Urukurikirane rw'amakuru arambuye y'urumuri: Intangiriro kuri Semiconductor Optical Amplifier

Amplifier y'urumuriurukurikirane: Intangiriro kuri Amplifier y'amajwi ya Semiconductor

Amplifier y'urumuri rwa semiconductor(SOA) ni amplifier y'urumuri ishingiye ku buryo bwo gupima urumuri. Mu by'ukuri imeze nk'umuyoboro wa laser wa fibre coupled semiconductor, hamwe n'indorerwamo ya nyuma yasimbuwe na filime irwanya reflective; Tilted waveguides zishobora gukoreshwa mu kugabanya reflectivity y'iherezo. Urumuri rw'ibimenyetso akenshi rwoherezwa binyuze muri waveguide ya semiconductor single-mode, ifite uburebure bwa 1-2 μ m n'uburebure bwa 0.5-2 mm. Uburyo bwa waveguides buhurirana cyane n'agace gakora (amplification), gakoreshwa n'umuyoboro w'amashanyarazi. Injecting current ikora ubucucike runaka bw'umuyoboro w'amashanyarazi mu gice cyo kuyobora, bigatuma habaho impinduka z'urumuri kuva ku gice cyo kuyobora urumuri kugera ku gice cyo kuyobora cy'amashanyarazi. Inyongera ntarengwa iba ku ngufu za photon zirenze gato ingufu za bandgap.

Ihame ry'imikorere ya amplifier y'urumuri rwa semiconductor
Amplifier optique ya semiconductor (SOA) byongera ibimenyetso by'urumuri binyuze mu ibyuka bishyushye, kandi imikorere yabyo ni imwe n'iya laser za semiconductor.SOA optique amplifierni laser ya semiconductor gusa idafite igisubizo, kandi ingenzi yayo ni ukubona inyungu y'urumuri binyuze mu guhindura umubare w'uduce iyo amplifier ya semiconductor optique ikoreshejwe optique cyangwa amashanyarazi.
Ubwoko bwaSOA Semiconductor optique amplifier
Dukurikije uruhare rwa SOA muri sisitemu z'abakiriya, zishobora kugabanywamo ibyiciro bine: serial, booster, switching SOA, na preamplifier.
1. Kwinjizwa mu buryo butaziguye: kwiyongera cyane, Psat iri hagati; NF yo hasi na PDG yo hasi, akenshi bifitanye isano na SOA yigenga ya polarization.
2. Inyongeramusaruro: Psat iri hejuru, kwiyongera guke, akenshi biterwa na polarization;
3. Guhindura: igipimo cyo kurimbuka kiri hejuru kandi igihe cyo kuzamuka/kugwa cyihuta;
4. Pre amplifier: ikwiriye intera ndende yo kohereza ubutumwa, NF iri hasi, no kwiyongera cyane.
Ibyiza bya amplifier optique ya SOA Semiconductor
Inyungu y'urumuri itangwa na SOA muri bandwidth ntabwo ishingiye ku burebure bw'urumuri rw'ikimenyetso cy'urumuri.
Shyira ingufu z'amashanyarazi nk'ikimenyetso cy'ipompo cyazamuwe, aho gushyiramo ingufu z'amashanyarazi.
Bitewe n'ubunini bwayo buto, SOA ishobora guhuzwa n'ibikoresho byinshi byo gufotora bya waveguide kuri substrate imwe igaragara.
4. Bakoresha ikoranabuhanga rimwe na lazeri za diode.
SOA ishobora gukora mu migozi y'itumanaho ya 1300 nm na 1550 nm, ifite umuyoboro wagutse (kugeza kuri 100 nm).
6. Bishobora gushyirwaho kandi bigashyirwa hamwe kugira ngo bikore nk'ibitera imbaraga mbere y'igihe ku mpera y'icyuma gikira urumuri.
SOA ishobora gukoreshwa nk'irembo ryoroshye rya logic muri WDM optique networks.

Imbogamizi za amplifier optique ya SOA Semiconductor
SOA ishobora gutanga ingufu z'amashanyarazi zigera kuri miliwati icumi (mW), ubusanzwe zihagije mu miyoboro imwe mu miyoboro y'itumanaho rya fiber optique. Ariko, sisitemu za WDM zishobora gukenera ingufu zigera kuri mW nyinshi kuri buri muyoboro.
2. Bitewe no guhuza imiyoboro y'amashanyarazi yinjira mu tumashini twa SOA duvanze no hanze yatwo akenshi bigatera gutakaza ikimenyetso, SOA igomba gutanga inyungu y'amashanyarazi kugira ngo igabanye ingaruka z'iki gihombo ku bice by'amashanyarazi yinjira/asohoka mu gace gakora.
SOA irushaho kugira ingaruka ku buryo ibimenyetso by'urumuri byinjira mu kirere bihinduka.
4. Bitera urusaku rwinshi mu byuma bikora kurusha fibre amplifiers.
Iyo imiyoboro myinshi y'urumuri yongerewe uko bikenewe muri porogaramu za WDM, SOA izatera ibiganiro bikomeye.
