Analysis of characteristics of InGaAs/GaAs microdisk lasers bonded onto silicon board
St. Petersburg Polytechnical University Journal: Physics and Mathematics. 2022. Vol. 15. No. 3.3. P. 163–166.
In this work we study characteristics of the III-V microdisk lasers bonded onto silicon board. The bonding of microdisk lasers to the silicon substrate reduces their thermal resistance. Here we show improvement in output power, lasing threshold, dynamic characteristics and energy consumption in microdisk lasers with diameters of 31 μm and 19 μm by comparison of the characteristics obtained before and after bonding. Also, estimation of energy-to-data ratio was performed at 13 °C and 20 °C for a 19 μm microdisk lasers after bonding.

Optical satellite communication uses laser radiation to transmit information instead of the classical
radio frequency range. Laser communication is characterized by better performance due to higher carrier
frequency and less power consumption. PIN, avalanche, and superconducting single-photon detectors
(SSPD) can be used to receive optical signals. In this paper, we describe an automatic optical power control
(AOPC) system that ...

A vast majority of electrical devices have integrated magnetic units, which generate constant magnetic fields with noticeable vibrations. The majority of existing nanogenerators acquire energy through friction/mechanical forces and most of these instances overlook acoustic vibrations and magnetic fields.
