Iilaser zeMicrocavity complex ezivela kumazwe acwangcisiweyo ukuya kwangaphazamiyo

I-laser eqhelekileyo inezinto ezintathu ezisisiseko: umthombo wepompo, i-gain medium eyandisa imitha evuselelweyo, kunye nesakhiwo se-cavity esivelisa i-optical resonance. Xa ubungakanani be-cavity ye-ilezaikufutshane nenqanaba le-micron okanye i-submicron, ibe yenye yezona ndawo ziphambili zophando kuluntu lwezemfundo: ii-laser ze-microcavity, ezinokufezekisa ukusebenzisana okubalulekileyo kokukhanya kunye nezinto ngomthamo omncinci. Ukudibanisa ii-microcavities neenkqubo ezintsonkothileyo, njengokungenisa imida ye-cavity engacwangciswanga okanye engacwangciswanga, okanye ukungenisa i-complex okanye i-disordered working media kwii-microcavities, kuya kwandisa inqanaba lenkululeko yokukhupha i-laser. Iimpawu ze-physical non-cloning ze-disordered cavities zizisa iindlela zokulawula ezininzi zeeparameter ze-laser, kwaye zinokukhulisa amandla ayo okusetyenziswa.

Iinkqubo ezahlukeneyo ze-randomiileza ze-microcavity
Kule phepha, ii-laser ze-microcavity ezingacwangciswanga zahlulwe kwiimilinganiselo ezahlukeneyo ze-cavity okokuqala. Olu mahluko alubonisi nje kuphela iimpawu ezizodwa zemveliso ye-laser ye-microcavity engacwangciswanga kwiimilinganiselo ezahlukeneyo, kodwa lukwacacisa neengenelo zomahluko wobungakanani be-microcavity engacwangciswanga kwiinkalo ezahlukeneyo zolawulo kunye nezicelo. I-microcavity ye-solid-state enemilinganiselo emithathu idla ngokuba nomthamo omncinci wemodi, ngaloo ndlela ifezekisa ukusebenzisana okunamandla kokukhanya kunye nezinto. Ngenxa yesakhiwo sayo esivaliweyo esinemilinganiselo emithathu, intsimi yokukhanya inokubekwa kwindawo ephezulu kwiimilinganiselo ezintathu, rhoqo nge-factor yomgangatho ophezulu (Q-factor). Ezi mpawu ziyenza ifaneleke kwi-high-precision sensing, i-photon storage, i-quantum information processing kunye nezinye iindawo zobuchwepheshe obuphambili. Inkqubo yefilimu evulekileyo enemilinganiselo emibini ecacileyo liqonga elifanelekileyo lokwakha izakhiwo ze-planar ezingacwangciswanga. Njengeplane ye-dielectric engacwangciswanga enemilinganiselo emibini ene-gain and scattering edibeneyo, inkqubo yefilimu encinci inokuthatha inxaxheba ngokukhutheleyo ekudalweni kwe-laser engacwangciswanga. Isiphumo se-planar waveguide senza ukuba ukudibana kwe-laser kunye nokuqokelelwa kube lula. Njengoko ubukhulu bomngxuma buncitshiswa ngakumbi, ukuhlanganiswa kwempendulo kunye ne-gain media kwi-waveguide enomlinganiselo omnye kunokuthintela ukusasazeka kokukhanya kwe-radial ngelixa kuphucula i-axial light resonance kunye ne-coupling. Le ndlela yokudibanisa ekugqibeleni iphucula ukusebenza kakuhle kokuveliswa kunye ne-coupling ye-laser.

Iimpawu zolawulo ze-laser ze-microcavity ezingacwangciswanga
Izalathisi ezininzi zeelaser zemveli, ezinje ngokuhambelana, umda, indlela yokuphuma kunye neempawu ze-polarization, zezona zinto zibalulekileyo zokulinganisa ukusebenza kwemveliso yeelaser. Xa kuthelekiswa neelaser zemveli ezinee-fixed symmetric cavities, i-random microcavity laser inika ukuguquguquka okungakumbi kulawulo lweeparameter, olubonakala kwiimilinganiselo ezininzi kubandakanya i-time domain, i-spectral domain kunye ne-spatial domain, nto leyo egxininisa ukulawulwa kwe-multi-dimensional kwe-random microcavity laser.

Iimpawu zesicelo se-random microcavity lasers
Ukuhambelana okuphantsi kwendawo, ukungacwangciswanga kwendlela kunye novakalelo kwindawo engqongileyo kubonelela ngezinto ezininzi ezilungileyo zokusetyenziswa kwee-laser ze-stochastic microcavity. Ngesisombululo solawulo lwendlela kunye nolawulo lwendlela ye-laser engacwangciswanga, lo mthombo wokukhanya ukhethekileyo usetyenziswa ngakumbi kwimifanekiso, ukuxilongwa kwezonyango, ukuva, unxibelelwano lolwazi kunye nezinye iinkalo.
Njenge-laser ye-micro-cavity engacwangciswanga kwisikali se-micro kunye ne-nano, i-random microcavity laser inovelwano kakhulu kutshintsho lwendalo, kwaye iimpawu zayo ze-parametric zinokuphendula kwizalathisi ezahlukeneyo ezinovelwano ezijonga imeko-bume yangaphandle, ezinje ngobushushu, ukufuma, i-pH, uxinano lolwelo, i-refractive index, njl.njl., nto leyo edala iqonga eliphezulu lokufezekisa izicelo zokuvavanya uvakalelo oluphezulu. Kwicandelo lomfanekiso, eyona ifanelekileyoumthombo wokukhanyakufuneka ibe noxinano oluphezulu lwe-spectral, imveliso enamandla yesikhokelo kunye nokuhambelana okuphantsi kwendawo ukuthintela ukuphazamiseka kweziphumo ze-speckle. Abaphandi babonise iingenelo ze-random lasers kwi-speckle free imaging kwi-perovskite, i-biofilm, i-liquid crystal scatterers kunye nabathwali bezicubu zeseli. Ekuxilongweni kwezonyango, i-random microcavity laser inokuthwala ulwazi olusasazekileyo oluvela kumnini webhayoloji, kwaye isetyenziswe ngempumelelo ukufumanisa izicubu ezahlukeneyo zebhayoloji, nto leyo ebonelela ngokulula ukuxilongwa kwezonyango okungangenisi.

Kwixesha elizayo, uhlalutyo olucwangcisiweyo lwezakhiwo ze-microcavity eziphazamisekileyo kunye neendlela ezintsonkothileyo zokwenza i-laser ziya kuphelela ngakumbi. Ngokuqhubeka kwenzululwazi yezinto kunye ne-nanotechnology, kulindeleke ukuba kwenziwe izakhiwo ze-microcavity eziphazamisekileyo nezisebenzayo, ezinokuba namandla amakhulu okukhuthaza uphando olusisiseko kunye nokusetyenziswa okusebenzayo.
