Cavity optomechanics investigatesthe coupling between light and mechanical vibrations. This interaction enablesnot only the extremely precise readout of the motion of nanostructures, butalso allows the manipulation of the mechanical vibrational state of thesesystems via optical forces. These latter can be used to reduce the amplitude ofa resonator's Brownian motion, or, on the contrary, to amplify it until theself-oscillation regime is reached, in which the mechanical system oscillatesin a coherent fashion.
Over the past few years, imec hasdeveloped the OMUS optomechanical platform for the fabrication ofultra-sensitive optical microphones, in the context of photoacoustic imagingapplications. These devices exhibit large optomechanical coupling factors, whichgive rise to strong interactions between light and the system's mechanicaldegree of freedom, allowing to reach the self-oscillation regime under ambientconditions. Studying these nonlinear optomechanical phenomena will pave the wayfor the development of various applications such as the fabrication of resonantsensors, time references, and optical frequency combs, on a mature,CMOS-compatible technology platform.
The goal of this internship willbe to study theoretically and experimentally the self-oscillation regime ofoptomechanical microphones. To this end, the student will use the setupsavailable at imec to experimentally characterize these systems and will work onimproving the models currently available in the team to describe thesephenomena. An application in resonant detection will also be explored.
Type of internship: Master internship
Duration: Up to 1 year
Required educational background: Physics, Nanoscience & Nanotechnology, Electrotechnics/Electrical Engineering
University promotor: Jan Genoe (KU Leuven)
Supervising scientist(s): For further information or for application, please contact Fabrice-Roland Lamberti ([email protected])
The reference code for this position is 2026-INT-020. Mention this reference code in your application.
Imec allowance will be provided for students studying at a non-Belgian university.
Applications should include the following information:
Incomplete applications will not be considered.
