Abstract: There is described a method of fabricating an optical fiber device, the method comprising: positioning longitudinal portions of a plurality of optical fibers alongside each other in a given geometrical relationship, depositing liquid coating material around the longitudinal portions of the plurality of optical fibers; and the liquid coating material setting up around the longitudinal portions of the plurality of optical fibers thereby maintaining said given geometrical relationship along the longitudinal portions.

Abstract: The method generally has the steps of propagating a seed wave in an optical fiber; generating a wave of first order by stimulated Brillouin scattering of the seed wave in the optical fiber, the wave of first order having a frequency spectrally shifted from the seed wave and being backscattered from the seed wave; propagating the seed wave and the wave of first order in a feedback cavity thereby generating a plurality of waves of higher order, each wave of higher order being cascadely generated by the wave of previous order, each wave of higher order being backscattered and having a frequency spectrally shifted from its corresponding wave of previous order and forming a frequency comb with the seed wave and the wave of first order; the frequency comb generating optical pulses; and propagating the generated optical pulses out of the feedback cavity.
