The advent of all‐optical modulation format conversion techniques has fundamentally reshaped modern optical communications. These techniques enable the direct manipulation of optical signals in their ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

This study proposes a novel method to accurately estimate modulation amplitude and determine spatial resolution in BOCDR without additional devices. Brillouin scattering is the phenomenon of the ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics.

A team of researchers from the Center for Research and Innovation in Metamaterials at the University of Exeter and the Laser Processing Group at the Institute of Optics have presented in the journal ...

Photonic computing represents not a radical departure from familiar territory, but rather a natural extension along the electromagnetic spectrum. The transition from gigahertz to hundreds of terahertz ...

Engineers built a nanoscale optical device that uses voltage to control light's phase and intensity, advancing quantum communication and compact optical technologies. The device, developed by ...

What's behind the IEEE 802.3cz Multi-Gigabit Glass Optical Fiber Automotive Ethernet standard. Optical vs. electrical links in automotive Ethernet. Details behind various compliance and conformance ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
