Effects of Spatially Nonuniform Gain on Lasing Modes in Weakly Scattering Random Systems
Jonathan Andreasen, Christian Vanneste, Li Ge +1
A study on the effects of optical gain nonuniformly distributed in one-dimensional random systems is presented. It is demonstrated numerically that even without gain saturation and…
Creation of New Lasing Modes with Spatially Nonuniform Gain
Jonathan Andreasen, Hui Cao
We report on the creation of new lasing modes with spatially nonuniform distributions of optical gain in a one-dimensional random structure. It is demonstrated numerically that eve…
Marginally Unstable Periodic Orbits in Semiclassical Mushroom Billiards
Jonathan Andreasen, Hui Cao, Jan Wiersig +1
Optical mushroom shaped billiards offer a unique opportunity to isolate and study non-dispersive, marginally unstable periodic orbits. Here we show that the openness of the cavity…
Finite-difference time-domain formulation of stochastic noise in macroscopic atomic systems
Jonathan Andreasen, Hui Cao
A numerical model based on the finite-difference time-domain method is developed to simulate fluctuations which accompany the dephasing of atomic polarization and the decay of exci…
