Microcavity complex lasers los ntawm kev txiav txim mus rau lub xeev tsis meej

Ib tug raug laser muaj peb lub hauv paus ntsiab lus: ib tug twj tso kua mis qhov chaw, ib tug nce nruab nrab uas amplifies lub stimulated hluav taws xob, thiab ib tug kab noj hniav qauv uas generates ib tug optical resonance. Thaum cov kab noj hniav loj ntawm lublasernyob ze rau qib micron lossis submicron, nws tau dhau los ua ib qho ntawm cov kev tshawb fawb tam sim no hauv zej zog kev kawm: microcavity lasers, uas tuaj yeem ua tiav lub teeb tseem ceeb thiab teeb meem cuam tshuam hauv qhov ntim me me. Kev sib xyaw cov microcavities nrog cov txheej txheem nyuaj, xws li qhia txog qhov tsis xwm yeem lossis tsis sib haum xeeb ntawm cov kab noj hniav, los yog qhia cov xov xwm ua haujlwm nyuaj lossis tsis zoo rau hauv microcavities, yuav ua rau kom muaj kev ywj pheej ntawm cov khoom siv laser. Lub cev tsis-cloning cov yam ntxwv ntawm cov kab noj hniav tsis zoo coj ntau txoj kev tswj hwm ntawm laser tsis, thiab tuaj yeem nthuav dav nws daim ntawv thov.

Sib txawv systems ntawm randommicrocavity lasers
Nyob rau hauv daim ntawv no, random microcavity lasers yog cais los ntawm txawv kab noj hniav qhov ntev thawj zaug. Qhov kev sib txawv no tsis tsuas yog qhia txog cov yam ntxwv ntawm cov khoom tsim tawm ntawm random microcavity laser hauv qhov sib txawv, tab sis kuj qhia meej qhov zoo ntawm qhov sib txawv ntawm qhov sib txawv ntawm random microcavity hauv ntau yam kev tswj hwm thiab daim ntawv thov. Peb-dimensional solid-state microcavity feem ntau muaj qhov ntim me me, yog li ua tiav lub teeb muaj zog thiab teeb meem kev sib cuam tshuam. Vim nws cov qauv kaw peb-dimensional, lub teeb pom kev zoo tuaj yeem ua haujlwm hauv peb qhov loj me, feem ntau nrog qhov zoo tshaj plaws (Q-factor). Cov yam ntxwv no ua rau nws haum rau high-precision sensing, photon cia, quantum ntaub ntawv ua thiab lwm yam advanced technology teb. Qhov qhib ob-dimensional nyias zaj duab xis system yog qhov zoo tshaj plaws platform rau kev tsim cov txheej txheem tsis sib haum xeeb. Raws li ob-dimensional disordered dielectric dav hlau nrog kev nce thiab tawg, cov txheej txheem nyias nyias tuaj yeem koom nrog hauv tiam neeg ntawm random laser. Planar waveguide effect ua rau lub laser coupling thiab sau yooj yim dua. Nrog rau cov kab noj hniav qhov ntev txo qis, kev sib koom ua ke ntawm kev tawm tswv yim thiab tau txais xov xwm rau hauv ib qho kev sib tw waveguide tuaj yeem cuam tshuam lub teeb radial tawg thaum txhim kho axial lub teeb resonance thiab coupling. Qhov kev sib koom ua ke no thaum kawg txhim kho kev ua haujlwm ntawm laser tiam thiab coupling.

Regulatory yam ntxwv ntawm random microcavity lasers
Ntau qhov ntsuas ntawm ib txwm lasers, xws li kev sib koom ua ke, qhov pib, cov kev taw qhia tso zis thiab cov yam ntxwv polarization, yog cov txheej txheem tseem ceeb los ntsuas qhov kev ua tau zoo ntawm lasers. Piv nrog cov pa lasers nrog cov kab noj hniav ruaj khov, qhov random microcavity laser muab ntau qhov kev hloov pauv hauv cov txheej txheem kev tswj hwm, uas tau cuam tshuam rau ntau qhov ntev, suav nrog lub sijhawm sau, spectral domain thiab spatial domain, tseem ceeb rau ntau qhov kev tswj hwm ntawm random microcavity laser.

Kev siv cov yam ntxwv ntawm random microcavity lasers
Tsawg spatial coherence, hom randomness thiab rhiab heev rau ib puag ncig muab ntau yam txaus nyiam rau daim ntawv thov ntawm stochastic microcavity lasers. Nrog rau kev daws teeb meem ntawm kev tswj hwm thiab kev taw qhia ntawm random laser, qhov tshwj xeeb lub teeb pom kev zoo no tau siv ntau dua hauv kev kuaj pom, kev kuaj mob, kev paub, kev sib txuas lus thiab lwm yam kev lag luam.
Raws li kev tsis sib haum xeeb micro-cavity laser ntawm micro thiab nano nplai, qhov random microcavity laser yog rhiab heev rau ib puag ncig kev hloov pauv, thiab nws cov yam ntxwv parametric tuaj yeem teb rau ntau qhov ntsuas ntsuas ntsuas qhov chaw sab nraud, xws li kub, av noo, pH, kua concentration, refractive index, thiab lwm yam., tsim kom muaj lub platform zoo tshaj plaws rau kev paub txog cov ntawv thov kev nkag siab siab. Nyob rau hauv lub teb ntawm imaging, lub zoo tagnrhoqhov kajyuav tsum muaj siab spectral ceev, muaj zog directional tso zis thiab tsawg spatial coherence kom tsis txhob cuam tshuam speckle cuam tshuam. Cov kws tshawb fawb tau pom qhov zoo ntawm random lasers rau speckle dawb imaging nyob rau hauv perovskite, biofilm, kua siv lead ua scatterers thiab cell cov ntaub so ntswg. Hauv kev kuaj mob, random microcavity laser tuaj yeem nqa cov ntaub ntawv tawg los ntawm cov tswv tsev lom neeg, thiab tau ua tiav siv los kuaj xyuas ntau cov ntaub so ntswg, uas muab kev yooj yim rau kev kuaj mob tsis muaj kev cuam tshuam.

Nyob rau hauv lub neej yav tom ntej, kev tsom xam ntawm cov txheej txheem microcavity tsis zoo thiab cov txheej txheem laser tsim yuav ua tiav ntau dua. Nrog rau kev nce qib ntawm cov ntaub ntawv tshawb fawb thiab nanotechnology, nws xav tias yuav tsim cov qauv zoo thiab ua haujlwm tsis zoo ntawm microcavity, uas muaj peev xwm loj hauv kev txhawb nqa kev tshawb fawb thiab kev siv tswv yim.
