Impact of cavity geometry on microlaser dynamics

Kyungduk Kim, Stefan Bittner, Yuhao Jin +3

We experimentally investigate spatio-temporal lasing dynamics in semiconductor microcavities with various geometries, featuring integrable or chaotic ray dynamics. The classical ra…

Spatio-temporal lasing dynamics in a Limaçon-shaped microcavity

Kyungduk Kim, Stefan Bittner, Yuhao Jin +3

Limaçon-shaped microdisk lasers are promising on-chip light sources with low lasing threshold and unidirectional output. We conduct an experimental study on the lasing dynamics of…

Exploiting structural nonlinearity of a reconfigurable multiple-scattering system

Yaniv Eliezer, Ulrich Ruhrmair, Nils Wisiol +2

Nonlinear optics is a rapidly growing field that has found a wide range of applications. A major limitation, however, is the demand of high power, especially for high-order nonline…

Complex nonlinear dynamics of polarization and transverse modes in a broad-area VCSEL

Stefan Bittner, Marc Sciamanna

Lasers can exhibit nonlinear and chaotic dynamics driven by the interaction of multiple lasing modes, and investigating the different scenarios of mode competition and bifurcations…

Sensitive control of broad-area semiconductor lasers by cavity shape

Kyungduk Kim, Stefan Bittner, Yuhao Jin +5

The ray dynamics of optical cavities exhibits bifurcation points: special geometries at which ray trajectories switch abruptly between stable and unstable. A prominent example is t…

Möbius Strip Microlasers: a Testbed for Non-Euclidean Photonics

Yalei Song, Yann Monceaux, Stefan Bittner +9

We report on experiments with Möbius strip microlasers which were fabricated with high optical quality by direct laser writing. A Möbius strip, i.e., a band with a half twist, exhi…
