PHOTOACOUSTIC SPECTROSCOPY GAS DETECTION TECHNOLOGY RESEARCH - Syropy AI Connectivity

Photoacoustic Spectroscopy Hydrogen Module

We present the design and modeling of a novel photoacoustic spectroscopy (PAS) sensor capable of detecting molecular hydrogen at parts-per-billion (ppb) concentrations in air. Here, we introduce conductance–photoacoustic spectroscopy (ConPAS), an integrated sensing approach that combines conductance-based resonance modulation with quartz-enhanced photoacoustic spectroscopy in a single device. In one experiment, 532 nm output of a seeded pulsed Nd:YAG laser is employed as Raman pump source and a Raman shifter filled with gaseous.

Research and Development of Optical Fiber and Cable Manufacturing Technology

In this article, we introduce the latest research and development (R&D) on optical fiber technology for access networks and for next-generation optical fiber networks.

Coupling technology of wavelength division multiplexers

This technique enables bidirectional communications over a single strand of fiber (also called wavelength-division duplexing) as well as multiplication of capacity.

New optoelectronic fusion technology for edge computing

We have proposed the Fourier domain diffraction neural network, constructed the reconfigurable diffraction computing processor (DPU), developed the all-analog optoelectronic fusion computing chip ACCEL, and the large-scale general-purpose intelligent optoelectronic computing . We present GENIO, a novel platform that integrates edge computing within existing Passive Optical Network (PON) infrastructures. Integrating microelectronics and optoelectronics can harness the mature processes and functions of microelectronics, with the ultra-wideband and low-power benefits of optoelectronics.

Fiber Optic Current Sensing Technology

A fiber-optic current sensor (FOCS) is a device designed to measure direct current. Explore pioneering discoveries, insightful ideas and new methods from leading researchers in the field. The Faraday effect is the rotation of the polarization state of light, β, when it passes through a magnetic field, B, induced by an.
