Enhanced semiconductor Optical amplifier

Enhancedsemiconductor optical amplifier

Iyo yakagadziridzwa semiconductor optical amplifier ishanduro yakakwidziridzwa ye semiconductor optical amplifier (SOA Optical amplifier) Iyo amplifier inoshandisa semiconductors kupa iyo yepakati yekuwana. Chimiro chayo chakafanana neicho cheFabry-Pero laser diode, asi kazhinji chiso chekupedzisira chinoputirwa nefirimu rinopesana nereflection. Iyo yazvino dhizaini inosanganisira anti-reflection mafirimu pamwe neanotemerwa waveguides uye hwindo matunhu, ayo anogona kuderedza kumagumo kwechiso kutaridzika kusvika pazasi 0.001%. High-performance enhanced optical amplifiers inonyanya kubatsira pakusimudza (optical) zviratidzo, sezvo pane kutyisidzira kwakakomba kwekurasikirwa kwechiratidzo panguva yekufambisa kure-kure. Sezvo chiratidzo chemaziso chakanyatso kukwidziridzwa, nzira yechinyakare yekuishandura kuita chiratidzo chemagetsi isati yave isina basa. Saka, kushandiswa kweSOAinovandudza zvakanyanya kutapurirana zvakanaka. Iyi tekinoroji inowanzo shandiswa kupatsanura simba uye kurasikirwa muripo muWDM network.

Maitiro ekushandisa

Mune optical fiber kutaurirana masisitimu, semiconductor optical amplifiers (SOA) inogona kushandiswa munzvimbo dzakawanda dzekushandisa kusimudzira kuita uye kutapurirana chinhambwe chehurongwa hwekutaurirana. Izvi zvinotevera mamwe maapplication akajairika ekushandisa SOA amplifier mune optical fiber kutaurirana masisitimu:

Preamplifier: SOAOptical amplifierinogona kushandiswa sepreamplifier pamagumo ekugamuchira optical mumasisitimu ekutaurirana akareba ane optical fibers anopfuura 100 kilometers, kuwedzera kana kuwedzera simba rekubuda kwechiratidzo mumasisitimu ekureba optical fiber communication system, nekudaro kuripa chinhambwe chisina kukwana chekufambisa chinokonzerwa nekubuda kusina simba kwezviratidzo zvidiki. Uyezve, SOA inogonawo kushandiswa kushandisa optical network signal regeneration tekinoroji mune optical fiber communication systems.

All-optical signal regeneration: Mune optical network, sezvo kureba kwekufambisa kunowedzera, zviratidzo zvemaziso zvichaderera nekuda kwekudzivirira, kupararira, ruzha, nguva yejitter uye crosstalk, nezvimwewo. Nokudaro, mukufambisa kwemarefu-kure, zvakakosha kubhadhara zviratidzo zvemaziso zvakaora kuti zvive nechokwadi chechokwadi chemashoko ekufambisa. All-optical sign regeneration inoreva kukwidziridza, kuumbazve uye kugadzirisa nguva. Kumwe kukwidziridzwa kunogona kuitwa nemaoptical amplifiers akadai semiconductor optical amplifiers, EDFA uye Raman amplifiers (RFA).

Mune optical fiber sensing masisitimu, semiconductor optical amplifiers (SOA amplifier) inogona kushandiswa kukwidziridza masaini masaini, nekudaro ichiwedzera kunzwa uye kurongeka kwema sensors. Izvi zvinotevera mamwe maapplication akajairika ekushandisa SOA mune optical fiber sensing masisitimu:

Optical fiber strain kuyerwa: Gadzirisa iyo optical fiber pane chinhu chine dhizaini inoda kuyerwa. Kana chinhu chacho chiri pasi pekutambudzika, kuchinja kwehutano kunokonzera kuchinja kuduku muhurefu hwefiber optical, nokudaro kushandura wavelength kana nguva yechiratidzo chemaziso kune PD sensor. SOA amplifier inogona kuwana yakakwirira sensing kuita nekusimudzira uye kugadzirisa chiratidzo chemaziso.

Optical fiber pressure measurement: Nekubatanidza optical fibers ne-pressure-sensitive materials, kana chinhu chiri pasi pekumanikidzwa, chinokonzera kuchinja mukurasikirwa kwemaziso mukati me optical fiber. SOA inogona kushandiswa kukwidziridza iyi isina kusimba chiratidzo chemaziso kuti iwane yakanyanya kusimba kuyera kuyerwa.

Iyo semiconductor optical amplifier SOA chinhu chakakosha muminda ye optical fiber communication uye optical fiber sensing. Nekukudza uye kugadzirisa masaini masaini, inosimudzira mashandiro ehurongwa uye kunzwa kwekunzwa. Aya maapplication akakosha pakuwana yakakwirira-kumhanya, yakagadzikana uye yakavimbika optical fiber kutaurirana pamwe nekunyatso uye inoshanda optical fiber sensing.
