Every day, the need for high speed reliable data transmission increases more and more. One important option is the passive optical networks which use the optical fiber and provides high data rates and ...

As one of the cutting-edge research areas in modern physics, space-based gravitational wave detection aims at capturing gravitational wave signals in the mHz frequency band. A key technological ...

Optical Code Division Multiple Access (OCDMA) systems enable simultaneous transmission of multiple data streams over a shared optical medium by assigning each user a unique code sequence. Rather than ...

Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares.

Multiplexing, or muxing, is a way of sending multiple signals or streams of information over a communications link at the same time in the form of a single, complex signal. The goal is to enhance the ...

Quantum networks, systems consisting of multiple connected nodes or devices that can transmit quantum information to one another, have the potential to advance future communications. These networks ...
