Society of Optics Student Chapter SeminarTitle: Novel Techniques of External Cavity Control for Quantum Cascade LasersAbstract: Quantum Cascade Lasers (QCLs) are a useful source of mid-infrared laser radiation for spectroscopic applications. Since the invention of QCLs 30 years ago and the invention of QCL frequency combs approximately 10 years ago, the implementation of new technologies to better leverage QCL performance and improve the their control is an active area of research. One powerful technique to control QCLs is by external cavity (EC) optical feedback injection. In this method, photons emitted from a laser are subject to selection by an external cavity and are subsequently fed back to the laser to seed the generation of new photons. This talk will discuss two EC-QCL technologies: one which enables an ultra-broadband laser spectrometer for planetary science applications, and another which has allowed controlled harmonic comb generation in QCL frequency combs. To complement this technical talk, Nick will also provide remarks on his experiences in graduate school as an undergraduate alumni of CREOL.About the speaker: Nick Kosan received his Bachelor's degree at CREOL in 2019 (summa cum laude). Currently, he is a Ph.D candidate at Princeton University's Department of Electrical and Computer Engineering under the supervision of Professor Gerard Wysocki. Nick's doctoral studies are supported by the NASA Space Technology Graduate Research Opportunities fellowship. His research focuses on laser spectroscopy systems with both single mode and frequency comb QCLs. As a visiting scholar, Nick continued these research efforts at Southwest Research Institute and ETH Zurich. In addition to his research responsibilities, Nick serves as the Vice President of Internal Affairs of Princeton's Graduate Student Government.

The UCF [Mathematics Colloquium](https://sciences.ucf.edu/math/colloquium/), held every Monday from 3:30-4:30 p.m. in MSB 318, offers a diverse platform for research scholars, faculty, students, and industry experts to share and exchange ideas, fostering discussion and networking across various areas of mathematics.[Sarah Arpin](https://math.vt.edu/people/faculty/arpin-sarah.html), Virginia Tech Department of Mathematics assistant professor, will speak at this week's colloquium on supersingular elliptic curve isogeny graphs.Abstract: Underlying the security of isogeny-based cryptography are supersingular elliptic curve isogeny graphs. These expansive, well-mixing graphs encode rich geometric information about supersingular elliptic curves over finite fields. In this talk, we take an arithmetic-geometric perspective to explore various graph variants. Along the way, we will uncover how supersingular elliptic curves and their isogeny graphs naturally lend themselves to cryptographic applications.
