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…
Massively parallel ultrafast random bit generation with a chip-scale laser
Kyungduk Kim, Stefan Bittner, Yongquan Zeng +4
Random numbers are widely used for information security, cryptography, stochastic modeling, and quantum simulations. Key technical challenges for physical random number generation…
Suppressing spatio-temporal lasing instabilities with wave-chaotic microcavities
Stefan Bittner, Stefano Guazzotti, Yongquan Zeng +7
Spatio-temporal instabilities are widespread phenomena resulting from complexity and nonlinearity. In broad-area edge-emitting semiconductor lasers, the nonlinear interactions of m…
Dynamical calculation of third harmonic generation in a semiconductor quantum well
Stefano Guazzotti, Andreas Pusch, Doris E. Reiter +1
Non-linear phenomena in optically excited semiconductor structures are of high interest. We here develop a model capable of studying the dynamics of the photoexcited carriers, incl…
