On October 3rd, the 2023 Nobel Prize in Physics was announced, recognizing scientists who have studied attosecond physics, marking the beginning of the attosecond era for humanity.At present, China's first attosecond laser device, the "Advanced attosecond Laser Facility", is being prepared and built in Dongguan, Guangdong, providing strong impetus for breakthroughs in multiple major basic scientif...
The nanoelectronics research center IMEC from Belgium announced the successful completion of a significant trial: the fabrication of a 110GHz C-band GeSi electro-absorption modulator on a 300mm silicon photonics platform.Achieving a net data rate of 400Gb/s per lane and optimized for compactness, low latency, and high energy efficiency, imec says its modulator “establishes the foundation for next-...
Petrobras announced last week that it plans to use laser beams to measure wind speed and direction. The idea is that these data will be used to improve the operation of the wind turbines maintained by this state-owned company in North Rio Grande do.The total investment of the 2.0 version of this device reaches R $11.3 million, known as the offshore wind assessment remote buoy.This technology can a...
Recently, Aerotech Inc., a global leader in precision motion control and automation, launched the HexGen HEX150-125HL miniature hexapod motion platform, a six degree of freedom (DOF) precision positioning system. This compact and cost-effective hexapod sports platform has a base diameter of 150 millimeters and a nominal height of 125 millimeters. It can achieve a minimum incremental movement of up...
