An kirkiro Lasers na tsaye na waje a tsakiyar shekarun 1990 don shawo kan ci gaban wata matsala ta al'ada: Yadda za a samar da haɓakar Laseronductor na gargajiya na semicains tare da ingancin katako mai kyau a yanayin yanayi mai sauƙi.
Vertical mai rufin waje na saman-itar (vecsels), wanda kuma aka sani daLabarun Dokokin Diskortor(SDL), sabon memba ne na dangin Laser. Zai iya tsara igiyar ruwa ta hanyar canza tsarin abu da kuma kauri daga cikin Quantum da kyau a matsakaici kusurwar kusurwar Laler. An tattara maimaitawar laseran Laser ɗin da ke ƙasa na co guntu da madogara ta waje. Wannan tsari na rarrabuwa na waje yana ba da damar shigar da abubuwan gani a cikin kogon don aiwatar da irin aiki irin wannan sau ɗaya, bambancin mita, da kuma kulle-kullewa, yin vecsel mai kyauLaser sourceDon aikace-aikacen aikace-aikace daga biophotonics, Spectroscopy,Laser magani, da tsarin laser, da Laser.
Mai riƙewa na VC-farfajiya LasicondCorctor Lasondectors ne inda yankin ya nuna shi, da fitowar ta hanyar lalacewa, kamar yadda aka nuna a kan tsari mai lalacewa, kuma in mun gwada da sauki tsari tsari. Yana nuna kyakkyawan aiki a aikace-aikacen na laser nuni, da ta dace sadarwa da kuma duba agogo. Koyaya, vcsels ba zai iya samun laƙeran wuta sama da matakin watt ba, don haka ba za a yi amfani da su a cikin filayen tare da babban iko.

Laser mai resonator na VCSEL yana haɗuwa da rarraba ɓoyayyen mai tunani (DBR) da aka haɗa da tsarin kayan aikin semiconduttor na sama da ƙananan yanki, wanda ya sha bamban daLaserresonator ya ƙunshi jirgin sama mai laushi a cikin Eel. The direction of the VCSEL optical resonator is perpendicular to the chip surface, the laser output is also perpendicular to the chip surface, and the reflectivity of both sides of the DBR is much higher than that of the EEL solution plane.
Tsawon resonator na VCSEL yana da sauran 'yan microns, wanda yafi karami fiye da na hanyar milloret na Eel, da kuma hanyar hanya ɗaya da oscillation samu daga cikin rami ya ragu. Kodayake ana iya samun fitarwa na yanayin yanayin ƙasa, fitarwa na fitarwa na iya isa ga milliwuwts da yawa. Lauyoyin fitarwa na kayan fitarwa Lacsel Biyayi ne, kuma kusurwar rarraba tana da yawa karami fiye da na gefen walkiya na gefen katako. Don cimma nasarar fitowar wutar lantarki ta VCSEL, ya zama dole don haɓaka yankin mai haske don samar da ƙarin riba, da kuma karuwar yankin mai haske zai haifar da fitarwa Laser-yanayin fitarwa. A lokaci guda, yana da wuya a sami allurar sutura a cikin yankin mai haske mai zurfi, amma vCSEL na iya fitarwa lokacin fitarwa na yau da kullun.
