In what has been described as the "first communication", Swedish researchers conducted 3D printed quartz glass micro optical devices on the tip of optical fibers. They said that this progress could lead to faster Internet and better connectivity, as well as innovations such as smaller sensors and imaging systems.Scientists from the KTH Royal Institute of Technology in Stockholm have stated that co...
In the vigorous development of contemporary technology, green laser has become a shining star in the field of electronics. Not only because of its excellent performance, but also because it brings infinite imagination and creative inspiration to creators. The use of green laser for PCB (Printed Circuit Board) and FPC (Flexible Printed Circuit Board) shape cutting has opened up a new artistic journ...
A project at Macquarie University has demonstrated a way to narrow the linewidth of a laser beam by a factor of over ten thousand.Published in APL Photonics, the technique offers a promising route toward ultra-narrow linewidth lasers for potential use in a wide range of pump-pulse systems.Laser linewidth measures how precisely a beam of light maintains its frequency and color purity, and narrow-li...
Photoacoustic tomography (PAT) is a novel hybrid medical imaging technique that enables precise imaging of biological tissue structures at different spatial scales. It has been widely used in various fields, including brain imaging, cancer detection, and cardiovascular disease diagnosis. However, due to limitations in data acquisition conditions, photoacoustic tomography systems typically can only...
After electronic integrated circuits (Eics), silicon (Si) photonics technology is expected to achieve photonic integrated circuits (PIC) with high density, advanced functions and portability. Although various silicon photonics fountifiers are rapidly developing PIC capabilities to enable mass production of modulators, photodetectors and, more recently, lasers, silicon PIC has not yet met the strin...
