Ultra-Wideband Multiwavelength Light Source Utilizing Rare Earth Doped Femtosecond Fiber Oscillator

Multiwavelength optical fiber refractive index profiling

Fourier transform spectroscopy and interference microscopy are combined to provide the world's first multi-wavelength optical fiber refractive index profile (RIP) measurements. The RIP and its spectral dependence are obtained with submicron spatial resolution across an octave stretching from about 500 nm to the 1 micron operating band of Yb-doped fiber lasers and amplifiers. In contrast to comm...

Multiwavelength erbium-doped fiber ring laser source with a hybrid gain medium

Erbium-doped fiber is a gain medium exhibiting homogeneous line broadening at room temperature, while a semiconductor optical amplifier has a dominant feature of inhomogeneous line broadening. In this work, a semiconductor optical amplifier is incorporated into the cavity of an erbium-doped fiber ring laser to form a hybrid gain medium. Theoretical analysis shows that such a gain medium support...

All-fiber Optical Parametric Oscillator

All-fiber optical parametric oscillator (FOPO) has received considerable attention throughout these years. In this paper, we review the basic theory—four wave mixing (FWM) in the optical fibers, which leads to the parametric amplification. Phase matching condition is then discussed, with emphasis on the phase matching near the zero dispersion wavelength. In the end, recent developments on FOPO ...

Linear Fractionally Damped Oscillator

The linearly damped oscillator equation is considered with the damping term generalized to a Caputo fractional derivative. The order of the derivative being considered is 0 ≤ v ≤ 1. At the lower end v 0 the equation represents an undamped oscillator and at the upper end v 1 the ordinary linearly damped oscillator equation is recovered. A solution is found analytically, and a comparison with the...
