Ni gute amplifier y'amashanyarazi ya semiconductor igera ku kwiyongera?

Bigenda biteamplifier y'urumuri rw'ibice bibirikugera ku kongera ubushobozi?

Nyuma y’igihe cy’itumanaho rya fibre optique rinini, ikoranabuhanga ryo kongera ingufu ry’amashanyarazi ryateye imbere vuba.Amplifiers z'urumurikongera ibimenyetso by'urumuri bishingiye ku mirasire ishyushye cyangwa gukwirakwira kw'urumuri. Dukurikije ihame ry'imikorere, amplifiers z'urumuri zishobora kugabanywamo amplifiers z'urumuri za semiconductor (SOAnaamplifier za fibre optiqueMuri bo,amplifiers za semiconductor optiquezikoreshwa cyane mu itumanaho ry’urumuri bitewe n’inyungu zo kugira umugozi munini, guhuza neza no kuba uburebure bw’urumuri rwinshi. Zigizwe n’uturere dukora n’utwo tudakora, kandi akarere gakora ni akarere gakora. Iyo ikimenyetso cy’urumuri kinyuze mu gace gakora, gituma electron zitakaza ingufu zigasubira ku butaka mu buryo bwa fotoni, zifite uburebure bumwe n’ubw’urumuri, bityo zikongera ikimenyetso cy’urumuri. Amplifier y’urumuri rwa semiconductor ihindura semiconductor carrier mu gice cy’inyuma cy’umuyoboro w’amashanyarazi, yongera uburebure bw’urumuri rw’imbuto zashyizwemo, kandi ikomeza imiterere y’ibanze y’urumuri rw’imbuto rwashyizwemo nk’ikwirakwizwa, ubugari bw’umurongo n’inshuro. Uko umuriro ukora wiyongera, imbaraga z’urumuri zisohoka nazo ziyongera mu mibanire runaka y’imikorere.

Ariko uku kwiyongera ntigufite imipaka, kuko amplifiers za semiconductor optical amplifiers zifite ikintu cyo gupima ubushobozi bw'amashanyarazi. Iki kintu kigaragaza ko iyo imbaraga z'amashanyarazi zinjira zihoraho, kwiyongera kwiyongera kwiyongera k'umubare w'amashanyarazi ushyirwamo, ariko iyo umubare w'amashanyarazi ushyizwemo ari munini cyane, kwiyongera kw'amashanyarazi kuzagabanuka cyangwa kugabanuka. Iyo uburemere bw'amashanyarazi ashyirwamo buhoraho, imbaraga zisohoka ziyongera uko imbaraga z'amashanyarazi ziyongera, ariko iyo imbaraga z'amashanyarazi zinjira ari nyinshi cyane, igipimo cy'ikoreshwa ry'amashanyarazi giterwa n'imirasire ishyushye kiba kinini cyane, bigatuma kwiyongera kw'amashanyarazi cyangwa kugabanuka. Impamvu y'ikibazo cyo kwiyongera kw'amashanyarazi ni imikoranire hagati ya elektroni na fotoni mu bikoresho by'akarere bikora. Byaba fotoni zikorwa mu buryo bwo gupima ubushobozi bw'amashanyarazi cyangwa fotoni zo hanze, igipimo cy'imirasire ishyushye ikoresha ibikoresho bijyana n'igipimo cy'amashanyarazi asubiramo ku rwego rw'ingufu zijyanye n'igihe. Uretse imirasire ishyushye, igipimo cy'amashanyarazi gikoreshwa n'ibindi bintu nacyo kirahinduka, ibyo bigira ingaruka mbi ku kwiyongera kw'amashanyarazi.

