We investigate dark counts in SNSPD with spatial resolution, using nanostrip-patterned devices with 50 Ohm matched coplanar waveguide - tapers. We found that the dark counts originate from one or several points along the strip, which we call 'weak points'. We found that the dark counts originating from different points can have different dependence of ...

We report on InGaAs/GaAs quantum dot injection microdisk lasers laterally connected with a bus waveguide fabricated by planar technology from the same epi-structure. Various coupling schemes of microlaser with waveguide are studied including a microlaser attached to a waveguide (zero gap), a 100 nm gap for evanescence light outcoupling, and with a waveguide surrounding the ...

Semiconductor lasers have developed rapidly with the steady growth of the global laser
market. The use of semiconductor laser diodes is currently considered to be the most advanced
option for achieving the optimal combination of efficiency, energy consumption, and cost parameters
of high-power solid-state and fiber lasers. In this work, an approach for optical mode engineering
in planar waveguides ...

The actual problem of accelerating and reducing the energy costs of the sheet polymer composite material heat treatment technological process is considered. It is shown that to solve this problem, it is advisable to use the microwave radiation energy as a heating source. The main advantages of the microwave method of the sheet polymer composite ...

Using numerical simulation, the search for designs of asymmetric barrier layers (ABLs) in a laser
diode with a GaAs waveguide emitting at a wavelength of λ = 980 nm is carried out. A pair of ABLs adjoining
the active region on both sides blocks undesired charge-carrier flows and suppresses parasitic spontaneous
recombination in the waveguide layers. Optimal designs ...

Features of the implementation of a beam-pulse amplifier (BPA) of whistler waves in magnetospheriс
enhanced and depleted ducts with refraction reflection are considered. Extended along the magnetic
field, ducts with a width of about 100–300 km often occur after magnetic disturbances in the morning and
daytime magnetospheres beyond the plasmapause, where the excitation of chorus emissions occurs under ...

This paper addresses the high-priority goal of reducing the energy cost of heat-treating foam concrete slabs. We show that this problem is best solved using microwaves as a heat source. We discuss the main advantages of microwave curing over traditional techniques for curing foam concrete slabs, and develop a design for a microwave foam concrete ...

Multi-chip embedded PCBs were in resent years the mainstream technology of electronic packaging size reduction and at the same time providing improved performance. Ultra-small package size obviously strongly impacts the SiP module thermal behaviour. Unfortunately the complete thermal design methodology was not developed for this technology till now. In this work the problem of thermal ...

A set of modified compact SPICE models of various flavours of MOSFETs (fabricated by bulk, SOI and SOS technologies) is presented for circuit simulation in the deep-cryogenic temperature range down to 4 K, which is important for space applications and development of scalable quantum computers. All models are constructed using the approach combining macromodeling based ...

A method for the construction of microwave devices with longitudinal interaction is proposed. Devices of the present type create uniform cross-sectional distribution of temperature of rods made of polymer composite materials. Results from theoretical and experimental investigations of the cross-sectional distribution of the temperature of the material of the rod as well as the parameters ...
