Intangiriro kuri laser ya semiconductor isohora ubuso buhagaze (VCSEL)

Intangiriro yo gusohora imbunda mu cyuho gihagazelaser ya semiconductor(VCSEL)
Imashini zisohora ubuso zikoresheje imirasire y'inyuma y'izuba zakozwe hagati mu myaka ya 1990 kugira ngo zikemure ikibazo cy'ingenzi cyabangamiye iterambere rya laser zisanzwe za semiconductor: uburyo bwo gukora imashini zisohora laser zifite imbaraga nyinshi zifite ubwiza bwo hejuru mu buryo bw'ibanze bwo gusimbuka.
Imirasire isohora ubuso bw'inyuma ihagaze (Vecsels), izwi kandi nkalaser za disiki za semiconductor(SDL), ni abanyamuryango bashya mu muryango wa laser. Ishobora gushushanya uburebure bw'umuraba ihindura imiterere y'ibikoresho n'ubugari bw'amazi ya quantum mu gice cyo gukuraho ingufu za semiconductor, kandi hamwe no kongeramo imbaraga za intracavity bishobora gutwikira uburebure bwinshi bw'umuraba kuva kuri ultraviolet kugeza kuri infrared kure, bigatuma habaho imbaraga nyinshi mu gihe igumana uburebure buke bwa Angle circular symmetric laser beam. Resonator ya laser igizwe n'imiterere ya DBR yo hasi ya gain chip n'indorerwamo yo hanze ihuza umusaruro. Iyi miterere yihariye ya resonator yo hanze yemerera ibintu by'urumuri kwinjiza mu mwobo kugira ngo bikoreshwe nko kongeramo imbaraga za frequency, itandukaniro rya frequency, no gufunga mode, bigatuma VECSEL iba nziza cyane.isoko ya laserku bikorwa bitandukanye kuva kuri biophotonics, spectroscopy,umuti wa laser, n'icyerekezo cya laser.
Resonator ya laser ya semiconductor isohora urumuri ya VC-surface igororotse ku ruhande rw'aho agace gakora kari, kandi urumuri rwayo rugaragara ku ruhande rw'agace gakora, nk'uko bigaragara ku ishusho.VCSEL ifite ibyiza bidasanzwe, nko kuba ntoya, inshuro nyinshi, ubwiza bw'imirasire, urwego runini rw'ibyangiritse ku buso, hamwe n'uburyo bworoshye bwo kuyikora. Igaragaza imikorere myiza mu gukoresha laser ecran, optique communication na optique clock. Ariko, VCsel ntishobora kubona lasers zifite imbaraga nyinshi zirenze urugero rwa watt, bityo ntizishobora gukoreshwa mu bintu bifite ingufu nyinshi.

Resonator ya laser ya VCSEL igizwe na Bragg reflector (DBR) igizwe n'imiterere ya epitaxial y'ibikoresho bya semiconductor ku mpande zombi zo hejuru n'izo hasi z'akarere gakora, bitandukanye cyane n'imiterere yabyo.laserresonator igizwe n'umurongo ucagaguye muri EEL. Icyerekezo cya resonator ya VCSEL optique gihagaze neza ku buso bwa chip, umusaruro wa laser nawo uhagaze neza ku buso bwa chip, kandi ubwiza bw'impande zombi za DBR buri hejuru cyane ugereranije n'ubw'umurongo wa EEL.
Uburebure bwa resonator ya laser ya VCSEL muri rusange ni mikoroni nke, nto cyane ugereranyije n’iya milimetero resonator ya EEL, kandi inyungu imwe iboneka binyuze mu guhindagurika k’umuyoboro w’amashanyarazi mu mwobo ni nto. Nubwo umusaruro w’ibanze wa transverse mode ushobora kugerwaho, imbaraga zo gusohora zishobora kugera kuri miliwati nyinshi gusa. Imiterere y’uruhererekane rw’imirasire ya laser ya VCSEL ni uruziga, kandi inguni y’itandukaniro ni nto cyane ugereranyije n’iya laser isohora impande. Kugira ngo VCSEL igere ku mbaraga nyinshi, ni ngombwa kongera akarere k’urumuri kugira ngo itange inyungu nyinshi, kandi kwiyongera k’akarere k’urumuri bizatuma laser isohora iba umusaruro w’uburyo bwinshi. Muri icyo gihe, biragoye kugera ku ishyirwa ry’umuyoboro umwe mu gace kanini k’urumuri, kandi ishyirwa ry’umuyoboro utaringaniye rizongera ubwinshi bw’ubushyuhe. Muri make, VCSEL ishobora gusohora ahantu h’ibanze h’uruziga rw’uburyo bungana binyuze mu gishushanyo mbonera cy’imiterere, ariko imbaraga zo gusohora ziba nke iyo umusaruro ari umwe. Kubwibyo, VCsel nyinshi zikunze gushyirwa mu buryo bwo gusohora.
