Rudzi rutsva rwemudziyo wekuona fotoinoona zviratidzo zvechiedza zvisina simba mubhendi re2μm
Munzvimbo dzakawanda dzemazuva ano dzekutsvaga kwesainzi uye mashandisirwo emaindasitiri, kubata nekunyatsoongorora zviratidzo zvechiedza zvisina simba kwagara kuri kiyi yekufambisa hunyanzvi hwetekinoroji. Kunyanya mubhendi repakati pe2-micron (μm), kutorwa kweminwe yemamorekuru egasi, hunhu hwema laser matsva, uye ruzivo rwakadzama rwematishu ehupenyu zvese zviri mukati mechiratidzo ichi chemaziso chinoita sechisina simba asi chine ruzivo rwakakura. Zvisinei, kuoma kubata chiratidzo chemaziso chisina simba, kudzvinyirira kupindira kwezvakatipoteredza, uye kuoma kukuru kwekubatanidzwa kwemasisitimu zvagara zviri zvipingamupinyi zvakavanzika mukutsvagisa kwesainzi uye mashandisirwo einjiniya.
Nhasi, tinokuunzirai chigadzirwa chinosangana nezvinodiwa zveapplication iyi, R-PR-1G type 2μm analog light detection photodetector, yakatsaurirwa kuva "dawner" mumunda wekuona masaini echiedza chepakati peinfrared.
Iyo R-PR-2μmmodule yekuona fotoinobatanidza neunyanzvi chigadzirwa chinokurumidzira zvikuruInGaAs photodetectorine amplifier ine ruzha rushoma, yakaita se "super sensory" yakagadzirirwa kuyera optical chaiyo. Kushanda kwayo kwakanaka kunoratidzwa muhuwandu hwemhinduro dzespectral dze900-2300nm, dzinogona kufukidza mabhendi akawanda epakati peinfrared. Ingava kunyudzwa kwemhando yemamorekuru emvura mumhepo kana mawavelengths akasiyana anoburitswa neTM-doped neHo fiber lasers, ese anogona kubatwa nemazvo.
Kwete izvozvo chete, module yeR-PR-2μm photodetector inozivikanwa nekuwedzera kwayo, kunzwa kwakanyanya uye kugona kwayo kupenya. Kunyangwe mapiko elaser epicosecond-level asina kusimba zvakanyanya anogona kuzivikanwa nayo, zvichiita kuti chiratidzo chisarasikirwa nekubuda. Panguva imwe chete, ruzha rwayo rushoma runoderedza kupindirana kwemashure, zvichipa vaongorori data rakachena uye rakavimbika. Module iyi ine chimiro chakamanikana, inokwanisa kudzivirira kupindirana kwemagetsi, uye inotsigira single-mode fiber kana free-space coupling input, pamwe neSMA connector output, iyo inobatsira zvikuru kubatanidzwa uye kuiswa. Chinonyanya kukosha kutaura ndechekuti inotsigirawo kugadzirisa zvinoenderana nezvinodiwa nevatengi. Semuenzaniso, nzvimbo yePIN tube yakavakirwa mukati me photosensitive ndeyekusarudza, ichiratidza mwero wayo wepamusoro wekuchinjika uye kuchinjika. Kunyangwe chiedza chiri chidiki, chinogona kuteverwa. Module yeR-PR-2μm photodetector inoita kuti chiedza chisingaonekwe chiri mukushanda chionekwe, chiyereke uye chishandiswe.
