Effects of asymmetric stiffness on parametric instabilities of rotor

This work deals with effects of asymmetric stiffness on the dynamic behaviour of the rotor system. The analysis is presented through an extended Lagrangian Hamiltonian mechanics on the asymmetric rotor system, where symmetries are broken in terms of the rotor stiffness. The complete dynamics of asymmetries of rotor system is investigated with a case study. In this work, a mathematical model is ...

Optical parametric oscillaton in 1D semiconductor microcavities

We present an experimental investigation of parametric scattering processes and optical parametric oscillations in wire shaped, one-dimensional semiconductor microcavities. Far field emission patterns and corresponding band dispersion are studied by polarization resolved measurements and power dependence measurements under resonant and non-resonant excitation. The multiplicity of the photonic b...

Multi-Turing instabilities in Fabry-Pérot resonators and discrete microcavities

Alan Turing's seminal analysis of morphogenesis [1] was ahead of its time and laid the foundations for a modern understanding of the origin of pattern and form in Nature. He discovered that when a class of reaction-diffusion system is sufficiently stressed, arbitrarily-small disturbances to its uniform states may give rise to spontaneous self-organization into a simple pattern whose dominant sc...
