High-power and highly directional semiconductor microcylinder lasers based on an optical resonator with deformed cross section are reported. In the favorable directions of the far-field, a power increase of up to three orders of magnitude over the conventional circularly symmetric lasers was obtained. A "bow-tie"-shaped resonance is responsible for the improved performance of the lasers in the higher range of deformations, in contrast to "whispering-gallery"-type modes of circular and weakly… 

High power quantum cascade lasers

We concentrate on recent exciting results on quantum cascade (QC) microlasers with "chaotic laser resonators" obtained by deforming the circular shape of a whispering gallery cylinder laser into a

Edge-emitting GaAs-Al0.45Ga0.55As quantum cascade microlasers with photonic crystal reflectors have been fabricated. The resonator length of 100 mum leads to a large free-pectral range of the

Chaotic waveguide-based resonators for microlasers

We propose the construction of highly directional emission microlasers using two-dimensional high-index semiconductor waveguides as open resonators. The prototype waveguide is formed by two collinear

A ray-optics model is developed to describe the spoiling of the high-Q (whispering gallery) modes of ring-shaped cavities as they are deformed from perfect circularity and the escaping light emerges in certain specific directions, which may be predicted.
