@article { , title = {Acousto-optical nanoscopy of buried photonic nanostructures}, abstract = {We develop a nanoscopy method with in-depth resolution for layered photonic devices. Photonics often requires tailored light field distributions for the optical modes used, and an exact knowledge of the geometry of a device is crucial to assess its performance. The presented acousto-optical nanoscopy method is based on the uniqueness of the light field distributions in photonic devices: for a given wavelength, we record the reflectivity modulation during the transit of a picosecond acoustic pulse. The temporal profile obtained can be linked to the internal light field distribution. From this information, a reverse-engineering procedure allows us to reconstruct the light field and the underlying photonic structure very precisely. We apply this method to the slow light mode of an AlAs/GaAs micropillar resonator and show its validity for the tailored experimental conditions.}, doi = {10.1364/OPTICA.4.000588}, eissn = {2334-2536}, issue = {6}, journal = {Optica}, publicationstatus = {Published}, publisher = {Optical Society of America}, url = {https://nottingham-repository.worktribe.com/output/862337}, volume = {4}, year = {2017}, author = {Czerniuk, T. and Schneider, C. and Kamp, M. and Höfling, S. and Glavin, B.A. and Yakovlev, D.R. and Akimov, Andrey V. and Bayer, M.} }
