From 1 May to 23 May, the student chapter launched our new seminar platform “Student chapter forum,” with three sessions.
Dr. Luca Carletti, from Università degli Studi di Brescia in Italy, gave the first lecture of the forum on the first of May. His topic was ” Nonlinear nanophotonics driven by Mie type resonances in all-dielectric nanoresonators”.
On the same day, Ms. Natalia Morais, a PhD visiting student from Paris Diderot University in France, gave the second lecture on “High-contrast AlGaAs nonlinear integrated photonics”.
The second session on the eighth of May featured a lecture by Mr. Davide Rocco, a PhD visiting student from Università degli Studi di Brescia in Italy. His lecture was on the subject of “Linear and nonlinear nanophotonics in AlGaAs nanocylinders”.
The third session, on 23 May, began with a lecture by Mr. Valerio Flavio Gili, a PhD visiting student from Paris Diderot University in France, on the subject of “Nonlinear nanophotonics on AlGaAs-on-AlOx monolithic platform”.
Dr. Niccolo Somaschi from Quandela, France gave the final lecture on “Accelerating optical quantum technologies with quantum-dot based devices”.
The Student Chapter Forum aims at providing a platform for photonics students and early career researchers to scientifically interact. The Forum, under the new title of “Photonics Vitality”, will become an anual event as one of the key activities of our chapter.
As a part of the National Youth Science Forum program some bright high school students visited the Research School of Physics and Engineering at ANU on the 5th of January. To encourage them to pursue a bachelors degree in science the SPIE and OSA ANU student chapters organised some lectures on polarisation and diffraction.
Students were eager to apply what they learned in the lecturers, so they took a photo when a diffraction grating was placed in front of the camera too!
On the 15th September the ANU student chapter of the OSA hosted Prof. Mikhail Belkin, from the University of Texas at Austin, as an OSA travelling lecturer. In his talk on “Photonic devices based on quantum-engineered nonlinear metamaterials” he described how his group uses inter-sub-band transition semiconductor heterostructures to make practical photonic devices.
These devices have functionalities not available with any other technology. For example, he described how they developed terahertz semiconductor laser sources based on efficient intra-cavity nonlinear frequency mixing in quantum cascade lasers. He also discussed their ultrathin highly-nonlinear metasurfaces that can provide broadband focal-plane frequency up- and down-conversion in the near-mid-far-infrared with only mW-level of optical pumping. His talk attracted a broad interest across the school and generated many discussions.
