Chips have become an important role in people's life and work, and society cannot develop without chip technology. Scientists are also continuously improving the application of chips in quantum technology.
In two new studies, researchers at the National Institute of Standards and Technology (NIST) recently dramatically improved the efficiency and power output of a series of chip-scale devices that can produce different colors of laser light while using the same input laser source.
Many quantum technologies, including miniature optical atomic clocks and future quantum computers, require simultaneous access to multiple, widely varying laser colors within a small spatial area. For example, all of the steps required for the design of atom-based quantum computing require up to six different laser colors, including preparing the atoms, cooling them, reading their energy states, and performing quantum logic operations.The specific color produced is determined by the size of the microresonator and the color of the input laser. Since many microresonators of slightly different sizes are produced during the fabrication process, the technique provides multiple output colors on a single chip, all of which use the same input laser.
