Ma laser a Microcavity complex ochokera ku mayiko olamulidwa kupita ku mayiko osakhazikika

Laser wamba imakhala ndi zinthu zitatu zofunika: gwero la pampu, chowonjezera mphamvu chomwe chimakulitsa mphamvu ya kuwala, ndi kapangidwe ka m'mimba komwe kamapanga kuwala kwa kuwala. Pamene kukula kwa m'mimba mwalaserIli pafupi ndi mulingo wa micron kapena submicron, yakhala imodzi mwa malo ofufuzira omwe alipo pakali pano m'gulu la ophunzira: ma laser a microcavity, omwe amatha kukwaniritsa kulumikizana kwakukulu kwa kuwala ndi zinthu pang'onopang'ono. Kuphatikiza ma microcavity ndi machitidwe ovuta, monga kuyika malire osakhazikika kapena osakhazikika, kapena kuyika zida zogwirira ntchito zovuta kapena zosakhazikika mu ma microcavity, kudzawonjezera ufulu wa kutulutsa kwa laser. Makhalidwe osapanga ma cloning a ma disordered cavities amabweretsa njira zowongolera zambiri za ma laser, ndipo amatha kukulitsa kuthekera kwake kogwiritsa ntchito.

Machitidwe osiyanasiyana a mwachisawawama laser a microcavity
Mu pepalali, ma laser a microcavity osasinthika amagawidwa kuchokera ku miyeso yosiyanasiyana ya cavity koyamba. Kusiyana kumeneku sikungowonetsa mawonekedwe apadera a laser ya microcavity yosasinthika m'miyeso yosiyanasiyana, komanso kumafotokoza bwino ubwino wa kusiyana kwa kukula kwa microcavity yosasinthika m'magawo osiyanasiyana olamulira ndi ogwiritsira ntchito. Microcavity ya ma three-dimensional solid-state nthawi zambiri imakhala ndi voliyumu yaying'ono, motero imapangitsa kuti kuwala ndi zinthu zikhale zolimba. Chifukwa cha kapangidwe kake kotsekedwa ka ma three-dimensional, gawo la kuwala limatha kugawidwa kwambiri m'magawo atatu, nthawi zambiri ndi chinthu chapamwamba (Q-factor). Makhalidwe amenewa amawapangitsa kukhala oyenera kuzindikira bwino, kusungira photon, kukonza zambiri za quantum ndi madera ena apamwamba aukadaulo. Dongosolo lotseguka la filimu yopyapyala ya ma thin ndi nsanja yabwino yopangira nyumba zopyapyala zosasinthika. Monga ndege ya dielectric yosasinthika ya ma divi awiri yokhala ndi gain and scattering yophatikizika, dongosolo lopyapyala la filimu limatha kutenga nawo mbali popanga laser yosasinthika. Mphamvu ya planar waveguide imapangitsa kuti kulumikizana ndi kusonkhanitsa kwa laser kukhale kosavuta. Pamene kukula kwa cavity kwachepetsedwa kwambiri, kuphatikiza kwa mayankho ndi zolumikizira zamagetsi mu wowongolera wa mafunde a mbali imodzi kumatha kuletsa kufalikira kwa kuwala kwa radial pomwe kumawonjezera mphamvu ya kuwala kwa axial ndi kulumikizana. Njira yolumikizira iyi pamapeto pake imawongolera bwino kupanga ndi kulumikizana kwa laser.

Makhalidwe olamulira a ma lasers a microcavity osasinthika
Zizindikiro zambiri za ma laser achikhalidwe, monga mgwirizano, malire, njira yotulutsira, ndi makhalidwe a polarization, ndizofunika kwambiri poyesa magwiridwe antchito a ma laser. Poyerekeza ndi ma laser achikhalidwe omwe ali ndi ma cavity okhazikika, laser ya random microcavity imapereka kusinthasintha kwakukulu pakulamulira ma parameter, komwe kumawonetsedwa m'magawo angapo kuphatikiza nthawi, malo owonera ndi malo owonera, zomwe zikuwonetsa kulamulira kwamitundu yambiri kwa laser ya random microcavity.

Makhalidwe ogwiritsira ntchito ma lasers a microcavity mwachisawawa
Kugwirizana kochepa kwa malo, kusasinthika kwa njira ndi kukhudzidwa ndi chilengedwe kumapereka zinthu zambiri zabwino zogwiritsira ntchito ma laser a stochastic microcavity. Ndi yankho la njira yowongolera ndi kuwongolera kwa laser yachisawawa, gwero lapaderali la kuwala likugwiritsidwa ntchito kwambiri mu kujambula zithunzi, kuzindikira matenda, kuzindikira, kulumikizana ndi chidziwitso ndi madera ena.
Monga laser yosokonezeka ya micro-cavity pamlingo wa micro ndi nano, laser ya random microcavity imakhudzidwa kwambiri ndi kusintha kwa chilengedwe, ndipo makhalidwe ake a parametric amatha kuyankha zizindikiro zosiyanasiyana zobisika zomwe zimayang'anira chilengedwe chakunja, monga kutentha, chinyezi, pH, kuchuluka kwa madzi, refractive index, ndi zina zotero, zomwe zimapangitsa kuti pakhale nsanja yabwino kwambiri yogwiritsira ntchito high-sensitivity sensitivity sensitivity applications. Mu gawo la kujambula, njira yabwino kwambirigwero la kuwalaiyenera kukhala ndi kuchuluka kwa ma spectral, kutulutsa kwamphamvu kolunjika komanso mgwirizano wochepa wa malo kuti ipewe kusokoneza kwa ma speckle. Ofufuzawa adawonetsa ubwino wa ma laser osasinthika pa kujambula kwa speckle mu perovskite, biofilm, liquid crystal scatterers ndi maselo onyamula minofu. Pa matenda azachipatala, laser ya random microcavity imatha kunyamula zambiri zofalikira kuchokera kwa wolandira wachilengedwe, ndipo yagwiritsidwa ntchito bwino kuti izindikire minofu yosiyanasiyana yachilengedwe, zomwe zimapangitsa kuti matenda asamalowe m'malo mwawo.

Mtsogolomu, kusanthula mwadongosolo kwa kapangidwe ka microcavity yosakhazikika komanso njira zovuta zopangira laser kudzakhala kokwanira kwambiri. Ndi kupita patsogolo kosalekeza kwa sayansi ya zinthu ndi nanotechnology, zikuyembekezeredwa kuti kapangidwe ka microcavity yosakhazikika komanso yogwira ntchito bwino kadzapangidwa, komwe kuli ndi kuthekera kwakukulu kolimbikitsa kafukufuku woyambira ndi ntchito zothandiza.
