A new study by University of Illinois engineers found that in the transistor laser, a device for next - generation high - speed computing, the light and electrons spur one another on to faster switching speeds than any devices available.

This technology, the transistor laser, is the next - generation technology, and could be a hundred times faster.»

«Because of the switching path differences between coherent and incoherent cavity photon densities reacting with collector voltage modulation via Feng - Holonyak intra-cavity photon - assisted tunneling resulting in the collector voltage difference in switch - UP and switch - DOWN operations, the transistor laser bistability is realizable, controllable and usable,» Feng said.

Compared to prior investigations, which contained optical hysteresis in cavities containing nonlinear absorptive and dispersive gain media, the operation principles as physical processes and operating mechanisms in transistor laser electro - optical bistabilities are considerably different.

«The transistor laser has those plus a third output — a coherent photon beam,» which can be transmitted by fiber - optic line for speed - of - light processing.
