Newphotodetectorsshandura optical fiber kutaurirana uye tekinoroji yekunzwa
Nekuenderera mberi kwesainzi uye tekinoroji, optical fiber communication masisitimu uye optical fiber sensing masisitimu ari kuchinja hupenyu hwedu. Chikumbiro chavo chakapinda mune ese ehupenyu hwezuva nezuva, kubva paInternet kutaurirana kusvika pakuongororwa kwekurapa, kubva kumaindasitiri otomatiki kuenda kutsvagiridzo yesainzi. Munguva pfupi yapfuura, rudzi rutsva rwephotodetectoryakashandura hurongwa hwose.
Iyi photodetector inobatanidza aPIN photodiodeuye yakaderera ruzha amplifier wedunhu repamusoro rekushandisa bandwidth uye yakaderera yekuisa kurasikirwa. Izvi zvinoreva kuti inokwanisa kutora chiratidzo chechiedza munguva pfupi uye kuchishandura kuva chiratidzo chemagetsi, nokudaro kuwana kukurumidza-kumhanya uye kunobudirira photoelectric kutendeuka.
Uye zvakare, iyo photodetector yekuona wavelength renji inovhara 300nm kusvika 2300nm, inovhara anenge ese anooneka uye infrared wavelengths. Ichi chivakwa chinoita kuti chigone kushandiswa mune dzakasiyana siyana dzakasiyana optical uye sensing masisitimu.
Iyo photodetector ine analog chiratidzo chekugadzirisa uye kusimudzira mabasa, ayo anogona kukwidziridza asina kusimba masaini masaini akakwana kuti aonekwe nechiridzwa munguva pfupi pfupi. Izvi zvinobvumira kuti iite basa rinokosha muminda yakadai se optical communication, spectral analysis, lidar nezvimwe zvakadaro.
Mukuwedzera pakuva nesimba, iyi photodetector yakachenjera zvikuru mukugadzira. Iyo goko rakagadzirirwa kudzivirira guruva uye electromagnetic kupindira, iyo inogona kunyatso chengetedza yemukati wedunhu kubva mukukanganiswa kwekunze. Panguva imwecheteyo, yayo SMA yekubuda interface inoita kuti zvive nyore kubatana nemimwe michina.
Zvakakodzera kutaura kuti goko reiyi photodetector rine gomba rakarukwa, kuitira kuti rigone kugadziriswa pachikuva chemaziso kana midziyo yekuedza, iyo inobatsira zvikuru kushanda kwekuedza.
Pakazere, iyi nyowani photodetector inosimudzira kune optical fiber yekutaurirana masisitimu uye optical fiber sensing masisitimu. Iyo yakakwira yekushanda bandwidth uye yakaderera yekuisa kurasikirwa inogonesa yakakwirira-kumhanya uye inoshanda photoelectric kutendeuka, uye yakafara wavelength renji uye yakakwirira kuwana inogonesa kuchinjika kune dzakasiyana siyana dzakasiyana dzekushandisa. Iyo yakanakisa dhizaini uye nyore kuisirwa kunowedzera zvakanyanya ruzivo rwemushandisi. Iko kuunzwa kweiyi photodetector pasina mubvunzo kuchasimudzira kuvandudzwa kweoptical fiber communication uye sensing tekinoroji, ichititungamira munyika itsva yechiedza.
