We Solve for X: Ehsan Afshari on low-cost terahertz

Problem: The terahertz range (300 GHz to 3 THz) is the last part of the electromagnetic spectrum that does not have an inexpensive, accessible technology to emit and detect the light.
Solution: Use a number of inexpensive and small CMOS chips that can work together to emit terahertz light above 1mW, enough to use for many interesting applications in medicine, imaging and communications.
Breakthrough technology that might make it possible: Ehsan and his team at Cornell use several technical tricks to trick CMOS chips to produce electromagnetic waves in the terahertz range.

Although more highly technical, this is one of the best videos in the current spat of Solve for X talks.

Great talk!

[@SeanLumly]

Very technical, but a hugely important development.

[@hankh825]

great idea. but I think it is still along the parallel line of standard cmos technology

[@ShahabVaziri]

despite his awesome persian accent i enjoyed the talk. the commercial applications should be interesting.

some machine learning meets multi spectrum sensory device application ideas: real time acoustics mapping for MR mixing: windfarms sites and wind data maps at nanometer scales, know all the birds and perfect blade pitch sync: map space junk at nanometer scales to create viable mapping for autonomous navigation

Soon my pc will ask me not to turn it off before it gets to watch the sun set.
