Photodetector Kwa Laser Kuthamanga Ndi Kuthamanga Kwachangu

Kufotokozera Kwachidule:

Mawonekedwe azinthu za InGaAs ndi 900-1700nm, ndipo phokoso lochulukitsa ndilotsika kuposa la germanium material. Nthawi zambiri amagwiritsidwa ntchito ngati chigawo chochulukitsira ma diode a heterostructure. Zinthuzi ndizoyenera kulumikizana ndi ma fiber othamanga kwambiri, ndipo malonda afika pa liwiro la 10Gbit / s kapena kupitilira apo.

Mafotokozedwe Akatundu

Pakalipano, pali mitundu itatu yopondereza ya ma InGaAs APDs: kuponderezana kwapang'onopang'ono, kupondereza mwachangu komanso kuzindikira kwa zitseko. Kuponderezana kwapang'onopang'ono kumawonjezera nthawi yakufa kwa ma avalanche photodiodes ndipo kumachepetsa kwambiri kuchuluka kwa chowunikira, pomwe kuponderezana kogwira kumakhala kovuta kwambiri chifukwa dera lopondereza ndilovuta kwambiri ndipo kutsetsereka kwa siginecha kumakhala kosavuta kutulutsa. Njira yodziwira mageti ikugwiritsidwa ntchito pozindikira chithunzi chimodzi. Zogwiritsidwa ntchito kwambiri.

Ukadaulo wozindikira za chithunzi chimodzi utha kupititsa patsogolo kulondola komanso kuzindikira kwadongosolo. Munjira yolumikizirana ya laser danga, kulimba kwa gawo la kuwala kwa zochitika kumakhala kofooka kwambiri, pafupifupi kufika pamlingo wa photon. Chizindikiro chomwe chizindikiridwa ndi chithunzithunzi chazithunzi chidzasokonezedwa kapena kumizidwa ndi phokoso panthawiyi, pamene teknoloji yodziwira imodzi ya photon imagwiritsidwa ntchito Kuyeza chizindikiro cha kuwala kofooka kwambiri. Ukadaulo wozindikira wa chithunzi chimodzi chozikidwa pa ma inGaAs avalanche photodiodes ali ndi mawonekedwe otsika pambuyo pa kugunda, kunjenjemera kwakanthawi kochepa komanso kuwerengera kwakukulu.

Kusintha kwa laser kwatenga gawo lofunikira m'magawo ambiri monga kuwongolera mafakitale, kuyang'anira kutali kwankhondo ndi kulumikizana kwapamlengalenga chifukwa cha mawonekedwe ake olondola komanso othamanga, komanso kupita patsogolo kwaukadaulo wa optoelectronic. Pakati pawo, kuphatikiza paukadaulo waukadaulo woyambira ma pulse, njira zina zatsopano zosinthira zimaperekedwa nthawi zonse, monga ukadaulo wodziwikiratu wamtundu umodzi wotengera ma photon counting system, womwe umathandizira kuzindikira kwa siginecha imodzi ya fotoni ndikuletsa phokoso kuti liwongolere. dongosolo. kutalika kwangwiro. Pazithunzi zamtundu umodzi, nthawi ya jitter ya chojambulira chimodzi-photon ndi m'lifupi mwa laser pulse zimatsimikizira kulondola kwa dongosolo loyambira. M'zaka zaposachedwa, ma lasers amphamvu kwambiri a picosecond lasers apangidwa mofulumira, kotero kuti nthawi ya jitter ya single-photon detectors yakhala vuto lalikulu lomwe likukhudza kulondola kwa ndondomeko ya single-photon rangeing systems.
