We review our recent advances in fiber optical parametric amplifiers: demonstrate Mach-Zehnder architecture for polarization-insensitive operation with improved noise figure and reduced nonlinear ...

Invisible to the untrained eye, DFOS technology turns standard fiber optic cables into long-range, high-resolution sensing ...

A novel side-opening grapefruit fiber-based SPR sensor is designed to realize simultaneous measurement of refractive index (RI) and temperature. The open section of the grapefruit fiber is coated with ...
