Nonlinear phenomena are often among the most interesting and fascinating phenomena in physics. Light-matter interaction represents a fundamental field of research, which is nowadays deeply exploring the quantum realm, thanks also to the great advances in nanofabrication techniques of the last twenty years. Optical resonators provide the ideal environment to enhance nonlinear optical phenomena. In particular, semiconductor-integrated photonic micro-cavities can offer a huge enhancement of the optical field compared to bulk material. This has driven lots of research efforts because of the interest both at the fundamental and applied level. In this talk, a few classical and quantum experiments of nonlinear emission of light from semiconductor-integrated photonic cavities will be presented. A novel type of hybrid metal/semiconductor micro-resonators without cavity will also be introduced, based on Tamm plasmon resonance. The effect of a 3D confinement of these modes on the polarisation of the laser emission will be shown. Finally, recent experimental results about the coupling between the Tamm plasmon and the surface plasmon resonance will be briefly discussed.
