#Chinese researchers have unveiled a #radarsystem so advanced that it can track not one, but as many as ten #hypersonicmissiles simultaneously, each hurtling through the atmosphere at the incredible speed of #Mach20, twenty times the speed of sound. The innovation lies in the radar's use of "#lasers" to transmit information between key components at the speed of light. This approach overcomes the limitations of conventional radar systems, in which the movement of high-speed electrons can potentially damage circuit boards. By integrating #photonics, the new radar is able to generate and process more complex #microwave signals, enabling for the first time the precise measurement of objects at very high speeds.

What do atomic clocks have to do with "Quantum" and why should I care about them? Read on to find out. For the past 30 years or so, the general standard for precision timekeeping has been Microsemi’s 5071, a cesium based atomic clock with an average sales price (ASP) approaching $100,000.  At the upper limits of non-optical atomic clock performance is the hydrogen maser which has ~100x the precision of the 5071 but has an ASP nearing $400,000 and generally requires an isolated environment and needs to be operated and maintained by highly technical personnel. There is a major market opportunity for a company that can provide “maser-like” performance at 5071 or better pricing.  See the link below for the latest Quantum Leap write-up of the current state of play in atomic clocks. I expect we will begin seeing many new optical clocks coming to market in the next few years. https://lnkd.in/gAxWCWie Companies referenced: Vescent, Menlo Systems, Infleqtion, Microsemi Corporation, TOPTICA Photonics, OROLIA LIMITED, Excelitas Technologies Corp., Octave Photonics, Muquans (now Exail), Stanford Research Systems Inc., Tekron International, AOSense, Inc, Xairos, AccuBeat, Frequency Electronics, Inc., SpectraDynamics, Inc., Oscilloquartz SA

A platform for integrating tunable single photon emitters on large-scale photonic integrated circuits (PICs) is introduced here. By hybrid integration of InAs/InP chiplets with a state-of-the-art silicon-on-insulator (SOI) PIC, researchers have demonstrated scalable emission wavelength programmability with individual emitter resolution.

Results from a large-scale #stellarator simulation with Quanscient Allsolve In our previous #HTS webinar, Dr. Mika Lyly presented results from a simulation project conducted in collaboration with Proxima Fusion last year. The project included a mesh sensitivity analysis on a full-scale stellarator magnet assembly. This complex simulation involved 30 coils, with one coil modeled in detailed cable accuracy, resulting in a model with 317 million unknowns. As demonstrated again live in the webinar, this magnetostatic simulation was solved in under 10 minutes with Quanscient Allsolve. This project demonstrated the capability of Allsolve to handle large-scale simulations efficiently, enabling faster design and optimization cycles for complex systems like fusion reactors. Watch the video below for Dr. Lyly's in-depth explanation of the project. (Learn more about leveraging cloud computing in HTS design with in our upcoming webinar on Sep 26: https://lnkd.in/dNb5cMYM)

MEMS VOA module  MEMS VOA module is a device used to attenuate optical power. It is mainly used for index measurement of optical fiber systems, signal attenuation of short-distance communication systems, and system testing. The optical attenuator is a very important fiber optic passive device. It can attenuate the optical signal energy as expected according to the user’s requirements. It is often used to absorb or reflect the optical power margin, evaluate the loss of the system and various tests. . At present, this series of optical attenuators has been widely used in the field of optical communications. #xhphotoelectric #voa #MEMS #communication #telecommunications #photonics #optics #fiber Read more https://lnkd.in/eN4wNW8j
