The generation of 236 mW of second-harmonic power in a 32-cm-long periodically poled
silica fiber, corresponding to an average conversion efficiency of 15.2±0.5%, is reported …

D-shape silica fibres have been periodically poled at an elevated temperature by applying
high voltage via a patterned electrode deposited on the plane side. The resulting nonlinear …

Optical microfibres have recently attracted much attention for nonlinear applications, due to
their tight modal confinement. Here, we report broadband third harmonic generation based …

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 show that germanium-doped graded-index multimode silica fibers can exhibit relatively
high conversion efficiencies (∼ 6.5%) for second-harmonic generation when excited at …

Experiments on frequency doubling of 1064 nm and 1053 nm radiation with non-phase-
matched and (close to) phase-matched germania-doped silica fibres are reported. The …

The formation of efficient holographic second-harmonic generators in high-birefringence
phosphorus-doped germanosilicate fibers is reported. The influence of optical polarization …

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 …
