Nonstationary Regime of Random Lasers
Jonathan Andreasen, Patrick Sebbah, Christian Vanneste
A numerical study is presented of one-dimensional and two-dimensional random lasers as a function of the pumping rate above the threshold for lasing. Depending on the leakiness of…
Approximate equivalence between guided modes in a low-contrast photonic bandgap fiber and Maxwell TM modes of a high-contrast two-dimensional photonic structure
Olivier Legrand, Laurent Labonté, Christian Vanneste
We present a formal analogy between the eigenvalue problem for guided scalar modes in a low-contrast photonic bandgap fiber and quasi-stationary TM modes of a two-dimensional (2D)…
Modes of Random Lasers
Jonathan Andreasen, Ara Asatryan, Lc Botten +8
In conventional lasers, the optical cavity that confines the photons also determines essential characteristics of the lasing modes such as wavelength, emission pattern, ... In rand…
