Spectrum collapse in a seven-core fiber laser with wavelength-shifted fiber Bragg gratings: modeling and comparison with experiment

High Power Laser Science and Engineering
Multicore fiber is a prospective medium for high-power lasers. All-fiber cavities based on fiber Bragg gratings (FBGs) inscribed by femtosecond pulses in uncoupled cores generate beams independently at wavelengths defined by the individual FBG reflection.

Seeing at a distance with multicore fibers

Opto-Electronic Advances
Images and videos provide a wealth of information for people in production and life. Although most digital information is transmitted via optical fiber, the image acquisition and transmission processes still rely heavily on electronic circuits.

Design and analysis of multimode step-index multicore silica photonic crystal fibers for communication and sensing applications

Results in Optics
The increasing demand for bandwidth in optical fiber communication has accelerated the adoption of space-division multiplexing (SDM), while compact platforms capable of simultaneous multisolute sensing are also highly desirable.

Crosstalk Analysis of Heterogeneous Multicore Fibers Using Coupled-Mode Theory

IEEE Photonics Journal, 2017
Intercore crosstalk of heterogeneous multicore fiber is investigated based on coupled-mode theory. Random twisting model is used for estimating the crosstalk. The crosstalk of two kinds of fibers: triangular lattice 30-core fiber with four kinds of cores

Optical Networking Beyond WDM

IEEE Photonics Journal, 2012
Wavelength-division multiplexing (WDM) has been the workhorse of data networks, accommodating exponential traffic growth for two decades. Recently, however, progress in WDM capacity research has markedly slowed down as experiments are closely approaching

Fiber link stabilization with a multicore fiber amplifier

Optics Letters
We study the use of separate cores of a multicore erbium-doped fiber amplifier (MC-EDFA) in a noise-canceled link for ultrastable optical frequency transfer. We demonstrate fractional frequency instability of 5×10 −19 at 1000 s averaging time for the stabilized MC-EDFA alone and 1.4×10

A Multicore Fiber-Based Velocity Sensor

IEEE Photonics Journal
In some special working environments, such as high temperatures, strong electromagnetic fields, dark and narrow spaces, existing technologies such as laser doppler velocimetry (LDV) and high-speed photography velocimetry (HSP) cannot effectively measure ...
