Imirasire ya microcavity complex iva mu bihugu byategetswe kugera mu byangiritse

Laser isanzwe igizwe n'ibintu bitatu by'ibanze: isoko ya pompe, uburyo bwo kongera umusaruro w'imirasire itera imbaraga, n'imiterere y'aho hantu hakora urumuri. Iyo ingano y'aho hantu hamezelaseriri hafi y’urwego rwa micron cyangwa submicron, yabaye imwe mu nyubako z’ubushakashatsi zigezweho mu muryango w’abahanga: lasers za microcavity, zishobora kugera ku imikoranire ikomeye y’urumuri n’ibintu mu rugero ruto. Guhuza microcavities na sisitemu zigoye, nko gushyira imipaka idasanzwe cyangwa idasobanutse neza, cyangwa gushyira ibyuma bito cyangwa bidasobanutse neza mu byuma bito, byongera ubwisanzure bw’ibicuruzwa bya laser. Imiterere y’ibice bidasobanutse neza by’ibice bidasobanutse neza bitanga uburyo bwinshi bwo kugenzura ibipimo bya laser, kandi bishobora kwagura ubushobozi bwayo bwo kuyikoresha.

Sisitemu zitandukanye z'uburyo butunguranyelasers ntoya
Muri iyi nyandiko, laser za microcavity zisanzwe zishyirwa mu byiciro bitandukanye by’ubuso ku nshuro ya mbere. Iri tandukaniro ntirigaragaza gusa imiterere yihariye y’umusaruro wa laser ya microcavity isanzwe mu bipimo bitandukanye, ahubwo rinasobanura ibyiza by’itandukaniro ry’ingano ya microcavity isanzwe mu nzego zitandukanye zigenga n’izikoreshwa. Microcavity ifite imiterere itatu isanzwe ifite ingano ntoya y’uburyo, bityo ikaba ifite imikoranire ikomeye y’urumuri n’ibintu. Bitewe n’imiterere yayo ya 3-dimensional ifunze, urumuri rushobora gushyirwa ahantu henshi mu bipimo bitatu, akenshi rufite factor nziza (Q-factor). Ibi biranga bituma ikwiriye kumenya neza, kubika photon, gutunganya amakuru ya quantum n’izindi nzego zigezweho z’ikoranabuhanga. Sisitemu ya filime nto ifunguye ni urubuga rwiza rwo kubaka inyubako za planar zitameze neza. Nk’indege ya dielectric ifite imiterere ibiri ifite imiterere ibiri ifite ubwiyongere buhuriweho kandi ikwirakwira, sisitemu ya filime nto ishobora kugira uruhare runini mu gukora laser ya random. Ingaruka za planar waveguide zituma guhuza no gukusanya laser byoroha. Iyo ingano y'aho umwobo uherereye igabanutse cyane, guhuza ibitekerezo n'uburyo bwo kubona amakuru mu buryo bumwe bishobora gukumira gutatana k'urumuri rw'imirasire mu gihe byongera imbaraga zo guhuza urumuri rw'imirongo n'imirongo. Ubu buryo bwo guhuza ibintu bunoza imikorere y'ikoranabuhanga rya laser no guhuza.

Imiterere y'amabwiriza ya lasers za microcavity zidasanzwe
Ibipimo byinshi bya laser gakondo, nko guhuza, urwego rw'umusaruro, icyerekezo cy'umusaruro n'imiterere ya polarization, ni byo bipimo by'ingenzi byo gupima imikorere y'umusaruro wa laser. Ugereranyije na laser zisanzwe zifite imiyoboro idahinduka, laser ya microcavity idasanzwe itanga ubworoherane mu kugenzura ibipimo, ibi bikaba bigaragarira mu bipimo byinshi birimo igihe, urwego rwa spectral n'urwego rw'ahantu, bigaragaza ubushobozi bwo kugenzura ibintu byinshi bwa laser ya microcavity idasanzwe.

Ibiranga ikoreshwa rya lasers za microcavity zidasanzwe
Ubwumvikane buke mu mwanya, uburyo bworoshye bwo gukora ibintu no gusobanukirwa ibidukikije bitanga ibintu byinshi byiza byo gukoresha laser za microcavity. Hamwe n'uburyo bwo kugenzura uburyo bwo gukora ibintu no kugenzura icyerekezo cya laser ya random, iyi soko ryihariye ry'urumuri rikoreshwa cyane mu gufata amashusho, gusuzuma indwara, kumenya amakuru, itumanaho n'ibindi.
Nk'icyuma gikoresha utuntu duto duto (micro-cavity laser) giteye ikibazo ku gipimo cya micro na nano, icyo cyuma gikoresha utuntu duto duto (random microcavity laser) gikunze kwibasirwa cyane n'impinduka mu bidukikije, kandi imiterere yacyo ishobora gusubiza ibimenyetso bitandukanye bigenzura ibidukikije byo hanze, nk'ubushyuhe, ubushuhe, pH, ubucucike bw'amazi, igipimo cyo kurekura, n'ibindi, bigatuma habaho urubuga rwiza rwo gushyira mu bikorwa porogaramu zo kumenya ubukana bw'ibintu. Mu rwego rwo gufata amashusho, ni byiza cyaneisoko y'urumuriIgomba kugira ubucucike bwinshi bwa spectral, ubushobozi bukomeye bwo gutanga icyerekezo ndetse n'ubushobozi buke bwo guhuza imiterere y'ahantu kugira ngo hirindwe ingaruka za speckle. Abashakashatsi bagaragaje ibyiza bya laser random mu gufata amashusho adafite speckle muri perovskite, biofilm, liquid crystal scatterers na cell tissue carriers. Mu gusuzuma indwara, laser random microcavity ishobora gutwara amakuru atatanye aturutse ku muntu utuye mu mubiri, kandi yakoreshejwe neza mu gutahura ingirabuzima fatizo zitandukanye, ibyo bikaba byorohereza gusuzuma indwara mu buryo butari ubwandu.

Mu gihe kizaza, isesengura ryimbitse ry’imiterere y’uturemangingo tw’uturemangingo duto duto hamwe n’uburyo bugoye bwo gukora imirasire ya laser rizarushaho kuba ryuzuye. Bitewe n’iterambere rihoraho ry’ubumenyi bw’ibikoresho na nanotechnology, byitezwe ko hazakorwa inyubako nziza kandi zikora neza z’uturemangingo duto duto duto, zifite ubushobozi bukomeye mu guteza imbere ubushakashatsi bw’ibanze n’ikoreshwa ryabyo mu buryo bufatika.
