Collaborative Innovation of Optical Fiber Communication, Optical Sensors, and Lasers: New Trends and Technologies

Topic Information

Dear Colleagues,

Driven by the rapid advancement of AI, 6G, and the industrial IoT, the development of optical fiber communication, optical sensors, and lasers—core pillars of the optoelectronic ecosystem—is evolving from an isolated process into a integrated network that involves deep collaborative innovation. Traditional standalone technologies struggle with bottlenecks, including limited communication bandwidth, inadequate sensing precision, and poor laser-system compatibility, thus failing to meet the demands for high-speed transmission, real-time perception, and efficient energy supply in emerging scenarios. This Topic focuses on synergistic technological breakthroughs and new trends in these three fields, aiming to gather original research and reviews on cutting-edge directions such as advanced optical fiber materials, high-sensitivity sensing-laser integration, intelligent optoelectronic systems, and cross-domain applications. It seeks to bridge academic innovation and industrial practice, accelerating the translation of novel technologies into solutions for communications, smart manufacturing, healthcare, and infrastructure, thereby empowering the upgrading of the global optoelectronic industry.

Laser frequency stabilization underpins precision metrology, optical atomic clocks, quantum optics, and laser spectroscopy. In recent years, field-programmable gate arrays (FPGAs) have become attractive for this task because signal generation, phase-sensitive detection, digital filtering, feedback control, lock monitoring, and automatic re-locking can be integrated on compact and reconfigurable platforms. This review examines recent progress in FPGA-based laser frequency stabilization from four linked perspectives: stabilization principles, digital implementation, system architecture, and intelligent control. We first summarize representative error-signal generation methods, including Pound–Drever–Hall locking, saturation absorption spectroscopy, frequency modulation spectroscopy, and modulation transfer spectroscopy. We then discuss the FPGA functions that determine practical performance, such as data acquisition, direct digital synthesis, digital demodulation, proportional-integral-derivative (PID)/infinite impulse response (IIR) filtering, latency management, and lock-state monitoring. Mixed-signal, all-digital, distributed, and machine-learning-assisted systems are compared to show how bandwidth, latency, stability, integration, cost, and automation are balanced in different designs. This review closes by identifying remaining challenges in analog-to-digital converter/digital-to-analog converter (ADC/DAC) resolution, converter noise, loop latency, actuator bandwidth, long-term robustness, and algorithm portability, and by outlining future directions toward low-latency, software-defined, and intelligent stabilization platforms.

The evolution of neutron scattering from reactor-based steady-state sources to high-power pulsed spallation sources has necessitated a paradigm shift in neutron optics. While pulsed sources offer high peak brilliance and energy-resolved measurements via the time-of-flight (TOF) technique, the intrinsic divergence and broad wavelength bandwidth of the incident beam pose significant challenges for focusing, particularly in the realm of very small-angle neutron scattering (VSANS, Q < 0.001 Å⁻¹). This review presents a comprehensive analysis of diverse focusing techniques, including converging multi-slit apertures, electrical and superconducting magnetic sextupole lenses, grazing-incidence focusing mirrors, compound refractive lenses with oscillation apertures, and a special multi-beam VSANS configuration. Special attention is given to the transition from permanent magnet systems to nested rotating sextupole permanent magnets (Nest-Rot-SPM) and modulated superconducting sextupoles (SSM), detailing the physical and engineering challenges involved. Furthermore, grazing-incidence reflective optics, notably toroidal Wolter mirrors, are discussed as an achromatic alternative. The integration of these technologies into world-leading pulsed neutron sources is reviewed to project the future landscape of extended Q-range coverage for SANS instruments. Full article
