Hackaday will launch cool projects that may stimulate others to expand and enhance it, and even move in a completely new direction. This is the way the most advanced technology continues to evolve. This DIY spectrometer project is a great example of this spirit. It comes from Michael Prathofer, who was inspired by Les Wright's PySpectrometer, a simple device pieced together by a pocket spectrom...
Strong field quantum optics is a rapidly emerging research topic that integrates nonlinear optoelectronic emission elements rooted in strong field physics with the mature field of quantum optics. Although the distribution of light particles (i.e. photons) has been widely recorded in both classical and non classical light sources, the impact of this distribution on the photoelectric emission proces...
Since the 1960s, lasers have brought revolutionary changes to the world and have now become an indispensable tool in modern applications, from cutting-edge surgical procedures and precision manufacturing to fiber optic data transmission. However, with the increasing demand for laser applications, challenges have also arisen. For example, the market for fiber lasers is constantly expanding, mainly ...
Us researchers report 8.1 μm wavelength quantum cascade laser (QCL) grown on silicon (Si) by MOCVD [S. Xu et al., Applications. Physics Letters, v123, p031110, 2023]. "There are no previous reports of QCL growth on silicon substrates by metal-organic chemical vapor deposition (MOCVD)," commented the team from the University of Wisconsin-Madison, the University of Illinois at Urbana-Champaign an...
