Experimental methods are presented for determining the thermal resistance of vertical-cavity surfaceemitting lasers (VCSELs) and the lateral electrical conductivity of their p-type semiconductor layers. A VCSEL structure was manufactured from III-As

The paper presents the first vertical-cavity surface-emitting lasers (VCSELs) designed, grown, processed and evaluated entirely in Poland. The lasers emit at »850 nm, which is the most commonly used wavelength for short-reach (

Semiconductor planar microcavities significantly enhance the interaction between light and matter and are thus crucial as a fundamental research platform for investigations of quantum information processing, quantum dynamics, and exciton-polariton ob

High Contrast Metastructures X.
Here we present how the monolithic high contrast grating (MHCG) mirror focuses light. The studied grating has a shape of a square with 300 micrometers side. The light focuses along one of the sides of the square. As a light source in our experiment w

Vertical-Cavity Surface-Emitting Lasers XXV.
We experimentally demonstrate and elucidate by numerical simulations that breaking circular symmetry of large apertures of vertical-cavity surface-emitting lasers (VCSELs) significantly enhances their emission properties by increasing the optical den

High Contrast Metastructures X.
High contrast gratings (HCGs) are diffraction gratings whose period is less than the wavelength of light, made of a material with a high refractive index. Monolithic HCGs (MHCGs) are made of the same material as the cladding. They can be made of almo

High Contrast Metastructures X.
Monolithic high contrast grating (MHCG) is a particular type of a grating where both substrate and grating bars are made of the same material, in our case this is GaAs. Here we present the numerical simulations of GaAs-based planar focusing MHCG mirr

Breaking the spatial symmetry in optical systems has become a key approach to the study of nonlinear dynamics, wave chaos, and non-Hermitian physics. Moreover, it enables tailoring of the spatiotemporal properties of such systems. Breaking the circul

Here, we describe in detail a procedure for the numerical design of planar focusing mirrors based on monolithic high contrast gratings. We put a special emphasis on the reconstruction of the hyperbolic phase of these mirrors and we conclude that the

High Contrast Metastructures IX.
We design and process more than 100 different 980 nm MHCG mirror designs, to determine optimal parameters for the use of the MHCGs as mirrors for VCSELs. We present measured power reflectance spectra and compare the results to our with numerical simu
