We report on a simple route to the efficient coupling of optical emission from strongly confining bare core CdTe quantum dots (QDs) to the eigenmodes of a micro-resonator. The quantum emitters are embedded into QD/polymer sandwich microdisk cavities.

The homogenization of light is widely applied in various industrial sectors. The uniform high power processing of large areas requires a high degree of homogeneity. Sophisticated beam transformation techniques are used to optimize the illumination of

Introduction: Cardiac amyloidosis (CA) and hypertrophic cardiomyopathy (HCM) are important differential diagnosis of left ventricular hypertrophy. The aim of this study was to investigate if three-dimensional (3D) speckle tracking-derived functional

Pyramidal micro-cavities represent a novel promising class of semiconductor optical cavities. In contrast to our previous approach based on pyramids sitting on distributed Bragg reflectors, we investigate reversed freestanding GaAs pyramids. The latt

We report on whispering gallery mode (WGM) resonators consisting of poly(methyl methacrylate) (PMMA) which are promising candidates for label-free biosensing applications. The optical modes in these resonators experience a wavelength shift when the r

We report on polymeric high-Q microresonators and a method for spatially selective functionalization. Furthermore we present coupled resonators exhibiting a higher bulk refractive index sensitivity than single resonators making them promising candida

The paper reports on lasing and sensing properties of poly(methyl methacrylate) (PMMA) microgoblet resonators doped with the laser dye Pyrromethene 597 (PM597). The evanescent field of the microgoblet lasers can be used for label-free detection of mo

We report on a method for a highly flexible arrangement of polymeric high-Q whispering gallery mode resonators. Parallel on-chip fabricated goblet resonators are detached from the substrate by bonding a gold wire to the field-free center of their pol
