Aperiodically poled silica fibers for bandwidth control of quasi-phase-matched second-harmonic generation.
Precise control of the bandwidth of quasi-phase-matched second-harmonic generation in silica fibers is realized through chirped-period poling. The bandwidth is expanded by a factor of 33 over a uniform-period poled fiber of the same interaction length.
