Umxholo kunye nokuhlelwa kwe-nanolasers

I-Nanolaser iluhlobo lwesixhobo esincinci esincinci kunye ne-Nano esenziwe ngezixhobo ezifana ne-nanomine njengomnxibelelanisi kwaye ikhuphe i-leser phantsi komfanekiso okanye umculo wombane. Ubungakanani bale glass zihlala zikhulu kuphela imicrons okanye amashumi eeMicrons, kwaye i-Diameter ixhomekeke kumyalelo we-nanometer, eyinxalenye ebalulekileyo yokubonisa ifilimu yexesha elizayo, izinto ezidibeneyo kunye nezinye amasimi.

Ukuhlelwa kwe-nanolaser:

I-1. NguNowiner Laser

Ngo-2001, abaphandi kwiYunivesithi yaseCalifornia, iBerkey, eUnited States, benza i-lamer yeHlabathi yeHlabathi - i-nanolasers-kwi-Nanooptic wire kuphela ubude beenwele zomntu. Le glaser ayikhupheli kuphela i-israviolet i-leasers, kodwa inakho ukuthathwa kwi-Emit Lasers isuka eluhlaza okwesibhakabhaka kwi-ultraviolet enzulu. Abaphandi basebenzise ubume benqanaba eliqhelekileyo obizwa ngokuba yi-Epipahytahytahytahytahytahytahytahytahytahytahytahytay ukwenza i-laser kwiikristasi ezicocekileyo ze-ninc. Bona kuqala "bayalityalela" i-dayires dasires, oko kukuthi, yenziwe kwi-golide kwi-20nm ukuya kwi-15nm ukuya kwi-150nm ukuya kwi-100nm kwaye ubude be-10,000 ye-NM nyu. Ke, xa abaphandi basebenzela i-shistali ye-binc ecocekileyo kwi-nanowisines phantsi kwe-greenhouse, i-chinc ecocekileyo ye-chinc ekhupha i-trystal ye-17NM kuphela. Ezo zinto zinjalo zinokusetyenziselwa ukuchonga iikhemikhali kunye nokuphucula ubungakanani bobuchule beediski zekhompyuter kunye neekhompyuter zephototoic.

I-2. Ultraviolet Nanolaser

Emva kokufika kwe-Micro-i-Lasers, i-leard-diski yediski ye-Micro-I-Micro-I-Ivam ye-Avalanche Lasers, i-chemist yang peidong kunye noogxa bakhe kwiDyunivesithi yaseCalifornia, iBerkey, benza i-nanolasers ye-nanolasers ye-nanolasers. Le nto i-zinc axide i-nanolaser inokukhupha i-laser nge-twidth engaphantsi kwe-0.3nm kunye ne-355NM kunye ne-385NM kwi-38NMNT ye-laser ephantsi, ethathwa njengeyona nto incinci yehlabathi kunye nesixhobo sokuqala esisebenzayo sisebenzisa i-nanotechnology. Kwinqanaba lokuqala lophuhliso, abaphandi baxela kwangaphambili ukuba le nto i-Zno Nanolaser ilula ukwenza, ukuqaqamba okuphezulu, ubungakanani obukhulu, kwaye ilunge ngakumbi kune-Gan Debrs i-van aluhlaza. Ngenxa yobuchule bokwenza uluhlu oluninzi lwee-Nanow noNofires, i-ZnoOlasers zinokufaka izicelo ezininzi ezingenakwenzeka ngezixhobo zanamhlanje. Ukwenzela ukukhulisa ezo bazo, i-Zno Nanofire idityaniswe yindlela yokuthuthwa kwegesi ye-pitalyzs enesitayile se-pitaltial pitaltal. Okokuqala, i-sapfire distate idityaniswe nomaleko we-1 NM ~ 3.5nm ifilimu yegolide, emva koko ibeka kwisikhephe se-Alumna, umbandela kunye ne-F ~ 905 ° C kwi-Ammonia ihambile kwi-subser. I-Nanoigs ye-2μ1 ~ I-8μm kunye nendawo yecandelo le-hexagonal ivelisiwe kwinkqubo yokukhula kwe-2min ~ 10min. The researchers found that ZnO nanowire forms a natural laser cavity with a diameter of 20nm to 150nm, and most (95%) of its diameter is 70nm to 100nm. Ukufundisisa ukhuphelo lweentsuku ezikhutshiweyo, abaphandi baphose isampulu kwi-Greenhouse enezinto ezinobungozi kwi-ND: I-Yag Laser (i-16NM yavent). Ngexesha lokuzivelela kwendalo ekhutshwayo, ukukhanya kukhanyiswe ngokunyuka kwamandla empompo. Xa ukumiselwa kungagqitha umbundu we-Zno Nanowire (malunga ne-40kw / CM), owona msebenzi uphakamileyo uya kuvela kwi-Em Acncesm. Ububanzi bemigca yezi zinto ziphezulu zingaphantsi kwe-0.3NM, ezingaphezulu kwe-1/50 ngaphantsi kobubanzi bomgca ovela kwi-vertex ekhuphayo ngezantsi komda. Ezi zinto zincinci ze-emxiw kunye nokunyuka okukhawulezayo kubuchule bokuphuma kukhokelela kubaphandi ukugqiba kwelokuba kuphumelwe kuphuma kwezi mzuzo. Ke ngoko, uluhlu lwe-nanowreare lunokusebenza njenge-resonator yendalo kwaye ke ibe ngumthombo ofanelekileyo omncinci omncinci. Abaphandi bakholelwa ukuba le mfutshane ye-saveengthdthththth yasetyenziswa kumacandelo okwenza ikhompyutha, ukugcinwa kolwazi kunye neNanoanalyzer.

I-3. Iithamsali kakuhle

Ngaphambi nasemva ko-2010, ilayini yobubanzi i-semiconductor chip iya kufikelela kwi-100nm okanye ngaphantsi, kwaye kuya kuba ngaphantsi, kwaye kuya kubakho kuphela i-elektroni kuphela ehamba kwisekethe, kwaye kuya kubakho igalelo elisebenzayo ekusebenzeni kwesekethe. Ukusombulula le ngxaki, ubungakanani be-lars kakuhle bazalwa. Ngoomatshini be-QUMUM, intsimi enokubakho inyanzela intshukumo ye-elektroni kwaye imiza ibizwa ngokuba yi-quem kakuhle. Esi sithintelo samanani sisetyenziselwa ukwenza amanqanaba amandla amandla asebenzayo kwi-Semiconductor Laser, ukuze inguqu ye-elektroniki phakathi kwamanqanaba e-laser, eyi-rightum kakuhle. Zimbini iintlobo zexabiso kakuhle: I-Traim Liners I-Lasers kunye ne-Dot ye-Dot.

① Umgca we-TIMOUM

Izazinzulu ziphuhlise ii-wiors ze-wiom ze-wire ezinamaxesha ayi-1 000 ngaphezulu kuneendlela zemveli, zithatha inyathelo elikhulu ekudaleni izixhobo ezikhawulezayo kunye nezixhobo zonxibelelwano. I-laser, enokwandisa isantya seaudio, ividiyo, i-intanethi kunye nezinye iindlela zonxibelelwano malunga nenethiwekhi ye-fiber-optic kwi-jersey kwi-jerdey kwi-jerden, iJamani. Ezi zilopheli zinamandla aphezulu ziya kunciphisa isidingo semfuno ephosakeleyo, ezifakwe kuyo yonke i-80km (i-50 yeekhilomitha) kumgca wonxibelelwano, kwakhona ukuvelisa i-larser (iphindayo).
