Purdue University researchers have developed a technology design for field effect transistors that incorporates lasers, which could yield better switching behavior for computers and devices than traditional field effect transistors.

The team says the blending of a quantum cascade laser and transistor technologies into one design concept will help integrated circuit manufacturers aiming to build smaller and more transistors per unit area.

The technology is designed to boost the speed, sensitivity, and battery life of computers, mobile phones, and other digital devices.

The device boasts a large on-current and a low off-current with a small subthreshold swing, enabling greater speed and energy savings. Combining or stacking several switching mechanisms that simultaneously turn the transistor on or off is key, and the team is striving to optimize the technology and the effectiveness of the design.