Kubera ko akazi k'ingenzi ka amplifiers optical amplifiers ari linear amplification, ahanini kugira ngo igere ku amplification, ishobora gukoreshwa nk'amplifiers power, line amplifiers na preamplifiers muri sisitemu y'itumanaho. Ku mpera yo kohereza, amplifiers optical amplifier ikoreshwa nk'amplifiers power kugira ngo yongere imbaraga zisohoka ku mpera yo kohereza ya sisitemu, bishobora kongera cyane intera yo kohereza ya relay y'umuzingo wa sisitemu. Mu murongo wo kohereza, amplifiers optical amplifier irashobora gukoreshwa nk'amplifiers optique, kugira ngo intera yo kohereza isubira inyuma yongere yongererweho ku buryo butunguranye. Ku mpera yo kwakira, amplifiers optical amplifier irashobora gukoreshwa nk'amplifiers optique, bishobora kunoza cyane uburyo bwo kwakira. Imiterere y'ubwiyongere bw'ubwiyongere bw'amplifiers optical amplifiers zituma inyungu kuri biti ifitanye isano n'uruhererekane rwa biti rwabanje. Ingaruka hagati y'imiyoboro mito ishobora kandi kwitwa cross-gain modulation effect. Ubu buryo bukoresha impuzandengo y'ibarurishamibare y'ingaruka zo kohereza hagati y'imiyoboro myinshi kandi bugashyiramo umuraba uhoraho w'imbaraga ziciriritse muri gahunda kugira ngo ukomeze urumuri, bityo ugabanye inyungu rusange ya amplifier. Hanyuma ingaruka zo kohereza hagati y'imiyoboro ziragabanuka.

Amplifiers za semiconductor optical zifite imiterere yoroshye, zoroshye guhuza, kandi zishobora kongera ibimenyetso by'urumuri bitandukanye, kandi zikoreshwa cyane mu guhuza ubwoko butandukanye bwa laser. Kuri ubu, ikoranabuhanga ryo guhuza laser rishingiye kuri amplifiers za semiconductor optical rikomeje gukura, ariko haracyakenewe imbaraga muri ibi bintu bitatu bikurikira. Kimwe ni ukugabanya igihombo cyo guhuza na fiber optique. Ikibazo nyamukuru cya amplifiers za semiconductor optique ni uko igihombo cyo guhuza na fiber ari kinini. Kugira ngo hongerwe imikorere myiza yo guhuza, lens ishobora kongerwa kuri sisitemu yo guhuza kugira ngo igabanye igihombo cyo kwerekana, inoze uburinganire bw'imirasire, kandi igere ku guhuza neza. Icya kabiri ni ukugabanya ubushobozi bwo guhuza bwa amplifiers za semiconductor optique. Ikiranga polarization ahanini kivuga ku buryo urumuri rw'impanuka rushobora kugabanuka. Iyo amplifiers za semiconductor optique zidatunganyijwe byumwihariko, bandwidth nziza y'inyungu izagabanuka. Imiterere y'amazi ya quantum ishobora kunoza neza uburyo amplifiers za semiconductor optique zihagaze neza. Birashoboka kwiga imiterere y'amazi ya quantum yoroshye kandi ihanitse kugira ngo ugabanye ubushobozi bwo guhuza bwa amplifiers za semiconductor optique. Icya gatatu ni ugutunganya inzira ihuriweho. Muri iki gihe, guhuza amplifiers za semiconductor optical na lazers biragoye cyane kandi biragoye mu gutunganya tekiniki, bigatuma habaho igihombo kinini mu kohereza ibimenyetso by'urumuri no gutakaza igikoresho, kandi ikiguzi ni kinini cyane. Kubwibyo, dukwiye kugerageza kunoza imiterere y'ibikoresho bihujwe no kunoza imiterere y'ibikoresho.

Mu ikoranabuhanga ry'itumanaho rikoresha optique, ikoranabuhanga ryo kongera ingufu mu ikoranabuhanga ni rimwe mu ikoranabuhanga rifasha, kandi ikoranabuhanga rya optique amplifier riri gutera imbere cyane. Muri iki gihe, imikorere ya optique amplifier ya semiconductor yarushijeho kuba myiza cyane, cyane cyane mu iterambere ry'ikoranabuhanga rishya rya optique nka wavelength division multiplexing cyangwa optique switching modes. Hamwe n'iterambere ry'inganda z'amakuru, ikoranabuhanga ryo kongera ingufu mu ikoranabuhanga rikwiriye imigozi itandukanye n'ikoreshwa ritandukanye rizatangizwa, kandi iterambere n'ubushakashatsi ku ikoranabuhanga rishya bizatuma ikoranabuhanga rya optique amplifier ya semiconductor rikomeza gutera imbere no gutera imbere.
