Second-harmonic generation in an optical fibre by self-written χ(2) grating
A mechanism for phase-matched generation or second-harmonic (SH) light in an optical fibre has been experimentally and theoretically studied. A weak non-phase-matched SH signal, created via the quadrupole polarisation, initiates the self-writing of an axially periodic pattern of colour centres which...
