Ikipe y'Abanyamerika yasabye uburyo bushya bwo gutunganya microdisk lasers

Itsinda ry'abashakashatsi rihuriweho mu ishuri ry'ubuvuzi rya Harvard (HMS) na mit ibitaro rusange bya mit bivuga ko bageze ku buryo bwo guhuza imishinga microdisk bakoresheje uburyo bwa pec. "

Mu murima waNanophotonicsna Biomedicine, microdisklasersna Nanodisk Lasers yabaye ikizereisoko yorohejen'ibikorwa. Mubyinshi mubisabwa nko gutumanaho bya chipnic, kuri on-chip bitera amakuru, hamwe no gutunganya amakuru ya photon, bakeneye kugera kuri laser bisohoka muburyo bwuzuye bwuzuyemo kandi ultra-ifunganye bandi Ariko, birakomeje kuba ingorabahizi gukora microdisk na Nanodisk lassers yikirubuga nyabwo ku rugero runini. Inzira ya NofaBriciation iriho imenyekanisha kuri Disiki Diameter, bituma bigorana kubona uburebure bwakozwe na laserUbuvuzi bwa OpToelectronicYateje imbere tekinike ya OCTOCEMIKA (Pec) ifasha guhuza neza uburebure bwa laser bwumuraba bwa microdisk laser hamwe na subnonometer ari ukuri. Akazi kasohotse mu kinyamakuru Fonesics yateye imbere.

Amafoto ya Photochemical
Nk'uko amakuru abitangaza, uburyo bushya bw'amakipe butuma gukora micro-disiki lasers na Nanodisk laser bikomeza uburebure nyabwo, bwateganijwe mbere. Urufunguzo rwiki gice ni ugukoresha pec etching, bitanga inzira nziza kandi nziza yo guhuza neza uburebure bwa microdisc laser. Mubisubizo byavuzwe haruguru, ikipe yabonye neza ibishamium gallium arsenide ya fosifari yashizwemo silica kumurongo winkingi zayo. Bahise bahuza laser walsele yuburebure bwa microdistes neza kumpamyabumenyi yagenwe mugukora amafoto ya Photochemical mu gisubizo cyacukuwe na aside sulfuric.
Bakoze ubushakashatsi kandi bukomeye bwa fotochemike (pec). Hanyuma, bimuriye microdisk-yateguwe microdisk yaka kuri subrate ya polydimethlsiloxane kugirango itange ibice byigenga, byitaruye hamwe na laser laser yuburebure bwa laser bwa laser. Microdisk yavuyemo yerekana ultra-fafrif bandwidth ya laser imyuka, hamwe nalaserKu nkingi munsi ya 0.6 nm hamwe nigice cyitaruye munsi ya 1.5 nm.

Gufungura Urugi na Biomedical Porogaramu
Iki gisubizo gikingura umuryango wa NanoPhotonics nyinshi na biomedical. Kurugero, guhagarara-bonyine microdisk basanzwe bakoresha nka barcode ya fiziki kubijyanye nicyitegererezo cyibinyabuzima. Rero, ubwoko buke bwihariye bwihariye bushobora kwandikwa icyarimwe. Ibinyuranye, ultra-inanga-inanga yamashanyarazi ya microdisk laser izashobora kumenya ubwoko bwinshi bwakagari icyarimwe.
Ikipe yageragejwe kandi yerekana neza imiterere microdisk laser ya laser nka banyanyabuto, kubikoresha kuri label isanzwe ya posika Hamwe na ultra-fagitire impfa mbonera, aba laser bashobora guhinduranya ibinyabuzima, bakoresheje tekinike yagaragaye kandi bafite optique nka cytodynamic imaging, gutembera bya cytometry, hamwe nisesengura ryahanitse. Ikoranabuhanga rishingiye kuri Pec Etching yerekana iterambere rinini muri microdisk lasers. Gutandukanya uburyo, kimwe na precision ya subnanometer, bifungura uburyo bushya bwo gusaba bitabarika muri NORSAPhotoniya hamwe nibikoresho bibuzima, kimwe na barcodes kubikoresho byihariye hamwe na molekile yisesengura.
