Measurement-Adapted Eigentask Representations for Photon-Limited Optical Readout

Tianyang Chen, Mandar M. Sohoni, Saeed A. Khan +5

Optical readout in low-light imaging is fundamentally limited by measurement noise, including photon shot noise, detector noise, and quantization error. In this regime, downstream…

Efficient computation of coherent multimode instabilities in lasers using a spectral approach

Sara Kacmoli, Saeed A. Khan, Claire F. Gmachl +1

Coherent multimode instabilities are responsible for several phenomena of recent interest in semiconductor lasers, such as the generation of frequency combs and ultrashort pulses.…

Nonequilibrium gas-liquid transition in the driven-dissipative photonic lattice

M. Biondi, G. Blatter, H. E. Türeci +1

We study the nonequilibrium steady state of the driven-dissipative Bose-Hubbard model with Kerr nonlinearity. Employing a mean-field decoupling for the intercavity hopping , we…

Spectral method for efficient computation of time-dependent phenomena in complex lasers

O. Malik, K. G. Makris, H. E. Türeci

Studying time-dependent behavior in lasers is analytically difficult due to the saturating non-linearity inherent in the Maxwell-Bloch equations and numerically demanding because o…

Interaction-induced mode switching in steady-state microlasers

Li Ge, David Liu, Alexander Cerjan +5

We demonstrate that due to strong modal interactions through cross-gain saturation, the onset of a new lasing mode can switch off an existing mode via a negative power slope. In th…

Inverse Vernier Effects in Coupled Lasers

Li Ge, Hakan E. Tureci

In this report we study the Vernier effect in coupled laser systems consisting of two cavities. We show that depending on the nature of their coupling, not only can the "supermodes…

Enhancement of Laser Power Efficiency by Control of Spatial Hole Burning Interactions

Li Ge, Omer Malik, Hakan E. Tureci

The laser is an out-of-equilibrium nonlinear wave system where the interplay of the cavity geometry and nonlinear wave interactions, mediated by the gain medium, determines the sel…

Anomalous transient amplification of waves in non-normal photonic media

Konstantinos G. Makris, Li Ge, Hakan E. Tureci

Dissipation is a ubiquitous phenomenon in dynamical systems encountered in nature because no finite system is fully isolated from its environment. In optical systems, a key challen…

Reversing the Pump-Dependence of a Laser at an Exceptional Point

M. Brandstetter, M. Liertzer, C. Deutsch +6

When two resonant modes in a system with gain or loss coalesce in both their resonance position and their width, a so-called "Exceptional Point" occurs which acts as a source of no…

Antisymmetric PT-photonic structures with balanced positive and negative index materials

Li Ge, H. E. Tureci

We propose a new class of synthetic optical materials in which the refractive index satisfies $n(-\bx)=-n^*(\bx)$. We term such systems antisymmetric parity-time (APT) structures.…

Pump-induced Exceptional Points in Lasers

M. Liertzer, Li Ge, A. Cerjan +3

We demonstrate that the above-threshold behavior of a laser can be strongly affected by exceptional points which are induced by pumping the laser nonuniformly. At these singulariti…

Unconventional modes in lasers with spatially varying gain and loss

Li Ge, Y. D. Chong, S. Rotter +2

We discuss a class of lasing modes created by a spatially inhomogeneous gain profile. These lasing modes are "extra modes", in addition to, and very different from, conventional la…

Ab initio self-consistent laser theory and random lasers

Hakan E. Türeci, A. Douglas Stone, Li Ge +2

We review our recent work leading to steady-state solutions of the semiclassical (Maxwell-Bloch) equations of a laser. These are coupled non-linear partial differential equations i…

Quantitative Verification of Ab Initio Self-consistent Laser Theory

Li Ge, Robert J. Tandy, A. Douglas Stone +1

We generalize and test the recent "ab initio" self-consistent (AISC) time-independent semiclassical laser theory. This self-consistent formalism generates all the stationary lasing…

Supporting Online Material for "Strong Interactions in Multimode Random Lasers"

Hakan E. Türeci, Li Ge, Stefan Rotter +1

This preprint contains the Supporting Online Material for our paper ''Strong Interactions in Multimode Random Lasers'', Science 320, 643 (2008) (also available at: arXiv:0805.4496)…

Strong Interactions in Multimode Random Lasers

Hakan E. Türeci, Li Ge, Stefan Rotter +1

Unlike conventional lasers, diffusive random lasers (DRLs) have no resonator to trap light and no high-Q resonances to support lasing. Due to this lack of sharp resonances the DRL…

A Gaussian-optical Approach to Stable Periodic Orbit Resonances of Partially Chaotic Dielectric Micro-cavities

H. E. Tureci, H. G. L. Schwefel, E. E. Narimanov +1

The quasi-bound modes localized on stable periodic ray orbits of dielectric micro-cavities are constructed in the short-wavelength limit using the parabolic equation method. These…

Deviation from Snell's Law for Beams Transmitted Near the Critical Angle: Application to Microcavity Lasers

H. E. Tureci, A. D. Stone

We show that when a narrow beam is incident upon a dielectric interface near the critical angle for total internal reflection it will be transmitted into the far-field with an angu…

Fresnel filtering in lasing emission from scarred modes of wave-chaotic optical resonators

N. B. Rex, H. E. Tureci, H. G. L. Schwefel +2

We study lasing emission from asymmetric resonant cavity (ARC) GaN micro-lasers. By comparing far-field intensity patterns with images of the micro-laser we find that the lasing mo…
