I-Microcavity complex lasers ukusuka kwi-odolo ukuya kumazwe aphazamisekileyo

Ilaser eqhelekileyo iqulathe izinto ezintathu ezisisiseko: umthombo wempompo, indawo yokuzuza eyandisa i-radiation evuselelweyo, kunye nesakhiwo somgodi ovelisa i-optical resonance. Xa ubukhulu bomgodi welaserisondele kwinqanaba le-micron okanye i-submicron, iye yaba enye yeendawo zophando zangoku kwi-academic community: i-microcavity lasers, enokufikelela ekukhanyeni okubalulekileyo kunye nentsebenziswano yomcimbi kwivolumu encinci. Ukudibanisa i-microcavities kunye neenkqubo ezintsonkothileyo, ezinjengokwazisa imida yecango engaqhelekanga okanye engacwangciswanga, okanye ukwazisa imidiya esebenzayo entsonkothileyo okanye engasebenziyo kwi-microcavities, iya kwandisa inqanaba lenkululeko yokuphuma kwelaser. Iimpawu ezibonakalayo ezingezizo ii-cloning ze-cavities eziphazamisekileyo zizisa iindlela zokulawula ezininzi ze-laser parameters, kwaye inokwandisa amandla ayo okusebenza.

Iinkqubo ezahlukeneyo ze-randomiilaser microcavity
Kweli phepha, ii-laser ze-microcavity ezingahleliwe zihlelwa ukusuka kwimilinganiselo eyahlukeneyo yecavity okokuqala. Olu lwahlulo alubonakalisi kuphela iimpawu ezikhethekileyo zemveliso ye-laser ye-random microcavity kwimilinganiselo eyahlukeneyo, kodwa iphinda icacise inzuzo yokwahlukana kobukhulu be-random microcavity kwiinkalo ezahlukeneyo zokulawula kunye nesicelo. I-microcavity ye-slid-dimensional-state-state microcavity idla ngokuba nomthamo omncinci wemowudi, ngaloo ndlela ifezekisa ukukhanya okunamandla kunye nentsebenziswano yomcimbi. Ngenxa yesakhiwo sayo esivaliweyo esine-dimensional emithathu, intsimi yokukhanya inokuthi ibekwe kwindawo ephezulu kwiindawo ezintathu, ngokuphindaphindiweyo kunye nomgangatho ophezulu (Q-factor). Ezi mpawu zenza ukuba zilungele ukuchaneka okuphezulu, ukugcinwa kwefoton, ukusetyenzwa kolwazi lwe-quantum kunye nezinye iinkalo zobuchwepheshe obuphambili. Inkqubo yefilim evulekileyo enamacala amabini liqonga elifanelekileyo lokwakha izakhiwo ezicwangcisiweyo zeplani. Njengoko i-dielectric dielectric plane ene-dimensional disorder inenzuzo edibeneyo kunye nokusabalalisa, inkqubo yefilimu encinci inokuthatha inxaxheba ngokusebenzayo ekuveliseni i-laser random. Impembelelo ye-waveguide ecwangcisiweyo yenza ukudibanisa kwe-laser kunye nokuqokelela kube lula. Ngomda we-cavity uncitshiswe ngakumbi, ukudityaniswa kwengxelo kunye nokufumana imithombo yeendaba kwi-wave-dimensional waveguide kunokucinezela ukusasazwa kokukhanya kweradial ngelixa uphucula i-axial light resonance kunye nokudibanisa. Le ndlela yokudibanisa ekugqibeleni iphucula ukusebenza kakuhle kokuveliswa kwe-laser kunye nokudibanisa.

Iimpawu zokulawula i-laser microcavity engahleliwe
Izalathisi ezininzi zeelaser zemveli, ezinje ngokuhambelana, umqobo, umkhombandlela wokuphuma kunye neempawu zepolarization, ziikhrayitheriya eziphambili zokulinganisa ukusebenza kwe-lasers. Xa kuthelekiswa nama-lasers aqhelekileyo anemiqolo eqingqiweyo ye-symmetric cavities, i-random microcavity laser inikezela ukuguquguquka ngakumbi kulawulo lweparameter, ebonakaliswa kwimilinganiselo emininzi kuquka i-domain yexesha, i-spectral domain kunye ne-spatial domain, egxininisa ukulawulwa kwe-multi-dimensional ye-random microcavity laser.

Iimpawu zokusetyenziswa kwe-laser microcavity random
Ukuhambelana kwendawo ephantsi, imowudi yokungakhethi kunye novakalelo lokusingqongileyo lubonelela ngezinto ezininzi ezifanelekileyo zokusetyenziswa kwe-laser ye-stochastic microcavity. Ngesisombululo solawulo lwemowudi kunye nokulawulwa kolwalathiso lwe-laser random, lo mthombo wokukhanya oyingqayizivele usetyenziswa ngakumbi kwi-imaging, ukuxilongwa kwezonyango, ukuva, ukunxibelelana ngolwazi kunye nezinye iinkalo.
Njenge-laser ye-micro-cavity ephazamisekileyo kwisikali se-micro kunye ne-nano, i-laser ye-microcavity engahleliwe ivakalelwa kakhulu kwiinguqu zendalo, kwaye iimpawu zayo ze-parametric zinokuphendula kwizibonakaliso ezahlukeneyo zokubeka iliso kwimeko yangaphandle, efana nobushushu, ukufuma, i-pH, i-concentration yolwelo, isalathiso se-refractive, njl., ukudala iqonga eliphezulu lokuqonda izicelo zovakalelo oluphezulu. Kwintsimi yomfanekiso, eyona nto ifanelekileyoumthombo wokukhanyakufuneka ibenoxinaniso oluphezulu lokubonwayo, isiphumo esinamandla sakwalathisi kunye nokuhambelana kwesithuba esisezantsi ukunqanda uphazamiseko lweziphumo zamachaphaza. Abaphandi babonise iingenelo zeelaser ezingahleliweyo zokucinga simahla kwi-perovskite, i-biofilm, i-crystal scatterers kunye nabathwali beeseli zeseli. Kuxilongo lwezonyango, i-random microcavity laser inokuthwala ulwazi olusasazekileyo oluvela kwi-biological host, kwaye isetyenziswe ngempumelelo ukufumanisa izicubu zebhayoloji ezahlukeneyo, ezibonelela ngokulula kuxilongo lwezonyango olungaphazamisiyo.

Kwixesha elizayo, uhlalutyo olucwangcisiweyo lwezakhiwo ze-microcavity eziphazamisekileyo kunye neendlela ezinzima zokuvelisa i-laser ziya kugqitywa ngakumbi. Ngenkqubela phambili eqhubekayo yesayensi yezixhobo kunye ne-nanotechnology, kulindeleke ukuba kuphuculwe ngakumbi kwaye kusebenze izakhiwo ze-microcavity ezingasebenziyo ziya kwenziwa, ezinokubakho okukhulu ekukhuthazeni uphando olusisiseko kunye nokusetyenziswa okusebenzayo.
