Two fiber Raman probes are presented, one based on an optically-poled double-clad fiber
and the second based on an optically-poled double-clad fiber coupler respectively. Optical …

Second-harmonic generation (SHG) in double-anode thermally poled fibers is numerically
investigated. The poling process is investigated based on a two-dimensional charge …

Second-harmonic generation (SHG) near ultraviolet wavelengths is experimentally
demonstrated by coupling femtosecond pump pulses into the normal dispersion region far …

We report the real-time evolution of the second-order nonlinearity χ^(2) induced in a twin-
hole fiber during its first thermal poling and the subsequent repoling after thermal erasure …

Исследована генерация второй гармоники (ГВГ) в полностью волоконной схеме с
накачкой непрерывным иттербиевым лазером в много-и одночастотном режимах. В …

Entanglement is a property of quantum mechanics that confounds both physicists and
laymen alike, but has found practical applications in secure communications and metrology …

Second-harmonic generation (SHG) from a twin-hole fiber by thermal poling was studied.
Quasi-phase-matching (QPM) was performed with a low-pressure mercury lamp. Erasure of …

A comparison is made between DC-induced three-wave mixing under an on–off quasi-
phase-matching scheme and a perfectly phase-matched four wave mixing process. It is …

We demonstrate that second harmonic generation obtained in Ge-doped holey fibres can
act as a seed for visible supercontinuum generation. This spectral enlargement is obtained …
