Gaussian beam injection into multimode fiber

Oscillating propagation and parametric instability of the partial

We investigate the input and propagation characteristics and geometric parametric instability of the partial Gaussian beam limited by the fiber face area in a graded-index multimode fiber.

Direct Gaussian to high-order Laguerre–Gauss beam

We report our observation of a direct transformation of a Gaussian-like laser beam, initially injected into the cladding of a graded-index multimode

Shaping the light amplified in a multimode fiber

We demonstrate that appropriate structuration of the input beam wavefront can shape the light amplified by a rare-earth-doped multimode fiber.

Direct Gaussian to high-order Laguerre–Gauss beam shaping in a

We report our observation of a direct transformation of a Gaussian-like laser beam, initially injected into the cladding of a graded-index multimode fiber (MMF), into a high-order...

coupling ratio of a gaussian beam injected in a multimode fiber

Calculation of the coupling ratio of a gaussian beam directly injected into a multimode fiber optic.

Coupling an elliptical Gaussian beam into a multimode step-index fiber

The power coupling efficiency of an elliptical-spot-size Gaussian beam into a multimode step-index fiber is derived using a full-wave analysis.

Multimode Beams – free space, waveguide, fiber, monochromatic

Such a beam may arise, for example, by launching light from a single-frequency laser into a multimode fiber, where the input beam profile is not matched to one particular fiber mode.

Vortex mode excitation in a multimode fiber by the Laguerre-Gaussian

The coupling of Laguerre-Gaussian (LG) vortex modes into the Bessel vortex modes in a multimode fiber was analyzed using the vector form of LG beams. A formula for estimating the

Controllable all-fiber mode selection using Laguerre–Gaussian beam

We propose three novel simulation schemes for excitation of the Linearly-Polarized (L P) modes. In first scheme, when the Laguerre–Gaussian (L G) beam with definite waist is entered into

Multimode Fiber Beam Profiles Lab Facts

In some applications, an alternative beam distribution such as a top hat or donut is desired instead of the inherent Gaussian distribution provided by typical optics. Here we investigated the effect of changing

Multimode Beams – free space, waveguide, fiber,

Such a beam may arise, for example, by launching light from a single-frequency laser into a multimode fiber, where the input beam profile is not matched to one
