Cov lasers microcavity complex los ntawm kev txiav txim mus rau cov xeev tsis sib haum xeeb

Ib lub laser feem ntau muaj peb lub ntsiab lus tseem ceeb: lub twj tso kua mis, qhov nruab nrab uas ua kom lub zog hluav taws xob loj dua, thiab cov qauv kab uas tsim kom muaj kev cuam tshuam ntawm lub teeb. Thaum qhov loj ntawm qhov kab ntawmlasernyob ze rau qib micron lossis submicron, nws tau dhau los ua ib qho ntawm cov chaw tshawb fawb tam sim no hauv zej zog kev kawm: microcavity lasers, uas tuaj yeem ua tiav lub teeb thiab cov khoom sib cuam tshuam tseem ceeb hauv qhov me me. Kev sib xyaw ua ke microcavities nrog cov kab ke nyuaj, xws li kev qhia txog cov ciam teb tsis sib xws lossis tsis sib haum xeeb, lossis kev qhia txog cov xov xwm ua haujlwm nyuaj lossis tsis sib haum xeeb rau hauv microcavities, yuav ua rau muaj kev ywj pheej ntawm cov zis laser. Cov yam ntxwv tsis yog cloning ntawm cov kab ke tsis sib haum xeeb coj ntau txoj hauv kev tswj hwm ntawm cov txheej txheem laser, thiab tuaj yeem nthuav nws cov peev xwm siv.

Cov txheej txheem sib txawv ntawm randomcov lasers me me
Hauv daim ntawv no, cov lasers microcavity random tau raug faib ua pawg los ntawm ntau qhov sib txawv ntawm qhov sib txawv rau thawj zaug. Qhov kev sib txawv no tsis yog tsuas yog qhia txog cov yam ntxwv tshwj xeeb ntawm cov laser microcavity random hauv ntau qhov sib txawv, tab sis kuj qhia meej txog qhov zoo ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov microcavity random hauv ntau qhov kev cai lij choj thiab daim ntawv thov. Peb-seem solid-state microcavity feem ntau muaj qhov ntim me dua, yog li ua tiav lub teeb thiab cov khoom sib cuam tshuam muaj zog dua. Vim nws cov qauv kaw peb-seem, lub teeb teb tuaj yeem nyob hauv peb qhov sib txawv, feem ntau nrog qhov zoo (Q-factor). Cov yam ntxwv no ua rau nws tsim nyog rau kev ntsuas siab, kev khaws cia photon, kev ua cov ntaub ntawv quantum thiab lwm yam thev naus laus zis siab heev. Lub kaw lus nyias nyias ob-seem qhib yog lub platform zoo tagnrho rau kev tsim cov qauv planar tsis sib haum xeeb. Raws li ob-seem disordered dielectric dav hlau nrog kev sib xyaw ua ke thiab kev tawg, lub kaw lus nyias nyias tuaj yeem koom nrog hauv tiam ntawm laser random. Cov nyhuv planar waveguide ua rau kev sib txuas laser thiab kev sau yooj yim dua. Thaum qhov loj ntawm lub qhov (cavity) raug txo qis ntxiv, kev koom ua ke ntawm cov lus teb rov qab thiab cov xov xwm nce mus rau hauv ib-seem waveguide tuaj yeem tiv thaiv kev tawg ntawm lub teeb radial thaum txhim kho lub teeb axial resonance thiab kev sib txuas. Txoj hauv kev sib koom ua ke no thaum kawg txhim kho qhov ua tau zoo ntawm kev tsim laser thiab kev sib txuas.

Cov yam ntxwv tswj hwm ntawm cov lasers microcavity random
Muaj ntau yam qhia txog cov lasers ib txwm muaj, xws li kev sib koom ua ke, qhov ntsuas, kev taw qhia tawm thiab cov yam ntxwv polarization, yog cov qauv tseem ceeb los ntsuas qhov ua tau zoo ntawm cov lasers. Piv nrog cov lasers ib txwm muaj nrog cov qhov sib npaug ruaj khov, cov laser microcavity random muab kev ywj pheej ntau dua hauv kev tswj hwm parameter, uas tau cuam tshuam hauv ntau qhov ntev suav nrog lub sijhawm sau, spectral sau thiab spatial sau, qhia txog ntau qhov kev tswj hwm ntawm random microcavity laser.

Cov yam ntxwv ntawm daim ntawv thov ntawm random microcavity lasers
Qhov tsis sib xws ntawm qhov chaw, hom randomness thiab kev nkag siab rau ib puag ncig muab ntau yam zoo rau kev siv stochastic microcavity lasers. Nrog rau kev daws teeb meem ntawm kev tswj hom thiab kev tswj kev taw qhia ntawm random laser, qhov chaw teeb pom kev zoo tshwj xeeb no tau siv ntau dua hauv kev thaij duab, kev kuaj mob, kev ntsuas, kev sib txuas lus thiab lwm yam teb.
Raws li lub laser micro-cavity tsis sib haum xeeb ntawm qhov ntsuas me me thiab nano, lub laser microcavity random yog qhov rhiab heev rau kev hloov pauv ib puag ncig, thiab nws cov yam ntxwv parametric tuaj yeem teb rau ntau yam ntsuas rhiab heev saib xyuas ib puag ncig sab nraud, xws li kub, av noo, pH, kua concentration, refractive index, thiab lwm yam, tsim kom muaj lub platform zoo dua rau kev paub txog kev siv siab-sensitive sensing. Hauv thaj chaw ntawm kev thaij duab, qhov zoo tagnrholub teeb ciyuav tsum muaj qhov ceev spectral siab, muaj zog tso zis thiab qis spatial coherence kom tiv thaiv kev cuam tshuam speckle effects. Cov kws tshawb fawb tau ua pov thawj qhov zoo ntawm random lasers rau speckle free imaging hauv perovskite, biofilm, kua crystal scatterers thiab cell tissue carriers. Hauv kev kuaj mob, random microcavity laser tuaj yeem nqa cov ntaub ntawv tawg los ntawm tus tswv tsev biological, thiab tau ua tiav siv los ntes ntau yam biological tissue, uas muab kev yooj yim rau kev kuaj mob tsis-invasive.

Yav tom ntej, kev tshuaj xyuas cov qauv microcavity tsis sib haum xeeb thiab cov txheej txheem tsim laser nyuaj yuav ua tiav ntau dua. Nrog rau kev nce qib tas mus li ntawm cov ntaub ntawv tshawb fawb thiab nanotechnology, nws xav tias yuav muaj ntau cov qauv microcavity zoo thiab ua haujlwm tau zoo, uas muaj peev xwm zoo hauv kev txhawb nqa kev tshawb fawb yooj yim thiab kev siv tswv yim.
