ROF InGaAs Photondetector yubusa-ikora imwe ya foteri

Iki gicuruzwa ni compact hafi yubusa bwa infragre yubusa ikora ya fotone imwe.Ibikoresho byibanze bifata InGaAs / lnP hamwe nuburenganzira bwumutungo bwite wubwenge bwigenga. Ugereranije nibicuruzwa bisa, APD ifite ibipimo bya tekinike bigezweho, kwiringirwa no kwishyira hamwe, kandi birashobora gukoreshwa mugutahura urumuri ruto rudasanzwe nka liDAR hamwe na fluorescence gutahura ubuzima.Ibisabwa bitanga ibisubizo bitanga umusaruro.
Iki gicuruzwa gikoresha ibitekerezo bibi APD kugirango igere ku kuzimya inkubi y'umuyaga n’urusaku ruke rwa elegitoronike, gukora neza no kubara kwijimye mukoresheje ibikoresho bya elegitoroniki hamwe nubushyuhe. Muri byo, ubushobozi bwa detector ntarengwa bwa 1550nm fotone imwe ni> 35%; Muri iki gihe, igihe jitter irashobora kuba munsi ya 80ps; Gukora neza neza.Kuri 15%, byibuze ibara ryijimye ni 500 CPS, naho impanuka yanyuma yoherejwe ni 1% @ igihe cyapfuye 5 um; Igipimo cyo kubara cyuzuye kugeza kuri 4MCps @ igihe cyapfuye 250ns.Iyongeyeho, kubintu byihariye byo gusaba, gushyigikira kubogama, kugenzura ibipimo ntarengwa, igihe cyapfuye nibindi bipimo byimikorere yabakoresha kugirango ushimangire imikorere yo kumenya, igipimo cyo kubara cyuzuye nibindi bipimo byihariye; Shyigikira igihe cyo guhindura imibare (TDC) imikorere irashobora kugenwa.Kubona igihe cyo kubara amakuru, shyigikira kwiruka kubuntu cyangwa imbarutso yo hanze .Uburyo bubiri bwo gukora burahari.
