Microcavity complex lasers kuchokera kumayiko osokonezeka

Laser wamba amakhala ndi zinthu zitatu zofunika: gwero la mpope, sing'anga yopeza yomwe imakulitsa cheza chokondoweza, komanso kapangidwe kamene kamatulutsa kuwala. Pamene patsekeke kukula kwalaserili pafupi ndi mlingo wa micron kapena submicron, yakhala imodzi mwazofukufuku zomwe zikuchitika panopa m'magulu a maphunziro: ma lasers a microcavity, omwe amatha kukwaniritsa kuwala kwakukulu ndi kuyanjana kwa zinthu pang'ono. Kuphatikiza ma microcavities ndi machitidwe ovuta, monga kubweretsa malire osagwirizana kapena osokonezeka, kapena kuyambitsa zofalitsa zovuta kapena zosalongosoka zogwira ntchito mu microcavities, zidzakulitsa kuchuluka kwa ufulu wa laser. Makhalidwe osakhala a cloning a ma cavities osokonekera amabweretsa njira zambiri zowongolera za magawo a laser, ndipo amatha kukulitsa kuthekera kwake kogwiritsa ntchito.

Mitundu yosiyanasiyana yamasewerama microcavity lasers
Papepalali, ma lasers opangidwa mwachisawawa amasiyanitsidwa kuchokera kumitundu yosiyanasiyana kwa nthawi yoyamba. Kusiyanitsa kumeneku sikumangowonetsa mawonekedwe apadera a laser microcavity mu miyeso yosiyanasiyana, komanso kumveketsa ubwino wa kusiyana kwa kukula kwa microcavity m'magawo osiyanasiyana olamulira ndi ogwiritsira ntchito. The atatu-dimensional solid-state microcavity nthawi zambiri amakhala ndi voliyumu yaying'ono, motero amapeza kuwala kwamphamvu ndi kulumikizana kwa zinthu. Chifukwa cha mawonekedwe ake otsekedwa katatu, malo ounikira amatha kukhala m'madera atatu, nthawi zambiri amakhala ndi khalidwe lapamwamba (Q-factor). Makhalidwewa amachititsa kuti ikhale yoyenera kumveka bwino kwambiri, kusungirako photon, kukonza chidziwitso cha quantum ndi zina zamakono zamakono. Kanema wotseguka wazithunzi ziwiri zoonda ndi nsanja yabwino yopangira mapulani osasinthika. Monga ndege ya dielectric yokhala ndi mbali ziwiri yokhala ndi phindu lophatikizika ndi kubalalitsidwa, kachitidwe kakanema kakang'ono kamatha kutenga nawo gawo pakupanga laser mwachisawawa. Planar waveguide effect imapangitsa kulumikizana kwa laser ndikusonkhanitsa kukhala kosavuta. Ndi kukula kwa patsekeke kumachepetsedwa, kuphatikizika kwa mayankho ndikupeza media mu gawo limodzi la ma waveguide kumatha kupondereza kuwala kwa ma radial kuwala kwinaku kukulitsa kumveka kwa kuwala kwa axial ndi kulumikizana. Njira yophatikizirayi pamapeto pake imapangitsa kuti pakhale luso la kupanga laser ndi kulumikizana.

Makhalidwe owongolera a ma lasers a random microcavity
Zizindikiro zambiri zama lasers azikhalidwe, monga kulumikizana, poyambira, mayendedwe otuluka ndi mawonekedwe a polarization, ndiye njira yayikulu yoyezera momwe ma laser amagwirira ntchito. Poyerekeza ndi ma lasers ochiritsira omwe ali ndi ma symmetric cavities okhazikika, laser microcavity laser imapereka kusinthasintha kwakukulu mu malamulo a parameter, omwe amawonekera mumiyeso yambiri kuphatikizapo nthawi, domain domain ndi spatial domain, ndikuwunikira kuwongolera kosiyanasiyana kwa laser microcavity laser.

Makhalidwe ogwiritsira ntchito ma lasers osasintha a microcavity
Kugwirizana kwapang'onopang'ono kwapang'onopang'ono, kusakhazikika kwachisawawa komanso kukhudzidwa kwa chilengedwe kumapereka zinthu zambiri zabwino zogwiritsira ntchito ma stochastic microcavity lasers. Ndi yankho la kuwongolera mode ndi kuwongolera mayendedwe a laser mwachisawawa, gwero lapadera lowunikirali limagwiritsidwa ntchito kwambiri pojambula, kuzindikira zachipatala, kumva, kulumikizana zidziwitso ndi magawo ena.
Monga chisokonezo yaying'ono cavity laser pa yaying'ono ndi nano sikelo, mwachisawawa microcavity laser ndi tcheru kwambiri kusintha kwa chilengedwe, ndi makhalidwe parametric angayankhe zosiyanasiyana tcheru zizindikiro kuwunika chilengedwe kunja, monga kutentha, chinyezi, pH, madzi ndende, refractive index, ndi zina zotero, kupanga nsanja yapamwamba yodziwira ntchito zomvera kwambiri. M'munda wa kujambula, zabwinogwero lowalakuyenera kukhala ndi kachulukidwe kowoneka bwino, kutulutsa kolimba kolowera ndi kulumikizana pang'ono kwa malo kuti apewe kusokoneza kwa mawanga. Ofufuzawo adawonetsa zabwino za ma lasers osasinthika pazithunzi zaulere mu perovskite, biofilm, zomwaza makristalo amadzimadzi komanso zonyamula ma cell. Pozindikira zachipatala, laser microcavity laser imatha kunyamula zidziwitso zobalalika kuchokera kwachilengedwe, ndipo idagwiritsidwa ntchito bwino kuti izindikire mitundu yosiyanasiyana yazachilengedwe, yomwe imapereka mwayi wopezeka ndi matenda osasokoneza.

M'tsogolomu, kusanthula mwadongosolo kamangidwe ka microcavity kosasinthika ndi njira zovuta zopangira laser kudzakhala kokwanira. Ndi kupita patsogolo kosalekeza kwa sayansi ya zida ndi nanotechnology, zikuyembekezeredwa kuti ma microcavity ena abwino komanso osagwira ntchito apangidwe, omwe ali ndi kuthekera kwakukulu pakupititsa patsogolo kafukufuku wofunikira komanso kugwiritsa ntchito bwino.
