ROF InGaAs Photondetector o lo'o fa'asolo fua le fa'ata'ita'iga tasi-photon

O lenei oloa o se compact near infrared free running single photon detector.The core device adopts InGaAs/lnP with domestic independent intellectual property rights.Compared with same products, APD has advanced technical indicators, reliability and integration, and can be used for asynchronous low light detection such as liDAR and fluorescence lifetime detection.Applications tuuina atu tau-effective solutions.
O lenei oloa e faʻaaogaina se APD faʻamatalaga le lelei e ausia ai le faʻavavevave o le avalanche ma le maualalo o le pisa eletise, maualuga le iloa lelei ma le maualalo o le pogisa e ala i le faʻaogaina o le eletise ma le vevela. Faatasi ai ma i latou, o le maualuga o le faʻaogaina o le 1550nm tasi photon o le> 35%; I le taimi nei, o le taimi jitter e mafai ona maualalo i le 80ps; Su'esu'e lelei. I le 15%, o le numera pogisa aupito maualalo o le 500 CPS, ma le pito maualalo pou meli o le 1% @ taimi oti 5 um; Saturation faitau fua faatatau e oo atu i le 4MCps@ oti taimi 250ns. E le gata i lea, mo faʻataʻitaʻiga faʻapitoa talosaga, faʻaituau lagolago, faʻailoga mataʻutia, taimi oti ma isi taʻiala o le faʻaogaina o le faʻaogaina o galuega e faʻamalosia ai le lelei o le suʻesuʻeina, fua faʻatatau o le saturation ma isi faʻailoga faʻapitoa; Lagolago taimi faaliliu numera (TDC) galuega tauave e mafai ona determined.To maua taimi faitau faamatalaga, lagolago taufetuli saoloto po o fafo faaosofia gating .Two faagaoioia modes e maua.
