Fiber optic gyroscope (FOG) plays a critical role in aerospace, marine transportation, geological exploration, and other fields because of its advantages of low cost and broad development prospects.

This paper proposes a novel model to attain high birefringence and low loss in a slotted core-based photonic crystal fiber (PCF) structure in THz regime. The performance of the proposed PCF has been ...

With this latest breakthrough, India’s quantum communications can now work in real-world combat zones, deserts, hillsides, ...

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and ...

The project also benefits from strong industry backing, with six partners contributing technical expertise and in-kind ...

In this paper, a fifth-order variable-coefficient nonlinear Schrödinger equation is investigated, which describes the propagation of the attosecond pulses in an optical fiber. Via the Hirota’s method ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

An invisible force has long eluded detection within the halls of the world’s most famous particle accelerator—until now.

Tiandu scientists successfully prototype lunar regolith 3D printer which uses a high-precision reflective concentrator to ...

An overview of nonlinearities in optical fibers starting from fundamental interactions to their application in optical communication systems will be presented. Advanced techniques to mitigate or to ...

With the exponential growth of global data traffic driven by AI, big-data analytics, and cloud computing, today's single-mode fiber (SMF) networks are ...

A Pittsburgh company is developing new tools to help utilities act faster during grid failures, like during April’s severe ...
