DESCRIPTION:Dr Ileana Benea Chelmus\nAbstract:\n\nThe mapping of high-freq
 uency waves onto optical and near-infrared light – a process called elec
 tro-optic transduction - has opened new avenues of broad strategic importa
 nce: in metrology and sensing of high-frequency waves or in high-speed con
 trol of light. Most past technologies are limited to radio frequencies. Te
 rahertz compatibility is anticipated to boost applications. On one hand si
 de\, terahertz signals can be utilized to control optical signals at ever 
 faster speeds. Such devices are the back-bone of active optics with applic
 ations in consumer electronics. On the other hand side\, the terahertz ban
 d is rich in spectroscopic information. Consequently\, terahertz signals c
 an carry information about gases\, plastics or water content e.g. as part 
 of the internet of things. A large variety of applications require combine
 d merits of high-speed compatibility up to the terahertz and sensitivity d
 own to quantum-level signals. However\, achieving such performance is stil
 l an outstanding challenge. In this talk\, I discuss promising integrated 
 photonic technologies from state-of-the art electro-optic materials that p
 rovide unique possibilities to engineer these combined merits at the nanos
 cale. Through their design\, they target both free-space and on-chip appli
 cations in metrology and high-speed control of light.\n\nBiography:\n\nDr.
  Ileana-Cristina Benea-Chelmus is a SNF Fellow and a Hans-Eggenberger fell
 ow at John A. Paulson School of Engineering and Applied Sciences at Harvar
 d University. Her current work focusses on hybrid silicon-organic flat opt
 ics that change their optical functionality by electro-optic transduction.
  In parallel\, over the last years\, she has been developing on-chip integ
 rated electro-optic devices that can be utilized for terahertz field metro
 logy. In this framework\, she has been exploring their performance down to
  the quantum level both experimentally and theoretically. Overall\, her po
 stdoctoral and doctoral work have received several recognitions from the H
 ans Eggenberger foundation\, as well as the European Physical Society and 
 the Swiss Physical Society. Aside from science\, she strives to contribute
  positively to the community she’s a part of\, e.g by serving on the Met
 amaterials Technical Group of OSA among other activities.
