Uburyo bwo gukoresha amplifier y'urumuri rwa semiconductor

Uburyo bwo gukoreshaamplifier y'urumuri rw'ibice bibiri(SOA) ni ibi bikurikira:

Amplifier ya optique ya SOA semiconductor ikoreshwa cyane mu nzego zose z'ubuzima. Imwe mu nganda z'ingenzi ni itumanaho, rihabwa agaciro mu miyoboro no mu guhinduranya amakuru.SOA semiconductor optique amplifierikoreshwa kandi mu kongera cyangwa kongera ubushobozi bw'amajwi mu itumanaho rya fibre optique ryo kure kandi ni amplifier y'ingenzi cyane.

Intambwe z'ibanze zo gukoresha

Hitamo ibikwiyeSOA optique amplifier: Hashingiwe ku bintu byihariye bikoreshwa n'ibisabwa, hitamo amplifier ya SOA ifite ibipimo bikwiye nko gukora ku bunini bw'umurambararo, kwiyongera, imbaraga zuzuye zo gusohora, n'umubare w'urusaku. Urugero, muri sisitemu z'itumanaho rya optique, niba hagomba gukorwa amplifier y'ibimenyetso muri bande ya 1550nm, amplifier ya SOA ifite ubunini bw'umurambararo bukora hafi y'ubu bwoko bw'umurambararo igomba gutoranywa.

Huza inzira y'urumuri: Huza impera yinjiye ya amplifier ya SOA semiconductor optical amplifier ku isoko y'ibimenyetso by'urumuri bigomba kongerwamo imbaraga, hanyuma uhuze impera y'urumuri n'inzira y'urumuri ikurikiraho cyangwa igikoresho cy'urumuri. Mu gihe uhuza, witondere uburyo fibre optical ikorana kandi ugerageze kugabanya igihombo cy'urumuri. Ibikoresho nka fibre optic couplers na optical isolators bishobora gukoreshwa mu kunoza imikoranire y'inzira y'urumuri.

Shyiraho umuyoboro wa bias: Genzura inyungu ya amplifier ya SOA uhindura umuyoboro wayo wa bias. Muri rusange, uko umuyoboro wa bias uba munini, ni ko inyungu iba nyinshi, ariko icyarimwe, bishobora gutuma urusaku rwiyongera n'impinduka mu mbaraga z'umusaruro wuzuye. Agaciro gakwiye k'umuyoboro wa bias gakwiye kuboneka hashingiwe ku bisabwa nyabyo n'ibipimo by'imikorere byaAmplifier ya SOA.

Gukurikirana no guhindura: Mu gihe cyo gukoresha, ni ngombwa kugenzura imbaraga z'urumuri, kwiyongera, urusaku n'ibindi bipimo bya SOA mu gihe nyacyo. Hashingiwe ku bisubizo by'igenzura, umuvuduko w'amashanyarazi n'ibindi bipimo bigomba guhindurwa kugira ngo harebwe imikorere ihamye n'ubwiza bw'ikimenyetso cya SOA semiconductor optical amplifier.

Ikoreshwa mu buryo butandukanye bwo gukoresha

Sisitemu y'itumanaho ry'amajwi

Amplifier y'ingufu: Mbere yuko ikimenyetso cy'urumuri gitangwa, amplifier y'urumuri ya SOA ishyirwa ku mpera y'urumuri kugira ngo yongere imbaraga z'ikimenyetso cy'urumuri kandi yongere intera yo kohereza ya sisitemu. Urugero, mu itumanaho rya fibre y'urumuri ikora kure, kongera ibimenyetso by'urumuri binyuze muri amplifier y'urumuri ya SOA bishobora kugabanya umubare w'ibiro by'urumuri.

Amplifier y'umurongo: Mu mirongo yo kohereza amakuru hakoreshejwe optique, SOA ishyirwa mu byiciro bimwe na bimwe kugira ngo yishyure igihombo giterwa no kugabanuka kwa fibre n'ibihuza, bityo bigatuma ibimenyetso by'urumuri birushaho kuba byiza mu gihe cyo kohereza amakuru hakoreshejwe intera ndende.

Preamplifier: Ku mpera yo kwakira, SOA ishyirwa imbere y'icyuma gifata urumuri nk'icyuma gifata urumuri mbere yo kongera ubushobozi bw'icyuma gifata urumuri no kunoza ubushobozi bwacyo bwo kubona ibimenyetso by'urumuri bidakomeye.

2. Sisitemu yo kumenya ibintu

Muri demodulator ya fibre Bragg grating (FBG), SOA yongera ikimenyetso cy’urumuri kuri FBG, ikagenzura icyerekezo cy’ikimenyetso cy’urumuri binyuze mu cyuma gipima urumuri, kandi ikumva impinduka mu bunini bw’urumuri cyangwa igihe cy’ikimenyetso cy’urumuri giterwa n’impinduka z’ubushyuhe cyangwa imbaraga. Mu gupima no gupima urumuri (LiDAR), amplifier ya SOA optique ya narrowband, iyo ikoreshejwe hamwe na laser za DFB, ishobora gutanga imbaraga nyinshi zo gupima intera ndende.

3. Guhindura uburebure bw'umuraba

Guhindura uburebure bw'umuraba bigerwaho hakoreshejwe ingaruka zitari umurongo umwe nka cross-gain modulation (XGM), cross-phase modulation (XPM), na four-wave mixing (FWM) bya SOA optical amplifier. Urugero, muri XGM, urumuri rudakomeye rwo kubona umuraba n'urumuri rukomeye rw'umuraba bishyirwa icyarimwe muri SOA optical amplifier. Pompe irahindurwa igashyirwa ku rumuri rwo kubona binyuze muri XGM kugira ngo igere ku ihinduka ry'umuraba.

4. Imashini itanga impumuro y'amajwi

Mu miyoboro y'itumanaho ya OTDM yihuta cyane, imiyoboro ya laser ifite uruziga rwa fiber irimo SOA optical amplifier ikoreshwa mu gukora imiyoboro ishobora guhindurwa mu buryo bwihuse. Mu guhindura ibipimo nk'umuyoboro wa bias wa SOA amplifier n'umuvuduko wa modulation wa laser, umusaruro wa optical pulses z'uburebure butandukanye n'umuvuduko wo gusubiramo ushobora kugerwaho.

5. Gusubiza isaha y'urumuri (optical clock recovery)

Muri sisitemu ya OTDM, isaha ikurwa mu bimenyetso by’umuvuduko mwinshi bya optique binyuze mu mizunguruko ifunze neza hamwe n’amajwi akoreshwa hakoreshejwe amplifier ya SOA. Ikimenyetso cy’amakuru cya OTDM gihuzwa n’indorerwamo y’impeta ya SOA. Urukurikirane rw’amajwi akoreshwa mu kugenzura imikorere y’impeta rukorwa na laser ikoreshwa mu guhindura uburyo bwo gufunga ruyobora indorerwamo y’impeta. Ikimenyetso cy’impeta kiboneka hakoreshejwe photodiode. Impeta ya oscillator igenzurwa na voltage (VCO) ifunze ku muvuduko w’ibanze w’ikimenyetso cy’amakuru yinjira binyuze mu muzunguruko ufunze neza, bityo bigatuma isaha iboneka neza.
