Nonlinear Polarization Manipulation in Optical Fibers [PDF]

Frontiers in Optics 2015, 2015
We describe a phenomenon of self-organization of the light state-of-polarization in optical fibers based on a nonlinear cross-polarization interaction between an incident signal and its backward replica. Several proof-of-principles for telecom applications are reported.

Multimode nonlinear fiber optics, a spatiotemporal avenue

APL Photonics, 2019
We provide a perspective overview of the emerging field of nonlinear optics in multimode optical fibers. These fibers enable new methods for the ultrafast light-activated control of temporal, spatial, and spectral degrees of freedom of intense, pulsed ...

Nonlinear chalcogenide optical fiber couplers

Optics Express, 2022
We demonstrate chalcogenide optical fiber couplers with a power-dependent coupling coefficient. The couplers are designed and fabricated using an As2Se3 fiber and characterized at a wavelength of 1938 nm, leading to a critical power of 126 W, the lowest ever reported for any optical fiber coupler.

Polarization-Insensitive Phase-Transmultiplexing and Multicasting of CSRZ-OOK and 4 $\times$ RZ-BPSK to 4 $\times$ RZ-QPSK via XPM in a Birefringent PCF

IEEE Photonics Journal, 2014
By utilizing cross-phase modulation and birefringence, we demonstrated simultaneous polarization-insensitive phase-transmultiplexing and multicasting of a single 10-Gbaud CSRZ-OOK signal and 4 $\times$ 10-Gbaud RZ-BPSK signals to generate 4 $\times$ 10-

Spatial Beam Self-Cleaning in Tapered Yb-Doped GRIN Multimode Fiber With Decelerating Nonlinearity

IEEE Photonics Journal, 2020
We experimentally demonstrate spatial beam self-cleaning in an Yb-doped graded-index multimode fiber taper, both in passive and active configurations. The input laser beam at 1064 nm was injected for propagation from the small to the large core ...
