In this contribution, we explore the generation of light in transformation-optical media. When charged particles move through a transformation-optical material with a speed larger than the phase velocity of light in the medium, Cherenkov light is emi

We study Veselago's lens with arbitrary index of refraction and characteristic impedance. Using a full wave optics calculation, we show that this lens can be considered as an imaging system and we derive the appropriate lens formula. The lens with ar

We report here on polarization dynamics in VCSELs subject to a time-delayed optical feedback from a short external cavity. We find the emergence of pulse packages exhibiting characteristics which originate from the interplay of time-delay induced dyn

From a linear stability analysis of the stationary solutions of a two-mode intensity rate equation model, we study the effects of nonlinear gain on the mode competition in vertical-cavity surface-emitting lasers. Our analysis explains recent experime

We present a rate equation model of a single mode vertical-cavity surface-emitting laser (VCSEL) with two states of linear polarization, subject to Doppler-shifted optical feedback. Recent experimental work has shown that the polarization bistability

We theoretically investigate polarization and intensity all-optical bi- and tri-stability in interference structures that include both a birefringent LiNbO3 layer of varying crystallographic orientation and an absorbing layer. The origin of this bi-

In high energy physics, unknown particles are identified by determining their mass from the Cherenkov radiation cone that is emitted as they pass through the detector apparatus. However, at higher particle momentum, the angle of the Cherenkov cone sa

The interaction between light and matter involves not only an energy transfer, but also the transfer of linear momentum. In everyday life applications this linear momentum of light is too small to play any significant role. However, in nanoscale dime
