Engineers at the University of California at Berkeley said that they have found a way to grow nanolasers on a silicon surface.
The invention could lead to, if we believe the scientists, to a new class of much more efficient microprocessors.
Silicon has been known to be very deficient at generating light, which caused Berkeley engineers use another class of materials known as III-V semiconductors to create light-based components such as LEDs and lasers, even if there are substantial challenges: "Growing III-V semiconductor films on silicon is like forcing two in-congruent puzzle pieces together," said Roger Chen, a UC Berkeley graduate student. "It can be done, but the material gets damaged in the process."
