Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

We present rate equation model of a modified vertical surface-emitting laser with two optical-coupled active cavities (СС-VSCEL) and external optical channel. The model allows to determine all the relevant parameters – carrier densities, gains, and output powers – starting from two input parameters: the injection currents in each cavity taking into account the additional external photonic injection. The system of rate equations is solved for different operating regimes of the modified laser device. The results provided by the model shown that operating characteristics of CC-VCSEL greatly depend on the number of photons of the external injection.
