Phase‐matched second‐harmonic generation is reported in periodically poled optical fibers
for the first time. A periodic χ (2) was induced in optical fibers during phase‐matched …

We generated second-harmonic light from a single-mode fiber after a few minutes of
seeding with 532-nm harmonic light along with 1.064-μm pump light. This experiment …

Phase-matched electric-field-induced second-harmonic generation is demonstrated in
single-mode germania-doped silica fibers. A periodic second-order nonlinearity is induced …

We report on quasi-phase-matched frequency doubling to the blue in electric-held poled
optical fibers. An increase of a factor of/spl sim/10 in the conversion efficiency in comparison …

The letter examines the photoinduced model for explaining efficient second-harmonic
generation in glass fibers with inversion symmetry. We show that a critical pump power …

We have prepared an optical fiber that produces efficient (0.24%) second-harmonic
conversion by using mode-locked 1.064-μm laser pulses along with a harmonic seeding …

The second-harmonic dependence on the input fundamental light has been measured in
optical fibers having a χ^(2) induced by seeding. The results are explained with a model that …

We show theoretically and experimentally that twisting a birefringent periodically poled fiber
with an artificially induced χ^(2) results in second-harmonic phase-matchings that are not …

Fibers were prepared for second-harmonic generation by injecting a frequency-doubled
(seed) signal with the fundamental light from a Nd: YAG laser. The relative phase shift …
