Microcavity complex lasers kuva yategetswe kuri leta zidahwitse

Lazeri isanzwe igizwe nibintu bitatu byibanze: isoko ya pompe, uburyo bwo kunguka bwongera imirasire ikanguka, hamwe nuburinganire bwabyara optique ya optique. Iyo ingano yubunini bwalaserni hafi ya micron cyangwa submicron urwego, rwabaye kimwe mubibanza byubushakashatsi bigezweho mumuryango w’amasomo: laseri ya microcavity, ishobora kugera ku mucyo n’ibintu bifatika mu mubare muto. Guhuza microcavities hamwe na sisitemu igoye, nko kwinjiza imipaka idasanzwe cyangwa idahwitse, cyangwa kwinjiza ibitangazamakuru bikora bigoye cyangwa bidahwitse muri microcavities, bizamura urwego rwubwisanzure bwo gusohora laser. Ibiranga umubiri bidafite cloni biranga imyanda idahwitse bizana uburyo bwinshi bwo kugenzura ibipimo bya laser, kandi birashobora kwagura ubushobozi bwabyo.

Sisitemu zitandukanye zidasanzwemicrocavity laseri
Muriyi mpapuro, lazeri ya microcavity idasanzwe yashyizwe mubyiciro bitandukanye bya cavity kunshuro yambere. Iri tandukanyirizo ntirigaragaza gusa ibiranga umusaruro udasanzwe wa lazeri ya microcavity idasanzwe mu bipimo bitandukanye, ariko inasobanura ibyiza byubunini butandukanye bwa microcavity idasanzwe muburyo butandukanye bwo kugenzura no gushyira mubikorwa. Ibice bitatu-bigizwe na microcavity mubisanzwe bifite ingano ntoya, bityo bikagera kumucyo ukomeye no guhuza ibintu. Bitewe nuburyo butatu bufunze imiterere, umurima wumucyo urashobora kuba murwego rwo hejuru mubice bitatu, akenshi hamwe nibintu byiza (Q-factor). Ibiranga bituma bikwiranye no kumva neza, kubika fotone, gutunganya amakuru ya kwantani nizindi nzego zikoranabuhanga zateye imbere. Gufungura ibice bibiri-binini bya firime sisitemu nuburyo bwiza bwo kubaka imiterere idahwitse. Nindege ya dielectric indege ifite ibice bibiri ifite inyungu hamwe no gutatanya, sisitemu ya firime yoroheje irashobora kugira uruhare mukubyara lazeri idasanzwe. Ingaruka ya planar waveguide ituma laser ihuza hamwe no gukusanya byoroshye. Hamwe nimiterere ya cavity irushijeho kugabanuka, guhuza ibitekerezo no kunguka itangazamakuru mumurongo umwe wumurongo wumurongo urashobora guhagarika urumuri rwumucyo ukwirakwiza mugihe byongera urumuri rwumucyo no guhuza. Ubu buryo bwo kwishyira hamwe amaherezo butezimbere imikorere ya laser no guhuza.

Ibiranga amabwiriza ya microcavity idasanzwe
Ibipimo byinshi byerekana lazeri gakondo, nka coherence, imbibi, ibisohoka icyerekezo hamwe nibiranga polarisiyonike, nibyo bipimo ngenderwaho byo gupima umusaruro wa laseri. Ugereranije na lazeri zisanzwe hamwe na cavite zifatika zifatika, lazeri ya microcavity idasanzwe itanga uburyo bworoshye mugutondekanya ibipimo, ibyo bikaba bigaragarira mubice byinshi birimo igihe cyagenwe, indangagihe ya domaine hamwe na domaine y'ahantu, bikagaragaza uburyo bwinshi bwo kugenzura imiterere ya microcavity laser.

Gukoresha ibiranga microcavity idasanzwe
Guhuza umwanya muto, uburyo bwo guhitamo no kwiyumvisha ibidukikije bitanga ibintu byinshi byiza byo gukoresha microcavity lazeri. Hamwe nigisubizo cyo kugenzura uburyo no kugenzura icyerekezo cya laser, iyi soko idasanzwe yumucyo ikoreshwa cyane mugushushanya, gusuzuma ubuvuzi, kumva, itumanaho ryamakuru nizindi nzego.
Nka lazeri ya micro-cavity idahwitse ku gipimo cya micro na nano, lazeri ya microcavity idasanzwe yunvikana cyane n’imihindagurikire y’ibidukikije, kandi ibimenyetso byayo birashobora gusubiza ibimenyetso bitandukanye byerekana ibidukikije, nkubushyuhe, ubushuhe, pH, kwibanda ku mazi, indangantego, nibindi, gushiraho urubuga rwo hejuru rwo kumenya-sensibilité sensing progaramu. Mu rwego rwo gufata amashusho, nibyizaisoko yumucyoIgomba kugira ubucucike bukabije, ibyerekezo bikomeye bisohoka hamwe no guhuza umwanya muto kugirango wirinde ingaruka ziterwa nudusimba. Abashakashatsi berekanye ibyiza bya laseri zidasanzwe zo gushushanya amashusho yubusa muri perovskite, biofilm, ikwirakwiza amazi ya kirisiti hamwe nabatwara ingirabuzimafatizo. Mugupima kwa muganga, lazeri ya microcavity idasanzwe irashobora gutwara amakuru atatanye kubakira ibinyabuzima, kandi yakoreshejwe neza kugirango hamenyekane ingirabuzimafatizo zitandukanye, zitanga uburyo bworoshye bwo gusuzuma indwara zidatera.

Mu bihe biri imbere, isesengura risesuye ryimiterere ya microcavity itunganijwe hamwe nuburyo bukomeye bwo kubyara laser bizarushaho kuba byuzuye. Hamwe niterambere rikomeje ryibikoresho siyanse na nanotehnologiya, biteganijwe ko hazakorwa izindi nzego nziza kandi zidahwitse za microcavity, zifite imbaraga nyinshi mugutezimbere ubushakashatsi bwibanze nibikorwa bifatika.
