(3)DGIST MEMS-based ultra-low power implementation
(4)High-speed, large-scale computations such as AI quantum computers are possible
(5)A new concept of optical-GPU has been developed that enables ultra-fast and high-efficiency calculations by reducing standby power to less than 1 million times. It is expected to be used in ultra-fast and low-power optical mining devices such as AI and quantum computers and optical integration circuits of quantum communication
(6)Daegu Gyeongbuk Institute of Science and Technology DGIST announced on the 9th that Professor Han Sang-yoon’s research team developed a light-powered light-GPU with Professor Yoo Kyung-sik of KAIST
(7)Optical-GPU is a technology that uses light to implement hundreds of virtual GPUs into one GPU Conventional optical-GPUs were difficult to commercialize due to severe heat problems with temperatures rising to hundreds of degrees

(1)The research team is a variable optical integration that is a unit component of optical-GPU
(2)By applying MEMS microelectromechanical system technology to circuits, standby power consumption was reduced to less than 1 million times compared to the previous one to solve the heat generation problem A variable optical coupler and a phase transducer are implemented based on ultra-low power MEMS
(3)The research team explained that this technology is also compatible with existing silicon-based optical integration circuits
(4)Professor Han Sang-yoon said, “For the first time in the world, we have achieved innovative results through a shift in the idea of incorporating MEMS technology into optical-GPU,” adding, “We expect it to be used in ultra-large AI models and quantum computers in the future.”
(5)The findings were published last month in Nature Photonics, an international journal in the field of optical engineering
