Nanolaser advances promise improved electronics
|
|
(Nanowerk News) Nanolasers could potentially provide the next big breakthrough to make computers and similar technologies operate faster and more reliably.
|
|
Lasers can give electronic devices more firepower for processing and computing functions. So the more lasers you can pack into devices, the better – thus the advantage of using the extremely tiny nanoscale lasers.
|
|
The drawback has been that the heat generated by the nanolasers made their use impractical. To counteract that heat required cooling – a lot of cooling – all the way down to more than 400 degrees below zero Fahrenheit.

|
But recently, Arizona State University electrical engineer Cun-Zheng Ning and his research team announced progress in developing nanolasers capable of operating effectively at room temperature and with lower energy consumption – further opening the possibility of using them in consumer electronics.

Ning is a professor in the School of Electrical, Computer and Energy Engineering, one of ASU’s Ira A. Fulton Schools of Engineering.
