Device for multi-wavelength and ultrafast optical pulse generation

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),
• whereby two spectral lobes are produced within the multi-wavelength-pulses,
• wherein a first spectral lobe is centered around a first wavelength,
• wherein a second spectral lobe is centered around a second wavelength,
• wherein the first hollow core optical fiber is an anti-resonant hollow core optical fiber.
