Efficient Lasing in MoS/WSe-Based Metasurfaces Enabled by Quasi-Dark Magnetic Dipole Resonance
Georgios Nousios, Thomas Christopoulos, Emmanouil E. Kriezis +1
The novel combination of a strongly-resonant optical metasurface with the MoS/WSe hetero-bilayer is proposed for efficient free-space lasing enabled by the enhanced couplin…
Can 2D materials enable passively -switched lasers in the nanoscale?
Thomas Christopoulos, Johanne Hizanidis, Georgios Nousios +2
Achieving compact on-chip pulsed lasers with attractive performance metrics and compatibility with the silicon photonics platform is an important, yet elusive, goal in contemporary…
Temporal coupled-mode theory in nonlinear resonant photonics: From basic principles to contemporary systems with 2D materials, dispersion, loss, and gain
Thomas Christopoulos, Odysseas Tsilipakos, Emmanouil E. Kriezis
Temporal coupled-mode theory (CMT) is an acclaimed and widely used theoretical framework for modeling the continuous wave (CW) response and temporal dynamics of any integrated or f…
Multimode non-Hermitian framework for third harmonic generation in nonlinear photonic systems comprising 2D materials
Thomas Christopoulos, Emmanouil E. Kriezis, Odysseas Tsilipakos
Resonant structures in modern nanophotonics are non-Hermitian (leaky and lossy), and support quasinormal modes. Moreover, contemporary cavities frequently include 2D materials to e…
Graphene optical nonlinearity: From the third-order to the non-perturbative electrodynamic regime
Alexandros Pitilakis, Emmanouil E. Kriezis
A non-perturbative model for graphene optical nonlinearity is developed for the study of ultrafast pulse propagation along a monolayer, as in the case of graphene-comprising nanoph…
Experimental demonstration of ultrathin broken-symmetry metasurfaces with controllably sharp resonant response
Odysseas Tsilipakos, Luca Maiolo, Francesco Maita +5
Symmetry-protected resonances can be made to couple with free space by introducing a small degree of geometric asymmetry, leading to controllably-sharp spectral response. Here, we…
