Overcoming Phase Noise Challenges in Ultra-Narrow Linewidth Single-Frequency Fiber Lasers
Single-frequency fiber lasers with ultra-narrow linewidths (<1 kHz) are critical for applications such as coherent optical communications, high-precision metrology, and quantum sensing. However, one of the most significant challenges in achieving such narrow linewidths is suppressing phase noise, which can degrade laser performance. Sources of Phase Noise Phase noise in fiber lasers...

Optical Delay Lines in Quantum Key Distribution (QKD): Synchronization Challenges
Quantum Key Distribution (QKD) enables ultra-secure communication by leveraging the principles of quantum mechanics to exchange cryptographic keys. A critical component in many QKD systems is the optical delay line (ODL), which introduces precise time delays to synchronize photons or compensate for path-length differences. However, implementing ODLs in QKD presents several synchronization...
