Best of - How light can power higher speed computing

Delve into the possibilities of silicon photonics as a game-changer in chip manufacturing. This is a re-run of a show that Russ did with David Miller back in 2021. David is an electrical engineer, and works in the field of photonics. As he shares in this conversation, there’s great potential for the field of photonics to help solve the problems posed by an increasing demand for computing power. Silicon-chip computers are starting to hit fundamental limits, and advances in the field of photonics – technology that uses light waves – may be just the help we need. David’s research offers a bright spot as we look to a future that continuously demands more computing power.
