Njira yogwiritsira ntchitosemiconductor kuwala amplifier(SOA) ili motere:
SOA semiconductor optical amplifier imagwiritsidwa ntchito kwambiri m'mbali zonse za moyo. Imodzi mwamafakitale ofunikira kwambiri ndi matelefoni, omwe amayamikiridwa pakuwongolera ndikusintha.SOA semiconductor Optical amplifierAmagwiritsidwanso ntchito kukulitsa kapena kukulitsa kutulutsa kwa ma siginecha atalitali optical fiber communications ndipo ndiyofunikira kwambiri amplifier ya kuwala.
Masitepe oyambira ogwiritsa ntchito
Sankhani yoyeneraSOA Optical amplifier: Kutengera zochitika ndi zofunikira pakugwiritsa ntchito, sankhani SOA Optical amplifier yokhala ndi magawo oyenera monga kutalika kwa mafunde, kupindula, mphamvu zotulutsa zodzaza ndi phokoso. Mwachitsanzo, m'makina olankhulirana owoneka bwino, ngati kukulitsa kwa siginecha kuyenera kuchitika mu gulu la 1550nm, SOA Optical amplifier yokhala ndi mawonekedwe ogwiritsira ntchito pafupi ndi izi iyenera kusankhidwa.
Lumikizani njira ya kuwala: Lumikizani mapeto olowera a SOA semiconductor optical amplifier ku gwero la optical signal lomwe liyenera kukulitsidwa, ndikugwirizanitsa mapeto otuluka ku njira yotsatira ya kuwala kapena chipangizo cha kuwala. Mukalumikiza, tcherani khutu pakugwirizanitsa bwino kwa fiber optical ndikuyesera kuchepetsa kutayika kwa kuwala. Zipangizo monga ma fiber optic couplers ndi optical isolator atha kugwiritsidwa ntchito kukhathamiritsa njira zolumikizirana.
Khazikitsani tsankho lapano: Yesetsani kupindula kwa amplifier ya SOA posintha kukondera kwake komweko. Nthawi zambiri, kukondera kokulirapo, kumapindulitsa kwambiri, koma panthawi imodzimodziyo, kungayambitse kuwonjezereka kwa phokoso ndi kusintha kwa mphamvu yotulutsa mphamvu. Kukondera koyenera komwe kulipo pakali pano kumayenera kupezeka potengera zofunikira zenizeni komanso magawo a magwiridwe antchito aSOA amplifier.
Kuyang'anira ndi kusintha: Panthawi yogwiritsira ntchito, ndikofunikira kuyang'anira mphamvu ya kuwala, phindu, phokoso ndi zina za SOA panthawi yeniyeni. Malingana ndi zotsatira zowunikira, zokondera zamakono ndi zina ziyenera kusinthidwa kuti zitsimikizire kuti ntchito yokhazikika ndi khalidwe la chizindikiro cha SOA semiconductor optical amplifier.
Kugwiritsiridwa ntchito muzochitika zosiyanasiyana zogwiritsira ntchito
Njira yolumikizirana ndi Optical
Amplifier yamagetsi: Chizindikiro cha kuwala chisanaperekedwe, SOA semiconductor optical amplifier imayikidwa pamapeto otumizira kuti iwonjezere mphamvu ya chizindikiro cha kuwala ndikuwonjezera mtunda wotumizira dongosolo. Mwachitsanzo, mukulankhulana kwakutali kwa fiber fiber, kukulitsa ma sign optical kudzera pa SOA semiconductor optical amplifier kumatha kuchepetsa kuchuluka kwa masiteshoni otumizirana mauthenga.
Line amplifier: M'mizere yotumizira kuwala, SOA imayikidwa pazigawo zina kuti ipereke malipiro otayika chifukwa cha fiber attenuation ndi zolumikizira, kuonetsetsa ubwino wa zizindikiro za kuwala panthawi yopita mtunda wautali.
Preamplifier: Pamapeto olandira, SOA imayikidwa kutsogolo kwa wolandira kuwala monga preamplifier kuti apititse patsogolo chidziwitso cha wolandira ndikuwongolera luso lake lozindikira zizindikiro zofooka za kuwala.
2. Optical kuzindikira dongosolo
Mu fiber Bragg grating (FBG) demodulator, SOA imakweza chizindikiro cha kuwala kwa FBG, imayendetsa kayendetsedwe ka chizindikiro cha kuwala kupyolera mu circulator, ndikuwona kusintha kwa kutalika kwa mawonekedwe kapena nthawi ya chizindikiro cha kuwala komwe kumachitika chifukwa cha kutentha kapena kusiyana kwa zovuta. Pozindikira kuwala ndi kuyambira (LiDAR), narrowband SOA Optical amplifier, ikagwiritsidwa ntchito limodzi ndi ma lasers a DFB, imatha kupereka mphamvu zotulutsa zambiri kuti zizindikire mtunda wautali.
3. Wavelength kutembenuka
Kutembenuka kwa Wavelength kumatheka pogwiritsa ntchito zotsatira zopanda malire monga cross-gain modulation (XGM), cross-phase modulation (XPM), ndi four-wave mixing (FWM) ya SOA Optical amplifier. Mwachitsanzo, mu XGM, kuwala kofooka kosalekeza kosalekeza ndi kuwala kwamphamvu kwapampu kumabayidwa nthawi imodzi mu SOA Optical amplifier. Pampuyo imasinthidwa ndikuyika ku kuwala kodziwikiratu kudzera mu XGM kuti ikwaniritse kutembenuka kwa wavelength.
4. Kuwala kugunda jenereta
M'malo olumikizirana othamanga kwambiri a OTDM wavelength division multiplexing, ma laser ring ring laser okhala ndi SOA Optical amplifier amagwiritsidwa ntchito kupanga ma pulse obwerezabwereza othamanga kwambiri. Mwa kusintha magawo monga bias current ya SOA amplifier ndi ma frequency modulation a laser, kutulutsa kwa ma pulses optical of different wavelengths ndi ma frequency obwerezabwereza amatha kutheka.
5. Kuwala koloko kuchira
Mu dongosolo la OTDM, wotchiyo imapezedwanso kuchokera ku ma siginecha othamanga kwambiri kudzera pa malupu otsekedwa ndi gawo ndi masiwichi owunikira omwe akhazikitsidwa kutengera amplifier ya SOA. Chizindikiro cha data cha OTDM chikuphatikizidwa ndi galasi la mphete la SOA. Mawonekedwe a optical control pulse opangidwa ndi laser mode-locked laser amayendetsa galasi la mphete. Chizindikiro chotuluka cha galasi la mphete chimadziwika ndi photodiode. Mafupipafupi a oscillator-controlled oscillator (VCO) amatsekedwa pamafupipafupi omwe amalowetsa deta kudzera mu chipika chotsekedwa ndi gawo, potero amapeza kuwala kwa wotchi.
