ʻO ROF InGaAs Photondetector ka mea ʻike kiʻi kiʻi hoʻokahi

ʻO kēia huahana he compact near infrared free running single photon detector.The core device adopts InGaAs/lnP with domestic independent intellectual property rights.Compared with like products, APD has advanced technical indicators, reliability and integration, and can be used for asynchronous low light detection like liDAR and fluorescence lifetime detection.Applications provide cost-effective solutions.
Ke hoʻohana nei kēia huahana i ka APD manaʻo maikaʻi ʻole no ka hoʻokō ʻana i ka avalanche quenching wikiwiki a me ka leo uila haʻahaʻa, kiʻekiʻe ʻike pono a me ka helu ʻeleʻele haʻahaʻa ma o ka hoʻolālā ʻana i ka uila a me ka hoʻolālā wela. Ma waena o lākou, ʻoi aku ka maikaʻi o ka detector pono o 1550nm hoʻokahi photon he> 35%; I kēia manawa, hiki ke haʻahaʻa ka jitter manawa e like me 80ps; ʻO ka maikaʻi o ka mea ʻike. Ma 15%, ʻo ka helu ʻeleʻele liʻiliʻi he 500 CPS, a ʻo ka liʻiliʻi post pulse he 1%@ make manawa 5 um; Saturation helu helu a hiki i ka 4MCps@ make manawa 250ns. Eia kekahi, no nā hiʻohiʻona noiʻi kikoʻī, kākoʻo ʻia, ka paepae screening, ka manawa make a me nā ʻāpana ʻē aʻe o ka hana hoʻonohonoho mea hoʻohana e hoʻoikaika i ka pono ʻike, helu helu saturation a me nā hōʻailona kikoʻī ʻē aʻe; Hiki ke hoʻoholo i ka hana hoʻololi kikohoʻe manawa kākoʻo (TDC).
