Amplifier y'urumuri rwa semiconductor ni iki?

Ni ikiamplifier y'urumuri rw'ibice bibiri

Amplifier y'urumuri rwa semiconductor ni ubwoko bwa amplifier y'urumuri ikoresha uburyo bwo gukusanya urumuri bwa semiconductor. Imeze nka diode ya laser, aho indorerwamo iri ku mpera yo hasi isimbuzwa irangi rigaragaza urumuri. Urumuri rw'ikimenyetso runyuzwa muri waveguide ya semiconductor imwe. Ingano y'urumuri rwa waveguide ni mikorometero 1-2 kandi uburebure bwarwo buri kuri mm 0.5-2. Uburyo bwa waveguide bufite aho buhuriye cyane n'agace ka active (amplification), gakoreshwa n'umuyoboro w'amashanyarazi. Umuyoboro w'amashanyarazi urimo gutera imbaraga runaka mu gice cy'amashanyarazi, bigatuma umuyoboro w'amashanyarazi uhinduka ugana ku gice cy'amashanyarazi cya valence. Inyongera y'umuvuduko iba iyo ingufu za photon zirenze gato ingufu za bandgap. Amplifier y'urumuri ya SOA ikoreshwa muri sisitemu z'itumanaho mu buryo bwa pigtails, ifite uburebure bwa 1300nm cyangwa 1500nm, itanga hafi dB 30.

ItsindaSOA semiconductor optique amplifierni igikoresho cya PN gihuza imiterere y'ikiraro cya quantum. Isura y'inyuma ihindura umubare w'uduce twa dielectric. Nyuma y'uko urumuri rwo hanze rwinjiye, imirasire ishyushye irakorwa, bigatuma ibimenyetso by'urumuri birushaho kwiyongera. Inzira zose eshatu zo kohereza ingufu zibaho muriSOA optique amplifier. Kongera imbaraga z'ibimenyetso by'urumuri bishingiye ku ibyuka bikurura. Uburyo bwo kwinjiza ingufu n'ibyuka bikurura bibaho icyarimwe. Uburyo bwo kwinjiza ingufu z'urumuri rw'ipompe bushobora gukoreshwa mu kwihutisha kugarura ibikoresho, kandi icyarimwe, ipompe y'amashanyarazi ishobora kohereza elektroni ku rwego rwo hejuru rw'ingufu (umurongo wo kuyobora). Iyo imirasire yihuta, izatera urusaku rw'imirasire yihuta. SOA optique amplifier ishingiye kuri chips za semiconductor.

Uduce twa semiconductor tugizwe na semiconductors zigizwe na compound, nka GaAs/AlGaAs, InP/AlGaAs, InP/InGaAsP na InP/InAlGaAs, nibindi. Ibi kandi ni ibikoresho byo gukora semiconductor lasers. Imiterere ya waveguide ya SOA ni imwe cyangwa isa n'iya semiconductors. Itandukaniro riri mu kuba semiconductors zigomba gukora umwobo ukikije gain medium kugira ngo zikore kandi zigumane oscillation y'ikimenyetso cy'urumuri. Ikimenyetso cy'urumuri kizakongerwa inshuro nyinshi mu mwobo mbere yo gusohoka.Amplifier ya SOA(ibyo turimo kuganiraho hano bigarukira gusa ku byuma bitanga umuvuduko w'amazi bikoreshwa mu bikorwa byinshi), urumuri rukenera kunyura mu buryo bwo gukura inshuro imwe gusa, kandi urumuri rwo gusubira inyuma ni ruto. Imiterere ya SOA amplifier igizwe n'uturere dutatu: Agace ka P, Agace ka I (urwego rukora cyangwa urufunguzo), na Agace ka N. Uru rwego rukora ubusanzwe rugizwe na quantum Wells, bishobora kunoza imikorere y'amashanyarazi no kugabanya umuvuduko w'amashanyarazi.

Igishushanyo cya 1: Fiber laser ifite SOA ihuriweho mu gukora imivuduko y'urumuri

Bikoreshwa mu kohereza imiyoboro

Ubusanzwe SOA ntizikoreshwa gusa mu kongera ingufu: zishobora no gukoreshwa mu itumanaho rya fibre optique, porogaramu zishingiye ku nzira zitari umurongo umwe nko kwiyongera k'umuvuduko cyangwa polarization ya cross-phase, zikoresha itandukaniro ry'icyerekezo cy'umuvuduko muri amplifier optique ya SOA kugira ngo zibone indices zitandukanye zo kugarura urumuri. Izi ngaruka zishobora gukoreshwa mu kohereza imiyoboro (guhindura uburebure bw'umuvuduko), guhindura imiterere y'impinduka, kugarura isaha, kongera kugaragara kw'ibimenyetso no kumenya imiterere, n'ibindi muri sisitemu zo gukwirakwiza uburebure bw'umuvuduko.

Bitewe n’iterambere ry’ikoranabuhanga rya optoelectronic integrated circuit hamwe no kugabanya ikiguzi cyo gukora, amashami y’ikoreshwa rya SOA semiconductor optical amplifier nk’ibikoresho by’ibanze by’ikoranabuhanga, ibikoresho bikora neza by’ikoranabuhanga hamwe n’ibice by’ingenzi by’ikoranabuhanga bizakomeza kwaguka.
