Low-Cost High-Sensitivity Strain and Temperature Sensing Using Graded-Index Multimode Fibers [PDF]
We report a low-loss, low-cost high-sensitivity all-fiber strain and temperature sensor based on mode interference in graded-index multimode fibers. Blueshifts with strain and temperature sensitivities of 18.6 pm/microstrain and 58.5 pm/°C have been ...

High-bandwidth graded-index polymer optical fiber [PDF]
High-bandwidth (2 GHz/spl middot/km) graded-index polymer optical fiber (GI POF) was successfully obtained by the new interfacial-gel polymerization technique in which the unreactive component was used in order to obtain the quadratic refractive-index distribution.

Intra-Cavity Raman Laser Operating at 1193 nm Based on Graded-Index Fiber
Nonlinear Raman frequency conversion is an important technical scheme to obtain special optical band lasers based on conventional ion-doped lasers. In our work, we designed an intra-cavity Raman fiber laser based on graded index fiber (GRIF) as the Raman

Femtosecond Soliton Erbium-Doped Fiber Laser With a Symmetrical GIMF–SIMF–GIMF Saturable Absorber
A femtosecond soliton erbium-doped fiber ring laser with the symmetrical saturable absorber (SA) of graded index multimode fiber-step index multimode fiber-graded index multimode fiber (GIMF-SIMF-GIMF) is proposed and proved.

Twist-Related Speckle Variation in Graded-Index Multimode Fiber
We theoretically investigate a twist-related speckle variation in a graded-index multimode fiber. The simulation results show that by increasing the offset splicing distance between a single-mode fiber and a multimode fiber, the speckle pattern tends to ...

Beam self-cleaning in multimode optical fibers and hydrodynamic 2D turbulence [PDF]
We experimentally demonstrate the conservation of the average mode number in the process of Kerr beam self-cleaning in a graded-index multimode optical fiber, in analogy with wave condensation in hydrodynamic 2D ...

Graded-index solitons in multimode fibers
We investigate stability of optical solitons in graded-index (GRIN) fibers by solving an effective nonlinear Schrödinger equation that includes spatial self-imaging effects through a length-dependent nonlinear parameter. We show that this equation can be reduced to the standard NLS equation for optical pulses whose dispersion length is much longer than

Orthogonal frequency-division multiplexing in wireless communication systems with multimode fiber feeds [PDF]
The feasibility of using multimode fiber as an inexpensive cell feed in broad-band indoor picocellular systems is investigated in this paper. The performance of coded orthogonal frequency-division multiplexing (OFDM) for a variety of multimode fiber ...

Cascaded Generation in Multimode Diode-Pumped Graded-Index Fiber Raman Lasers
We review our recent experimental results on the cascaded Raman conversion of highly multimode laser diode (LD) pump radiation into the first- and higher-order Stokes radiation in multimode graded-index fibers.
