The aim of this paper is to provide a comprehensive review of mode-division and spatial-
division optical fiber sensors, mainly encompassing interferometers and advanced fiber …

Active control of sound and vibration is a relatively new and fast growing field of research
and application. The numbers of papers published on the subject have been more than …

The modal group delays (GDs) are a key property governing the dispersion of signals
propagating in a multimode fiber (MMF). An MMF is in the strong-coupling regime when the …

An apparatus utilizes a two-mode optical waveguide with a non-circular core to provide
stable spatial inten sity patterns in both propagation modes for light propa gating therein …

Optical fiber sensors are of particular interest for applications in the high-voltage
environments of the electric power industry due to their characteristic properties including a …

In the process of stimulated Brillouin scattering (SBS), acoustic waves are generated by the
interference of counterpropagating optical waves via electrostriction effect. These acoustic …

Few-mode fibers (FMFs) have found applications in optical communications and sensors
with attractive features that standard single mode fiber (SSMF) do not possess. We report …

Higher order spatial modes in optical fibers exhibit large, negative chromatic dispersion
when operated near their cutoff wavelength. By using a spatial mode-converter to selectively …

Reception of Mode and Polarization Multiplexed 107-Gb/s CO- OFDM Signal over a Two-Mode
Fiber Page 1 Reception of Mode and Polarization Multiplexed 107-Gb/s COOFDM Signal over …

We propose a unique few-mode fiber (FMF)-based multi-parameter optical-fiber sensor for
distributed measurement of temperature and strain. We launch a pump and a probe signal …
