Nanolaser yog ib hom micro thiab nano ntaus ntawv uas yog ua los ntawm nanomaterials xws li ib tus resonator thiab tuaj yeem tawm laser hauv kev yees duab lossis cov hluav taws xob. Qhov loj ntawm cov laser no feem ntau tsuas yog ntau pua ntawm microns lossis txawm tias yog qhov tseem ceeb ntawm cov duab sib dhos, thiab cov kab ke ntawm lub neej tom ntej, thiab Optics thiab lwm daim teb.
Kev faib tawm Nanoliber:
1. Nanowire laser
Xyoo 2001, cov kws tshawb nrhiav ntawm University of California, Berkeley, nyob rau Tebchaws Meskas, tsim lub ntiaj teb me tshaj plaws laser - ntawm cov nanooptic hlau tsuas yog ib txhiab ntawm tib neeg cov plaub hau. Cov laser no tsuas yog emits ultraviolet lasers, tab sis kuj tseem tuaj yeem raug tso tawm los ntawm cov nyom ntawm xiav kom tob ultraviolet. Cov kws tshawb nrhiav tau siv cov txheej txheem qauv uas tau hu ua Oriented Epiphytation los tsim lub laser los ntawm cov ntshiab zinc oxide muaju. Lawv thawj zaug "kev coj ua" Nanowes, uas yog, tsim nyob rau ntawm ib txheej kub nrog ib lub cheeb ntawm 20nm txog 10,000 nm ntshiab zinc ox oxide cov xov. Tom qab ntawd, thaum cov kws tshawb nrhiav tau ua kom cov ntshiab zinc oxide crystals nyob rau lwm lub laver hauv tsev cog khoom, cov muaj qab hau Xws li cov neeg nanolasers tuaj yeem siv los txheeb xyuas cov tshuaj thiab txhim kho cov ntaub ntawv kom muaj peev xwm ntawm lub computer disks thiab photo computers.
2. Ultraviolet nanolaser
Ua raws li kev tawm tsam ntawm micro-lasers, micro-lub nplhaib lasers, thiab noobm-ensigues, No zinc oxide nanolaser tuaj yeem tawm lub laser nrog ib kab ntawm cov nyom ntawm lub ntiaj teb thiab ib qho ntawm thawj cov ntaub ntawv siv tau siv Nanotechnology. Nyob rau hauv thawj theem ntawm kev txhim kho, cov kws tshawb nrhiav kwv yees tau tias no zno Nanolaser yooj yim rau kev tsim khoom, siab loj, thiab kev ua yeeb yam yog sib npaug lossis zoo dua li gan cov khau khiab xiav. Vim tias muaj peev xwm ua kom muaj zog ua kom muaj zog nanowire arrays, zno nanolasers tuaj yeem nkag tau ntau daim ntawv thov uas tsis tuaj yeem ua tau nrog lub gaas li niaj hnub no. Txhawm rau kom loj hlob xws li lasers, zno nanowire yog synthesized los ntawm cov roj av thauj khoom uas catalyzes Epitaxial Crystal kev loj hlob. Ua ntej, sapphire substrate yog coated nrog ib txheej ntawm 1 nf ~ 3.5nm tow zaj duab xis, thiab tom qab ntawd muab tso rau ntawm lub nkoj almina, thiab tom qab ntawd cov ntaub ntawv zn no, thiab tom qab ntawd ZN chav yuav thauj mus rau substrate. Nanowires ntawm 2μm ~ 10μm nrog rau kev hla hla kev sib tw tau tsim tawm hauv cov txheej txheem kev loj hlob ntawm 2min ~ 10min. Cov kws tshawb nrhiav pom tias Zno Nanowire ua lub ntuj Laser kab noj hniav nrog ib lub cheeb ntawm 20nm txog 150nm, thiab feem ntau (95%) ntawm nws lub taub yog 70nm rau 100nm. Txhawm rau kawm qhov kev tso tawm ntawm lub nanowires, cov kws tshawb nrhiav tau siv tus qauv hauv lub tsev cog khoom ntawm ND: YAG Laser (26ns mem tes dav). Thaum lub sijhawm hloov kho ntawm lub emission spectrum, lub teeb yog tau teeb nrog kev nce ntawm lub zog tso kua mis. Thaum lub lasing ntau dua qhov pib ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno ntawm zno nongowire (txog 40kW / cm), qhov siab tshaj plaws yuav tshwm sim hauv lub emission spectrum. Cov kab dav ntawm cov ntsiab lus siab tshaj plaws yog tsawg dua 0.3nm, uas yog ntau tshaj li 1/50 tsawg dua li cov kab dav los ntawm emission for epission. Cov kab no nqaim thiab nce qib sai sai hauv kev siv emission kom xaus lus tau tshwm sim hauv cov nanowires. Yog li ntawd, cov nanowire array tuaj yeem ua raws li lub ntuj resonator thiab yog li ua ib qho zoo tagnrho micro laser peev txheej. Cov kws tshawb nrhiav ntseeg tias qhov luv-wavelength anolaser tuaj yeem siv nyob rau hauv liaj teb optical xam, cov ntaub ntawv cia thiab nanoanalyzer.
3. Quantum Zoo Lasers
Ua ntej thiab tom qab xyoo 2010, tus kab dav etched on sacruit Coec yuav ncav cuag cov hluav taws xob, thiab tsawg dua thiab txo qis kev cuam tshuam rau kev ua haujlwm ntawm Circuit Court. Txhawm rau kom daws tau cov teeb meem no, Quantum zoo lasers tau yug los. Nyob rau hauv quantum mechanics, ib tug muaj peev xwm hais tias constrains cov lus tsa suab ntawm cov electrons thiab Quantizes lawv tau hu ua Qua QEEM. Qhov QUAN CALLTTET yog siv los ua cov qoj ib txwm txheej ntawm lub zog hluav taws xob ntawm lub zog hluav taws xob ntawm lub laser, uas yog QUAN, uas yog QEATUM zoo lier. Muaj ob hom QUAUM WEL LASS: Quantum Kab Lasers thiab Quantum Dot lasers.
① Quantum kab laser
Cov kws tshawb fawb tau tsim cov Quantum hlau xaim hlau uas yog 1,000 zaus muaj zog dua li cov roj av thiab cov khoom siv sib txuas lus sai sai. Lub laser, uas tuaj yeem nce cov ceev ntawm cov suab, video, internet thiab lwm yam kev sib txuas lus ntawm cov tswv yim fiber ntau, Cov nyiaj lasers siab dua yuav txo tau cov kev xav tau rau cov rov qab ua dua, uas tau teeb tsa txhua 80km (50 mais) raws li kev sib txuas lus laser uas tsis tshua muaj zog tshaj li lawv taug kev los ntawm cov fiber (rov ua dua).
