We propose a mode-locked figure-eight fiber laser by utilizing an attenuation-imbalanced nonlinear optical loop mirror (AI-NOLM) for the first time. Stable self-starting passively mode-locked pulses as short as 296 fs are obtained. We have also confi

We propose an angular offset technique for launching optical signals into multimode fibers (MMFs) used in short distance optical fiber links. The signal is launched onto the angled facet of an MMF. The presented method shows better bandwidth enhancem

An efficient numerical modal calculation method for an axially symmetric optical fiber is presented using a numerical Galerkin's method. By decomposing the transverse electric field of a guided wave with Bessel functions of the first kind in cylindri

We present a reflectometric measurement scheme of group-velocity dispersion for an optical fiber, whose measurement range covers the entire band of optical communication from 1200 to 1700 nm in wavelength by using a wideband supercontinuum source. In

When optical pulses of temporal width less than or comparable to a detector's response time are used to interferometrically measure intensity-dependent phase shifts, it becomes necessary to use time-averaging protocols to deduce the material nonlinea

We have shown that very large nonlinear shifts ranging from π/4 to π/2 observed at relatively modest input intensities in single-crystal cored fibers of 4-( N , N -dimethylamino)-3-acetamidonitrobenzene (DAN) have their origin in the cascading of t
