Nigute wakoresha semiconductor optique amplifier

Uburyo bwo gukoresha bwasemiconductor optique amplifier(SOA) ni ibi bikurikira:

SOA semiconductor optique amplifier ikoreshwa cyane mubice byose byubuzima. Imwe mu nganda zikomeye ni itumanaho, rifite agaciro muguhindura no guhinduranya.SOA semiconductor optique amplifierikoreshwa kandi mukuzamura cyangwa kwongerera ibimenyetso ibisohoka intera ndende ya optique ya fibre itumanaho kandi ni ngombwa cyane amplifier.

Intambwe yibanze yo gukoresha

Hitamo igikwiyeSOA optique amplifier: Ukurikije ibintu byihariye bisabwa nibisabwa, hitamo SOA optique amplifier ifite ibipimo biboneye nkuburebure bwumurongo wakazi, inyungu, imbaraga zuzuye zuzuye, hamwe n urusaku. Kurugero, muri sisitemu yitumanaho rya optique, niba ibimenyetso byongera ibimenyetso bigomba gukorwa mugice cya 1550nm, amplifier ya SOA optique hamwe nuburebure bwumurongo wegereye iyi ntera igomba guhitamo.

Huza inzira ya optique: Huza iyinjizwa ryanyuma rya SOA semiconductor optique amplifier na optique ya signal ya optique ikeneye kongererwa imbaraga, hanyuma uhuze ibisohoka kurangiza inzira ikurikira cyangwa ibikoresho bya optique. Mugihe uhuza, witondere guhuza imikorere ya fibre optique hanyuma ugerageze kugabanya igihombo cya optique. Ibikoresho nka fibre optique hamwe na optique ya optique irashobora gukoreshwa mugutezimbere inzira nziza.

Shiraho kubogama: Kugenzura inyungu za SOA amplifier muguhindura kubogama kwayo. Muri rusange, uko kubogama kwinshi, niko inyungu ziyongera, ariko mugihe kimwe, birashobora gutuma urusaku rwiyongera nimpinduka mumbaraga zuzuye zuzuye. Agaciro gakwiye kubogamye kugomba kuboneka hashingiwe kubisabwa nyirizina n'ibipimo byaSOA amplifier.

Gukurikirana no guhindura: Mugihe cyo gukoresha, birakenewe gukurikirana ibisohoka imbaraga za optique, inyungu, urusaku nibindi bipimo bya SOA mugihe nyacyo. Ukurikije ibisubizo byakurikiranwe, kubogama kubogamye nibindi bipimo bigomba guhinduka kugirango harebwe imikorere ihamye hamwe nubuziranenge bwibimenyetso bya SOA semiconductor optique amplifier.

Gukoresha muburyo butandukanye bwo gusaba

Sisitemu y'itumanaho ryiza

Imbaraga zongera imbaraga: Mbere yuko ibimenyetso bya optique bitangwa, SOA semiconductor optique amplifier ishyirwa kumpera yohereza kugirango yongere imbaraga za signal optique kandi yongere intera yoherejwe na sisitemu. Kurugero, mumashanyarazi maremare ya optique ya fibre itumanaho, kongera ibimenyetso bya optique binyuze muri SOA semiconductor optique amplifier irashobora kugabanya umubare wibibuga.

Amplifier yumurongo: Mumurongo wohereza optique, SOA ishyirwa mugihe runaka kugirango yishyure igihombo cyatewe na fibre attenuation hamwe na connexion, byemeza ubwiza bwibimenyetso bya optique mugihe cyoherejwe kure.

Preamplifier: Ku iherezo ryakiriwe, SOA ishyirwa imbere ya optique yakira nka preamplifier kugirango yongere ibyiyumvo byabakiriya kandi inoze ubushobozi bwo gutahura ibimenyetso bya optique.

2. Sisitemu yo kumva neza

Muri fibre Bragg grating (FBG) demodulator, SOA izamura ibimenyetso bya optique kuri FBG, igenzura icyerekezo cyikimenyetso cya optique ikoresheje umuzenguruko, kandi ikumva impinduka zuburebure bwumurongo cyangwa igihe cyibimenyetso bya optique biterwa nubushyuhe cyangwa itandukaniro ryimiterere. Mu gutahura urumuri no kuringaniza (LiDAR), umurongo mugari wa SOA optique amplifier, iyo ikoreshejwe ifatanije na laseri ya DFB, irashobora gutanga ingufu zisohoka kugirango tumenye intera ndende.

3. Guhindura umurongo

Guhindura umurongo wa Wavele bigerwaho hifashishijwe ingaruka zidafite umurongo nko guhinduranya inyungu (XGM), guhinduranya ibice (XPM), hamwe no kuvanga imirongo ine (FWM) ya SOA optique amplifier. Kurugero, muri XGM, urumuri rudakomeye rwerekana urumuri rumuri hamwe nurumuri rukomeye rwa pompe rwinjizwa icyarimwe muri SOA optique amplifier. Pompe yahinduwe kandi ikoreshwa kumucyo wo kumenya binyuze muri XGM kugirango uhindure uburebure bwumurongo.

4. Amashanyarazi meza

Mumuvuduko wihuse wa OTDM kugabana kugwiza guhuza itumanaho, uburyo bwo gufunga fibre impeta ya lazeri irimo SOA optique amplifier ikoreshwa kugirango habeho umuvuduko mwinshi wo gusubiramo umuvuduko-muremure. Muguhindura ibipimo nka bias bigezweho bya SOA amplifier hamwe na modulation inshuro ya laser, ibisohoka bya optique ya puls ya optique yuburebure butandukanye hamwe ninshuro zisubiramo birashobora kugerwaho.

5. Kugarura isaha nziza

Muri sisitemu ya OTDM, isaha yagaruwe mubimenyetso byihuta bya optique binyuze mumuzinga ufunze feri na optique ya optique yashyizwe mubikorwa bishingiye kuri amplifier ya SOA. Ikimenyetso cya OTDM gihujwe nindorerwamo ya SOA. Optical control pulse ikurikirana ikorwa nuburyo bushobora gufungwa laser itwara indorerwamo yimpeta. Ibisohoka byerekana indorerwamo yimpeta bigaragazwa na fotodiode. Inshuro ya oscillator igenzurwa na voltage (VCO) ifunze kumurongo wibanze wibimenyetso byinjiza binyuze mumuzinga ufunze, bityo ukagera kumasaha meza.
