This paper reviews the state of research in resonantly enhanced nonlinearities in fibers
doped with an absorber, of interest for low-power all-optical switching. A mathematical …

Ultrafast optical spectroscopy delivers unparalleled insights into the dynamic response of
photoactive materials, including semiconducting, photonic and phase-change materials. The …

The erbium-doped lithium niobate on insulator (Er: LNOI) platform has great promise in the
application of telecommunication, microwave photonics, and quantum photonics, due to its …

A transient tunable Bragg reflection grating has been established in an erbium-doped fiber
amplifier by the effect of a standing wave produced by counterpropagating cw light. Less …

Experimental measurements are described characterizing the nonlinear index change over
the range from 500 to 1550 nm induced in an ytterbium (Yb/sup 3+/)-doped twin-core fiber …

The quality-of-transmission (QoT) degradation due to the dispersion effect in longer
lightpaths is higher than that of shorter lightpaths in a dispersion uncompensated network …

A novel measurement system provides determination of pump induced phase shifts in
erbium doped fibers with an accuracy of/spl sim//spl pi//20. Using this system, a systematical …

We report a theoretical and experimental study of the refractive index variation in a heavily
doped erbium silica fiber within the spectral range 1500–1580 nm under the pumping at the …

In a doped fiber, at wavelengths close to an absorption, the refractive index, and hence the
dispersion, is expected to be a strong function of wavelength, as described by the Kramers …

The transient response of the Z-scan signal ΔT (t) was used to investigate the nonlinearity of
ion doped solids. n 2 measurements in ruby and alexandrite were performed using an Ar+ …
