Laysarka isku dhafan ee microcavity laga bilaabo la dalbaday ilaa dawlado khalkhalsan

Laysarka caadiga ah wuxuu ka kooban yahay saddex walxood oo aasaasi ah: isha bamka, dhexdhexaadka faa'iido ee kor u qaada shucaaca la kiciyey, iyo qaab dhismeedka godka kaas oo dhaliya dhawaaq-arag. Marka xajmiga godka eeleysarkawaxay ku dhowdahay heerka micron ama submicron, waxay noqotay mid ka mid ah goobaha cilmi-baarista ee hadda jira ee bulshada tacliinta: lasers microcavity, kaas oo ku gaari kara isdhexgalka iftiinka iyo walxaha mugga yar. Isku-dubbaridka unugyada yaryar ee nidaamyada adag, sida soo bandhigida xudduudaha daloolka aan caadiga ahayn ama khalkhalka leh, ama soo bandhigida warbaahinta shaqada ee kakan ama khalkhalka leh ee microcavities, waxay kordhin doontaa heerka xorriyadda wax soo saarka laysarka. Astaamaha jireed ee aan-xinjirowga ahayn ee godadka khalkhalka leh waxay keenaan habab xakameyn badan oo cabbirka laysarka, waxayna ballaarin kartaa awooddeeda codsi.

Nidaamyo kala duwan oo random ahleysarka microcavity
Warqadan, laysarka yar yar ee random ayaa markii ugu horeysay laga soocay cabbiro kala duwan oo dalool ah. Kala soocidaani ma aha oo kaliya inay muujiso sifooyinka wax soo saarka gaarka ah ee leysarka microcavity random ee cabbirro kala duwan, laakiin sidoo kale waxay caddeysaa faa'iidooyinka kala duwanaanshaha cabbirka ee microcavity random ee sharciyeynta iyo codsiyada kala duwan. Microcavity-ka adag ee saddex-geesoodka ah ayaa badanaa leh mugga qaab yar, sidaas darteed lagu gaaro iftiin xooggan iyo isdhexgalka arrinta. Iyada oo ay ugu wacan tahay qaab-dhismeedkeeda saddex-geesoodka ah ee xiran, goobta iftiinka ayaa si heer sare ah loogu dhejin karaa saddex cabbir, oo badanaa leh arrin tayo sare leh (Q-factor). Sifooyinkan ayaa ka dhigaya mid ku habboon dareenka saxda ah ee saxda ah, kaydinta photon, habaynta macluumaadka tirada iyo qaybaha kale ee tignoolajiyada horumarsan. Nidaamka filimka khafiifka ah ee laba-geesoodka ah ee furan ayaa ah meel ku habboon oo lagu dhisayo qaab-dhismeedyada qorshaysan ee khalkhalsan. Sida diyaarad dielectric laba-cabbir ah oo khalkhalsan oo leh faa'iido isku dhafan iyo kala firidhsan, nidaamka filimka khafiifka ah wuxuu si firfircoon uga qayb qaadan karaa jiilka laser random. Saamaynta waveguide planar ayaa ka dhigaysa isku xidhka laysarka iyo ururinta mid sahlan. Iyada oo cabbirka daloolku uu sii yaraanayo, isku-dhafka jawaab-celinta iyo helitaanka warbaahinta ee jihada hal-beeglaha ah waxay xakameyn kartaa firdhinta iftiinka shucaaca iyada oo kor u qaadeysa dhawaaqa iftiinka axial iyo isku-xirnaanta. Habkan isdhexgalka ayaa ugu dambeyntii hagaajinaya waxtarka jiilka laysarka iyo isku xirka.

Astaamaha sharciyeynta ee leysarka microcavity random
Tilmaamayaal badan oo ka mid ah laser-dhaqameedka, sida isku xirnaanta, marinka, jihada wax soo saarka iyo sifooyinka polarization, ayaa ah shuruudaha ugu muhiimsan ee lagu cabbirayo waxqabadka wax soo saarka laysarka. Marka la barbar dhigo laysarka caadiga ah ee leh godadka summadaha go'an, leysarka microcavity random wuxuu bixiyaa dabacsanaan dheeraad ah oo ku saabsan jaangooyooyinka cabbirka, kaas oo ka muuqda cabbirro badan oo ay ku jiraan domain-ka wakhtiga, domain-ka muuqaalka iyo goobta goobta, taasoo muujinaysa xakamaynta cabbirrada badan ee leysarka microcavity random.

Tilmaamaha codsiga ee leysarka microcavity random
Isku xirnaanta boosaska hooseeya, kala-soocida qaabka iyo dareenka deegaanka ayaa bixiya arrimo badan oo wanaagsan oo loogu talagalay isticmaalka lasers-ka yar ee stochastic. Iyada oo la adeegsanayo xallinta xakamaynta qaabka iyo xakamaynta jihada ee laser random, ishan iftiinka gaarka ah ayaa si sii kordheysa loogu isticmaalo sawir-qaadista, ogaanshaha caafimaadka, dareenka, isgaarsiinta macluumaadka iyo qaybaha kale.
Sida laser godka-yar-yar ee khalkhalsan ee cabbirka micro iyo nano, laser microcavity random wuxuu aad ugu nugul yahay isbeddelada deegaanka, iyo sifooyinkiisa parametric waxay ka jawaabi karaan tilmaamayaasha xasaasiga ah ee kala duwan ee kormeeraya deegaanka dibadda, sida heerkulka, qoyaanka, pH, feejignaanta dareeraha, index refractive, iwm., abuurista madal sare si loo xaqiijiyo codsiyada dareenka sare. Dhinaca sawirka, ku habboonil iftiin lehwaa in uu lahaadaa cufnaan muuqaal sare leh, soo saarid jihada xooggan iyo isku xirnaanta bannaanka oo hooseeysa si looga hortago saameynta xadhkaha goosashada. Cilmi-baadhayaashu waxay soo bandhigeen faa'iidooyinka laysarka random ee sawir-qaadista bilaashka ah ee perovskite, biofilm, dareerayaasha crystals-ka iyo sidayaasha unugyada unugyada. Baaritaanka caafimaadka, laser microcavity random wuxuu ka qaadi karaa macluumaadka kala firirsan ee martida noolaha, waxaana si guul leh loogu dabaqay si loo ogaado unugyo bayooloji oo kala duwan, taas oo bixisa ku habboonaanta ogaanshaha caafimaad ee aan fiicneyn.

Mustaqbalka, falanqaynta habaysan ee qaab-dhismeedka microcavity khalkhalka leh iyo hababka jiilka laysarka ee adag ayaa noqon doona mid dhamaystiran. Horumarka joogtada ah ee sayniska agabka iyo nanotechnology, waxa la filayaa in la soo saari doono qaab-dhismeedyo cilladaysan oo qurux badan oo shaqaynaya, kaas oo awood weyn u leh horumarinta cilmi-baarista aasaasiga ah iyo codsiyada la taaban karo.
