The mode coupling in multimode fiber Bragg gratings (MMFBGs) is analyzed by using the coupled-mode theory. The reflection spectra of MMFBGs excited by one mode and two modes are simulated. The results of the calculation show that MMFBGs hav......

Using a fiber Bragg grating (FBG) and a Fabry-Perot cavity composed of two fiber Bragg gratings (FBGFP) as its frequency-selective components, a type of single frequency all-fiber ring laser permits oscillation only on one longitudinal mode......

The first hyperpolarizabilities ('beta') of four azobenzene derivatives are measured via hyper-Rayleigh scattering (HRS) technique at 1064 nm. These compounds show weak absorbance at 532 nm and neglectable two-photon fluorescence (TPF). The......

The new chromophore molecules with nonlinear optical (NLO) properties were prepared by Knoevenagel condensation from diformyl calix[4]arene and isophorone derivatives in the presence of piperidine and acetic acid, respectively. In these chr......

Two-photon excited stimulated emission at ~617 nm has been achieved in an organic chromophore solution pumped at 1064 nm. The stimulated emission can be observed only in the forward and backward directions and is characterized by its high d......
