We report a realization of room temperature lasing threshold of 1 μW in GaInP microdisk containing a few self-aggregated InP/GaInP quantum dots (QDs) grown by metal-organic vapor phase epitaxy. InP/GaInP QD microdisk cavities emitting in the spectral range of 700–800 nm and having the size of ~2 μm, free spectral range of ~35 nm and quality factors Q ~ 4000 were formed by wet chemical etching. Low...
Selective properties of resonant quasi-optical systems with periodical multi-row structures in millimeter wavelength range are described. The possibility of selection fluctuations in the volume of open resonator using double-row periodic elements was shown in the experiment at 70–80 GHz. Advantages and possibility of control the energy characteristics of such structures are also described. The obtained...
A review of articles and monographs on metamaterials are fulfilled in this paper in order to summarize the main types of artificial composites, depending on a sign of a permittivity and permeability. The classification of basic metamaterial structures for microwave applications with their characteristic properties and features is offered. Main disadvantages of the first metamaterial structures and...
