Optomechanical refrigeration of electronic circuits

该项目旨在应用激光来降低电子电路的温度。其目的是极大地抑制电子噪声，并为未来的电信系统提供一类新的技术。通过开发将光、电场和振动限制在亚微米尺度的硅芯片上的新技术，将实现超低噪声放大器、时钟和射频接收器等设备，以及超高效光调制器。未来，这些技术可以减少能源消耗，提高电信网络的可靠性。它们可以提高卫星通信的范围，GPS对宇宙辐射的稳健性，以及雷达和声纳等监视系统的性能。

The project aims to apply laser light to reduce the temperature of electronic circuits. This aims to greatly suppress electronic noise, and enable a new class of technologies for future telecommunication systems. By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-efficient optical modulators. In future, these technologies could reduce energy consumption and improve reliability in telecommunication networks. They could improve the range of satellite communication, robustness of GPS against cosmic radiation, and performance of surveillance systems such as radar and sonar.
