Universal single-mode lasing in fully chaotic two-dimensional microcavity lasers under continuous-wave operation with large pumping power
Takahisa Harayama, Satoshi Sunada, Susumu Shinohara
For a fully chaotic two-dimensional (2D) microcavity laser, we present a theory that guarantees both the existence of a stable single-mode lasing state and the nonexistence of a st…
Self-adjustment of a nonlinear lasing mode to a pumped area in a two-dimensional microcavity
Yuta Kawashima, Susumu Shinohara, Satoshi Sunada +1
We numerically performed wave dynamical simulations based on the Maxwell-Bloch (MB) model for a quadrupole-deformed microcavity laser with spatially selective pumping. We demonstra…
Chaotic laser based physical random bit streaming system with a computer application interface
Susumu Shinohara, Kenichi Arai, Peter Davis +2
We demonstrate a random bit streaming system that uses a chaotic laser as its physical entropy source. By performing real-time bit manipulation for bias reduction, we were able to…
Long-path formation in a deformed microdisk laser
Susumu Shinohara, Takehiro Fukushima, Satoshi Sunada +2
An asymmetric resonant cavity can be used to form a path that is much longer than the cavity size. We demonstrate this capability for a deformed microdisk equipped with two linear…
Signature of Wave Chaos in Spectral Characteristics of Microcavity Lasers
Satoshi Sunada, Susumu Shinohara, Takehiro Fukushima +1
We report the spectral characteristics of fully chaotic and non-chaotic microcavity lasers under continuous-wave operating conditions. It is found that fully chaotic microcavity la…
Experimental Observation of Resonance-Assisted Tunneling
Stefan Gehler, Steffen Löck, Susumu Shinohara +4
We present the first experimental observation of resonance-assisted tunneling, a wave phenomenon, where regular-to-chaotic tunneling is strongly enhanced by the presence of a class…
