Igitekerezo no gushyira mu byiciro bya Nanolasers

Nanolaser ni ubwoko bwa micro na Nano bikozwe muri Nanomarial nka nanowire nkumuvugurura kandi ushobora gusohora laser mumafoto cyangwa amashanyarazi. Ingano yiyi laser ikunze kuba amabuye amagana gusa cyangwa mikorobe, kandi diameter iri kuri gahunda ya Nanometer, nikihe gice cyingenzi cya firime yoroheje izabera, optics.

Ibyiciro bya Nanolaser:

1. Nanowire Laser

Mu 2001, abashakashatsi bo muri kaminuza ya Californiya, Berkeley, muri Amerika, yashyizeho laser ntoya ku isi - Nanolasers - kuri nanoosers igihumbi igihumbi gusa cy'uburebure bw'umusatsi w'umuntu. Iyi laser ntabwo isohora lasers laser, ariko nanone irashobora gutondekwa ko impande ziva mubururu kugeza kuri ultraviolet ndende. Abashakashatsi bakoresheje tekinike isanzwe yitwa epiphytation kugirango ikore laser muri kristu ya zinc. Banza "umuco" Nanowires, ni ukuvuga, yashizweho ku rubura rwa zahabu afite diameter ya 200 ku ya 150nm n'uburebure bwa 10,000 nm een ​​olide insinga. Noneho, mugihe abashakashatsi bakoresheje kristu ya zinc yera muri Nanowires hamwe nundi museri munsi ya parike, nyakatsi ya zinc yasohotse lasel ifite uburebure bwa 17nm gusa. Aba Nanolasers bashoboraga gukoreshwa mukumenya imiti no kunoza ubushobozi bwo kubika amakuru ya disiki ya mudasobwa na mudasobwa za Photonic.

2. Ultraviolet nanolaser

Nyuma yo gukurikira ahitwa micro-lasers, amababi ya micro-micro-impeta, na quanthche lasers, na quiste yangla. Iyi zinc oxide nanolaser irashobora gusohora laser hamwe numurongo utarenze 0.3nm hamwe nuburebure bwa laser ya 355 Mu cyiciro cya mbere cy'iterambere, abashakashatsi bahanuye ko iyi Zno Nanolaser iroroshye gukora, umucyo mwinshi, ubunini buke, kandi imikorere ihwanye cyangwa irusheho kuba nziza. Kubera ubushobozi bwo gukora ubucucike bwa Nanowi arrays, zno Nanolasers irashobora kwinjira muri porogaramu nyinshi zidashoboka hamwe nibikoresho bya Gaaas. Kugirango dukureho amahwemo, Zno Nanowire nuburyo bwo gutwara ibintu catalyes eptalzial sthetal. Ubwa mbere, subshire ya safiro yashizwemo hamwe na firime ya 1 ~ 3.5nm, hanyuma iyashyira mubwato bwa alumina, ibikoresho birashyuha kuri 880 ° C ~ 905 ° Nanonires ya 2μm ~ 10μm hamwe na hexxagonal yambukiranya igice cyatanzwe muburyo bwo gukura bwa 2min ~ 10min. Abashakashatsi basanze Zno Nanowire akora umwobo usanzwe wa laser hamwe na diameter ya 20nm kugeza 150nm, kandi menshi (95%) ya diameter yayo 70nm kugeza 100nm. Kwiga byashishikarije kwa Nanowires, abashakashatsi batandukanya icyitegererezo muri parike hamwe na nyakatsi havuzwe haruguru. Mugihe ubwihindurize bwikigereranyo cyumutse, urumuri rurahamye rwiyongera kubwimbaraga za pompe. Iyo laseni yarenze ku muryango wa Zno Nanowire (hafi 40kw / cm), ingingo ndende izagaragara mu buryo butaramuka. Umurongo wa kabiri wizi ngingo zo hejuru uri munsi ya 0.3nm, zirenze 1/50 munsi yumurongo wimibare ivuye mumyanya ya vertion munsi yumuryango. Iyi ntumbwe Kubwibyo, iyi Nanoonire yakanguye irashobora gukora nkumurongo ka karemano bityo akaba ahinduka isoko nziza ya micro laser. Abashakashatsi bemeza ko uyu muburakari mugufi nanolaser ashobora gukoreshwa mumirima yo kubara neza, kubika amakuru na Nanoanaller.

3. Quanim neza

Mbere na nyuma ya 2010, umugezi wanditseho Chip Semiconductor uzagera kuri 100nm cyangwa munsi yayo, kandi hazabaho electrons nkeya zigenda mumuzunguruko, kandi hazabaho electron nkeya zigenda mumuzunguruko, kandi ubwiyongere bwa electron buzagira ingaruka zikomeye kubikorwa byumuzunguruko. Gukemura iki kibazo, Quanim neza lasers yavutse. Mu mbuka nyinshi, umurima ushobora kuvuguruza icyerekezo cya electrons no kubashyiraho byitwa kafomu neza. Iyi mbogamizi ya Quanim ikoreshwa mugukora ingufu za Quam mu rwego rwa Semiconductor ya semiconductor Hariho ubwoko bubiri bwa foneum exsers: Quanim Line lasers na Quanim dot lasers.

Umurongo wa Quaseri

Abahanga mu bya siyansi batsimbataje insinga za Quamsum zifite imbaraga 1.000 zidashobora kuba intandaro gakondo, zifata intambwe nini yo gushyiraho ibikoresho by'imigabane byihuse. Laser, ishobora kongera umuvuduko w'amajwi, videwo, interineti n'ubundi buryo bwo gutumanaho ku miyoboro ya ya firime, yateguwe na Porotey muri kaminuza ya Yale na Porseck muri Fiziki i Dresden, mu Budage. Izi mpago zisumba izindi zagabanije gukenera kwisubiraho bihenze, zishyirwaho buri 80km (ibirometero 50 kumurongo, byongeye gutanga pasiporo idakabije mugihe banyuze muri fibre (abasubiramo).
