Optically programable quasi phase matching in four-wave mixing [PDF]
Quasi-phase matching (QPM) enhances nonlinear optical processes by compensating for phase mismatch, but traditional methods require permanent material modifications, limiting applicability in centrosymmetric media like standard optical fibers.

Hollow-core pear-shaped conjoined-tube fiber with low loss in the ultraviolet band
PCTF (pear-shaped conjoined-tube fiber) is presented as a new ultraviolet (UV) guiding fiber with low loss. Results indicate that two PCTFs have better properties than that of previous studies in the UV band. The total loss of two PCTFs is less than 1 dB/

Chalcogenide Taper and Its Nonlinear Effects and Sensing Applications
The nonlinear coefficient of chalcogenide glass is 200–1000 times larger than that of silica glass, and it is transparent in the 1–15 μm wavelength windows, which makes the nonlinear effects happen at much low power with a short length in near- and mid ...
