Thermo-optical pulsing in semiconductor amplifiers is experimentally shown to correspond
to a very common excitable scenario (the van der Pol–Fitzhugh–Nagumo system). Self …

We demonstrate experimentally and theoretically the existence of canard orbits and
excitable quasiharmonic limit cycles in the thermo-optical dynamics of semiconductor optical …

Neurons communicate by brief bursts of spikes separated by silent phases and information
may be encoded into the burst duration or through the structure of the interspike intervals …

An efficient continuous-wave (CW) mid-infrared laser with a tunable wavelength range from
3 to 4.5 μm is demonstrated by using intracavity optical parametric oscillator (ICOPO). An …

We have observed transverse pattern formation in type-II continuous-wave triply resonant
optical parametric oscillators (OPOs). Different kinds of cavities with degenerate transverse …

Nonlinear phenomena in superconducting resonator circuits are of great significance in the
field of quantum technology. We observe thermal self-oscillations in a monolayer graphene …

Self-sustained pulsations in the output of an InAs quantum dot laser diode in the MHz range
are reported. The characteristics (shape, range, and frequency) are presented for the free …

Although deterministic chaos has been predicted to occur in the triply resonant optical
parametric oscillator (TROPO) 15 years ago, experimental evidence of chaotic behavior in …

The stimulated Raman scattering (SRS) from the Nd: YVO_4 gain medium is originally
employed to eliminate the self-pulsing effect from the intracavity optical parametric oscillator …

Apresentamos neste trabalho o projeto e a construção de um Oscilador Paramétrico Ótico
(OPO), demonstrando o caráter quântico da correlação de intensidade dos feixes sinal e …
