Ubwoko bushya bwa fotodetector bubona ibimenyetso by'urumuri bidakomeye mu gice cya 2μm

Ubwoko bushya bwaicyuma gipima fotoimenya ibimenyetso by'urumuri bidakomeye mu gice cya 2μm

Mu nzego nyinshi zigezweho z’ubushakashatsi bwa siyansi n’inganda, gufata no gusesengura neza ibimenyetso by’urumuri bidakomeye byagiye biba ingenzi mu guteza imbere udushya mu ikoranabuhanga. Cyane cyane mu gice cya mikoroni ebyiri (μm) hagati ya infrared, uburyo imiterere y’ibikumwe bya gazi, imiterere y’imitsi ya laser nshya, n’amakuru yimbitse y’uturemangingo tw’ibinyabuzima byose biri muri iki kimenyetso cy’urumuri gisa n’aho kidakomeye ariko gikungahaye ku makuru. Ariko, ingorane zo gufata ibimenyetso by’urumuri bidakomeye, gukumira ukwivanga kw’ibidukikije, hamwe n’uburyo buhanitse bwo guhuza sisitemu byagiye biba inzitizi zihishe mu bushakashatsi bwa siyansi no mu bikorwa by’ubuhanga.

Uyu munsi, turabagezaho ibicuruzwa byujuje ibisabwa n'iyi porogaramu, imashini ipima urumuri ya R-PR-1G yo mu bwoko bwa 2μm analog, yagenewe kuba "umuseke" mu bijyanye no kumenya ibimenyetso by'urumuri rwo hagati mu ntera ya infrared.

R-PR-2μmmodule y'icyuma gipima fotoihuza mu buryo bw'ubuhanga uburyo bworoshye bwo kongera imbaragaInGaAs foto detectorifite amplifier y'urusaku ruke, isa n'icyuma "cy'ibyiyumviro bidasanzwe" cyagenewe gupima neza optique. Imikorere yacyo ihebuje igaragarira mu buryo burambuye bwo gusubiza spectral bwa 900-2300nm, bushobora gutwikira imirongo myinshi ya infrared hagati. Byaba ari uburyo molekile z'amazi zinjira mu kirere cyangwa uburebure bw'umuraba budasanzwe butangwa na TM-doped na Ho fiber lasers, byose bishobora gufatwa neza.

Si ibyo gusa, module ya R-PR-2μm photodetector izwiho kwiyongera cyane, ubushobozi bwo kumva no guhindagurika neza. Ndetse n'imivuduko ya laser yo mu rwego rwa picosecond ifite intege nke cyane ishobora kumenyekana neza, bigatuma ibimenyetso byoherezwa nta gutakaza. Hagati aho, imiterere yayo y'urusaku ruto igabanya ingaruka mbi z'inyuma, iha abashakashatsi amakuru meza kandi yizewe. Module ifite imiterere nto, ishoboye gukumira ingaruka mbi z'amashanyarazi, kandi ishyigikira fibre imwe cyangwa free-space coupling input, ndetse n'umusaruro wa SMA connector, byoroshya cyane guhuza no gushyira ahagaragara. Igikwiye kuvugwa kurushaho ni uko inashyigikira guhindura ibintu hashingiwe ku byo abakiriya bakeneye. Urugero, ubuso bwubatswe muri PIN tube butuma urumuri rugaragara neza kandi rushobora guhinduka. Nubwo urumuri rudakomeye, ruracyashobora kuboneka. Module ya R-PR-2μm photodetector ituma urumuri rutagaragara mu gikorwa rugaragara, rushobora gupimwa kandi rushobora gukoreshwa.
