We have just acquired our new magneto-optic cryostat with terahertz spectroscopy integrated into the magnet bore. We’ve worked with engineers at Lakeshore Cryotronics to get this system, the first commercial version of its kind, installed here at Brown. We’re looking forward to many exciting new results. Please contact us with any questions.

Please join us at 1:30pm for refreshments before the seminar.
First signal obtained from tilted-pulse-front setup, imaged using a THz camera. Very promising progress!
Our results on focusing terahertz waves using a leaky-wave antenna with an engineered phase velocity gradient has been published in Optics Express. Thanks to former group member Bobby McKinney for following through on this and producing a very nice manuscript.
Jim Buckwalter from the Electrical and Computer Engineering Department at the University of California Santa Barbara will present a seminar entitled “Fracking for 5G: Reconfigurable RF and high-efficiency millimeter-wave circuit techniques for better spectrum usage”. The seminar will be on Friday December 4th at 11am in Barus & Holley 190.
David Cooke from the Department of Physics at McGill University will present a seminar on Thursday December 10 at noon in B&H190. The title of the talk will be “Multi-THz spectroscopy of ultrafast charge transport processes in materials“. Please join us.
Qing Hu from the MIT Department of Electrical Engineering and Computer Science will present a seminar entitled “Terahertz Laser Frequency Combs” on Monday November 16 at 2pm in Barus&Holley room 190 (coffee and cookies at 1:30). Please attend!
Our recent results on waveguide-based multiplexing have been published in Nature Photonics, and have gotten quite a bit of attention in the media, for example here and here and here and here and here and here, among others. Congratulations to Nick and the rest of the co-authors for a very nice result.
