELENGTH AND ULTRAFAST OPTICAL PULSE GENERATION

Disclosed is a device for multi-wavelength generation, comprising: a pulsed light source configured to emit a train of light-pulses, wherein each of the light-pulses are defined by a center wavelength having a first pulse duration and a first bandwidth, and a first hollow core optical fiber having a core diameter, d, wherein the first hollow core optical fiber is configured to spectrally broadening the train of light-pulses, thereby generating a train of multi-wavelength-pulses having a plurality of wavelengths, wherein the first hollow core optical fiber has a dispersion that is selected such that that the light-pulses are spectrally broadened by primarily self-phase modulation (SPM).
