We demonstrate an active power stabilization of a Nd:YAG laser employing the optical ac-coupling scheme and derive its fundamental quantum limit. This limit is 3 dB better than the one encountered in traditional power stabilization schemes. In our experiment, the optical ac coupling improved the shot-noise-limited sensitivity of the stabilization photodetector by a factor of 11.2. With an indep...

The effect of optical radiation on a uniformly doped nanoscale FinFET considering quantum mechanical effects has been theoretically examined and analyzed. The device characteristics are obtained from the self-consistent solution of 3D Poisson-Schrödinger equation using interpolating wavelet method. To our best knowledge this is the first approach for the self-consistent solution to surface pote...

In this article, the quantum correlation measurement technique as a method of power noise monitoring is investigated. Its principal idea correlating two photodetector signals introduced and contrasted to conventional approach, which uses only single photodetector. We discuss how scheme can be used obtain information below shot detected beam also electronic dark individual photodetectors, both n...

In today’s rapid development of multiphase organic photodetectors(OPDs), research on inverted ternary OPDs is very necessary. Therefore, this paper innovatively proposes an photodetector(OPD) with a structure ITO/PEIE/PC $$_{61}$$ BM/P3HT: PCPDTBT/MoO $$_{3}$$ /Al. And the PEIE electron transport layer(ETL), which essential for structure, used to study effects different thicknesses. Different t...
