Ortel belongs to the Photonics Foundries group and has launched its latest innovative product - the 1786 1550 nm laser module, aimed at significantly improving optical sensing in various applications. This laser module is designed specifically for continuous wavelength operation and is a key component of systems that require coherent light sources for precise sensing in environments with fluctuati...
Recently, the research team of the Aerospace Laser Technology and System Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, reported for the first time a low repetition frequency full polarization maintaining 9-shaped cavity fiber laser at 915 nm. The relevant research results were published in Optics Express under the title "Low repetition rate 915 nm ...
Recently, the UK's national synchrotron "Diamond Light Source" announced an investment of nearly £ 520 million ($648.3 million) to implement three new flagship beam lines and upgrade existing beam lines. This comprehensive upgrade will be delivered by 2030.The Department for Science, Innovation, and Technology and the biomedical charity Wellcome jointly approved the facility upgrade project,...
Typically, for lasers in optical communication systems, waveguide designs are used to achieve a single transverse mode. By adjusting the thickness of the surrounding area of the cladding layer and the etching depth of the ridge in the ridge waveguide device, a single mode device can be obtained. The importance of lasers is reflected in the following aspects:A chip without ridge waveguide design an...
