Abstract: Recently, exploring chiral and topological effects in integrated photonic circuits has gained prominence and enabled many novel direction-dependant and robust controls over light-matter interaction in classical and quantum domains. In this talk, I will present some of the key insights from our recent invited perspectives on integrated topological photonics [1] and chiral quantum optics [2], discussing the latest developments and future opportunities in quantum-emitter-integrated nanophotonics platforms, particularly beyond the single/few particle limit. Next, I will present our latest works on demonstrations of the first topological frequency combs [3] and the first on-chip two-timescale mode-locking in lattices of 100s of coupled SiN ring resonators. Moreover, I will also present our demonstration of a subwavelength optical lattice in a 2D-material-integrated plasmonic lattice platform using a novel “non-local” pump-probe spectroscopy method and will discuss its advantages for addressing pump-noise rejection and thermal management compared to conventional pump-probe schemes [4].

Bio Dr. Mahmoud Jalali Mehrabad received his PhD in quantum optics as a University Prize Scholarship Fellow from the University of Sheffield, UK, in 2021, under the supervision of Profs. Maurice Skolnick, Mark Fox, and Luke Wilson. His PhD was focused on developing semiconductor topological quantum photonic integrated circuits, for the generation, transfer, and manipulation of light at the single photon limit on-chip, for which he was awarded the UK’s Rank Prize Award in 2021. He joined the Joint Quantum Institute at the University of Maryland in 2022 to work in Prof. Hafezi's Lab. His postdoc work is focused on the generation and manipulation of a new class of optical frequency combs on topological silicon nitride, on-chip chiral quantum optics with solid-state quantum emitters, and 2D-materials-integrated plasmonics.
