THz generation with photoconductive emitters with a low-noise GHz repetition rate laser
25 January 2022 • 4:40 PM - 5:00 PM PST | Room 103 (Level 1 South Lobby)
Abstract
We demonstrate THz generation with state-of-the-art iron doped InGaAs photoconductive emitters using a low-noise GHz repetition rate amplified femtosecond laser operating at a central wavelength of 1560 nm. We measure a maximum dynamic range of over 75 dB and a bandwidth of more than 3 THz using lock-in technique. This unique laser source combining low-noise and high repetition rate proves to be a promising alternative to the frequently used fiber lasers at 100 MHz.

Menhir Photonics AG (Switzerland)
Florian Emaury is the CEO and co-founder of Menhir Photonics (Glattbrugg, Switzerland), a company focusing on manufacturing low-noise gigahertz ultrafast lasers for applications bringing together the field of photonics and electronics. After graduating in 2010 from the Institute d’Optique Graduate School in Paris (MSc in Photonics/Physics), his career started with engineer experiences in Fianium (UK) and Coherent (CA, USA) before joining ETH Zürich to obtain a PhD in Physics in 2015 in the group of Prof. Ursula Keller. Since then, Florian is devoting to create business opportunities with femtosecond lasers. In May 2018, Florian co-founded Menhir Photonics to offer reliable and turnkey ultrafast lasers to its users.
