Ama-laser ayinkimbinkimbi we-Microcavity asuka e-odwe kuya ezifundeni ezingahlelekile

I-laser evamile iqukethe izinto ezintathu eziyisisekelo: umthombo wepompo, i-aindium yokuzuza ekhulisa imisebe evuselelwe, kanye nesakhiwo somgodi okhiqiza i-optical resonance. Lapho ubukhulu bomgodi we-laseriseduze nezinga le-micron noma le-submicron, isibe enye yezindawo ezishisayo zamanje zocwaningo emphakathini wezemfundo: ama-microcavity lasers, angafinyelela ukukhanya okubalulekile nokusebenzisana kwento ngevolumu encane. Ukuhlanganisa ama-microcavities namasistimu ayinkimbinkimbi, afana nokwethula imingcele ye-cavity engajwayelekile noma engahlelekile, noma ukwethula imidiya esebenzayo eyinkimbinkimbi noma engahlelekile ibe ngama-microcavities, kuzonyusa izinga lenkululeko yokuphuma kwe-laser. Izici ezingokomzimba ezingezona i-cloning zama-cavities aphazamisekile ziletha izindlela zokulawula ze-multidimensional zamapharamitha we-laser, futhi zinganweba amandla ayo okusebenza.

Amasistimu ahlukene wokungahleliwei-microcavity lasers
Kuleli phepha, ama-laser we-microcavity angahleliwe ahlukaniswa kusuka kubukhulu obuhlukahlukene bomgodi okokuqala ngqa. Lo mehluko awugcini nje ngokugqamisa izici ezihlukile zokukhiphayo ze-laser microcavity ezingahleliwe ngobukhulu obuhlukahlukene, kodwa futhi ucacisa izinzuzo zomehluko wosayizi we-microcavity engahleliwe emikhakheni ehlukahlukene yokulawula neyokusebenza. I-microcavity yesimo esiqinile enezinhlangothi ezintathu ivamise ukuba nevolumu yemodi encane, ngaleyo ndlela izuze ukukhanya okunamandla nokusebenzisana kwento. Ngenxa yesakhiwo sayo esivaliwe esinezinhlangothi ezintathu, inkambu yokukhanya ingenziwa endaweni kakhulu ngobukhulu obuthathu, ngokuvamile ngesici sekhwalithi ephezulu (Q-factor). Lezi zici ziyenza ifaneleke ukuzwa okunembayo okuphezulu, isitoreji se-photon, ukucutshungulwa kolwazi lwe-quantum nezinye izinkambu zobuchwepheshe obuthuthukile. Isistimu yefilimu ezacile enezinhlangothi ezimbili evulekile iyinkundla ekahle yokwakha izakhiwo zepulani ezingahlelekile. Njengendiza ye-dielectric enezinhlangothi ezimbili ephazamisekile enenzuzo edidiyelwe nokuhlakazeka, isistimu yefilimu emincane ingabamba iqhaza ngokukhuthele ekukhiqizeni i-laser engahleliwe. Umphumela we-planar waveguide wenza ukuhlangana kwe-laser nokuqoqwa kube lula. Ngokuncishiswa kobukhulu be-cavity, ukuhlanganiswa kwempendulo kanye nokuthola imidiya ku-waveguide enohlangothi olulodwa kungacindezela ukuhlakazeka kokukhanya kwe-radial ngenkathi kuthuthukisa i-axial light resonance kanye nokuhlangana. Le ndlela yokuhlanganisa ekugcineni ithuthukisa ukusebenza kahle kokukhiqizwa kwe-laser nokuhlanganisa.

Izici zokulawula zama-laser microcavity angahleliwe
Izinkomba eziningi zamalaser endabuko, njengokuhlangana, i-threshold, isiqondiso sokuphuma kanye nezici ze-polarization, izindlela eziyinhloko zokulinganisa ukusebenza kokuphuma kwama-lasers. Uma kuqhathaniswa nama-lasers avamile anezimbotshana ezilinganiselwe ezilinganiselwe, i-laser microcavity engahleliwe inikeza ukuguquguquka okwengeziwe kumthethonqubo wepharamitha, okubonakala ngezilinganiso eziningi ezihlanganisa isizinda sesikhathi, isizinda se-spectral kanye nesizinda sendawo, okugqamisa ukulawulwa kwe-multi-dimensional ye-laser microcavity engahleliwe.

Izici zohlelo lokusebenza zama-laser microcavity angahleliwe
Ukuhlangana okuphansi kwendawo, ukungahleleki kwemodi kanye nokuzwela kwemvelo kunikeza izici eziningi ezivumayo zokusetshenziswa kwama-laser we-stochastic microcavity. Ngesixazululo sokulawula imodi nokulawulwa kwesiqondiso se-laser engahleliwe, lo mthombo wokukhanya oyingqayizivele usetshenziswa kakhulu ekuthwebuleni izithombe, ekuxilongweni kwezokwelapha, ezinzwa, ekuxhumaneni kolwazi neminye imikhakha.
Njenge-laser micro-cavity ephazamisekile esikalini se-micro kanye ne-nano, i-laser ye-microcavity engahleliwe izwela kakhulu izinguquko zemvelo, futhi izici zayo ze-parametric zingaphendula izinkomba ezihlukahlukene ezibucayi eziqapha indawo yangaphandle, njengezinga lokushisa, umswakama, i-pH, ukugxila koketshezi, inkomba ye-refractive, njll., ukudala inkundla ephakeme yokubona izinhlelo zokusebenza ezizwela kakhulu. Emkhakheni wezithombe, okulungileumthombo wokukhanyakufanele ibe nokuminyana okuphezulu kwe-spectral, ukuphuma okuqinile kokuqondisa kanye nokuhlangana okuphansi kwendawo ukuze kuvinjelwe imiphumela yokuphazamiseka kwamachashaza. Abacwaningi babonise izinzuzo zama-lasers angahleliwe wokuthwebula izithombe zamahhala ku-perovskite, i-biofilm, ama-crystal scatterers kanye nabathwali bezicubu zamaseli. Ekuxilongweni kwezokwelapha, i-microcavity laser engahleliwe ingathwala ulwazi olusabalele kusuka kumsingathi webhayoloji, futhi isetshenziswe ngempumelelo ukuze kutholwe izicubu ezihlukahlukene zebhayoloji, okunikeza lula ukuxilongwa kwezokwelapha okungahlanyisi.

Ngokuzayo, ukuhlaziya okuhlelekile kwezakhiwo ze-microcavity eziphazamisekile kanye nezindlela eziyinkimbinkimbi zokukhiqiza i-laser kuzophelela kakhulu. Ngokuqhubeka okuqhubekayo kwesayensi yezinto zokwakha kanye ne-nanotechnology, kulindeleke ukuthi kwenziwe ezinye izakhiwo ze-microcavity ezingakahleleki nezisebenzayo, ezinamandla amakhulu ekukhuthazeni ucwaningo oluyisisekelo kanye nokusetshenziswa okungokoqobo.
