Ngwa anya amplifiers na ubi nke ngwa anya fiber nkwurịta okwu

An ngwa anya ampilifayabụ ngwaọrụ na-amụba akara ngosi anya. N'ihe gbasara nzikọrịta ozi fiber optic, ọ na-arụkarị ọrụ ndị a: 1. Ịkwalite ike na imewanye ike anya. Site n'itinye ngwa ngwa anya n'ihu njedebe nke transmitter anya, ike anya na-abanye na eriri nwere ike ịba ụba. 2. Mgbasa ozi ntanetị n'ịntanetị, na-edochi ndị na-emegharị ihe na usoro nkwurịta okwu fiber optic; 3. Preamplification: Tupu onye na-ahụ maka foto na njedebe nnata, a na-ebuli mgbama ọkụ na-adịghị ike iji welie mmetụta nke ịnata.

Ka ọ dị ugbu a, ihe nrịbama ngwa anya nakweere na nzikọrịta ozi fiber Optical gụnyere ụdị ndị a: 1. Semiconductor optical amplifier (SOA Optical amplifier)/Semiconductor laser amplifier (SLA Optical amplifier); 2. Ihe na-eme ka eriri eriri na-adịghị ahụkebe nke ụwa, dị ka ihe na-eme ka eriri bait-doped (EDFA Optical amplifier).

1.Semiconductor optical amplifiers: N'okpuru ọnọdụ ngwa dị iche iche na ntụgharị ihu njedebe dị iche iche, lasers semiconductor nwere ike ịmepụta ụdị dị iche iche nke semiconductor optical amplifiers. Ọ bụrụ na ịnya ụgbọ ala nke laser semiconductor dị ala karịa ọnụ ụzọ ya, ya bụ, ọ nweghị laser emepụtara, n'oge a, a na-etinye akara ngosi anya n'otu njedebe. Ọ bụrụhaala na ugboro nke mgbaàmà anya a dị nso na etiti oghere nke laser, a ga-emewanye ya ma si na njedebe nke ọzọ pụta. Ụdị nke asemiconductor ngwa anya amplifierka a na-akpọ Fabry-Perrop ụdị ihe nrịbawanye anya (FP-SLA). Ọ bụrụ na laser na-eleda anya n'elu ọnụ ụzọ, ntinye mgbaàmà anya na-adịghị ike nke otu ọnọdụ site na otu njedebe, ọ bụrụhaala na ugboro nke mgbaàmà anya dị n'ime ụdị dị iche iche nke laser multimode a, a ga-emewanye mgbama ngwa anya ma kpochie ya na ọnọdụ ụfọdụ. Ụdị ampilifaya anya a ka a na-akpọ ụdị amplifier ekpochi injaction (IL-SLA). Ọ bụrụ na njedebe abụọ nke laser semiconductor na-ekpuchi enyo ma ọ bụ kpochapu ya na oyi akwa nke ihe nkiri na-egbochi ntụgharị uche, na-eme ka ikuku ya dị ntakịrị na enweghị ike ịmepụta oghere Fabry-Perrow resonant, mgbe mgbaàmà anya na-agafe na oyi akwa waveguide na-arụ ọrụ, ọ ga-abawanye mgbe ọ na-eme njem. Ya mere, a na-akpọ ụdị ihe nrịbawanye anya a na-akpọ njem ebili mmiri na-eme njem (TW-SLA), a na-egosikwa usoro ya na foto a. N'ihi na bandwit nke ebili mmiri na-ejegharị ejegharị ụdị ampilifaya anya bụ iwu atọ nke ịdị ukwuu karịa nke ụdị ampilifaya ụdị Fabry-Perot, yana bandwit 3dB ya nwere ike iru 10THz, ọ nwere ike ịbawanye akara ngosi anya nke ugboro dị iche iche ma bụrụ ihe njiri mara ngwa anya nke ukwuu.

2. Bait-doped fiber amplifier: Ọ nwere akụkụ atọ: Nke mbụ bụ eriri doped nwere ogologo sitere na ọtụtụ mita ruo iri iri. Ihe adịghị ọcha ndị a bụ ion ụwa na-adịghị ahụkebe, nke na-etolite ihe eji arụ ọrụ laser; Nke abụọ bụ isi iyi mgbapụta laser, nke na-enye ume nke ogologo wavelength kwesịrị ekwesị iji kpalie ion doped obere ụwa iji nweta mmụba nke ìhè. Nke atọ bụ coupler, nke na-enyere ọkụ mgbapụta na mgbaama ọkụ na di na nwunye n'ime doped optical fiber na-arụ ọrụ. Ụkpụrụ na-arụ ọrụ nke ihe na-amụba eriri fiber yiri nke laser steeti siri ike. Ọ na-eme ka ọnụọgụgụ ọnụọgụgụ ọnụọgụ ego gbanwere n'ime ihe eji arụ ọrụ laser ma na-ebute radieshon kpaliri. Iji mepụta ike urughuru nọmba inversion nkesa ala, ihe karịrị abụọ ume etoju kwesịrị itinye aka na ngwa anya mgbanwe, a atọ-larịị na anọ-larịị usoro, na a na-aga n'ihu ọkọnọ nke ume si a mgbapụta isi iyi. Iji nye ike n'ụzọ dị irè, ogologo ebili mmiri nke foton mgbapụta kwesịrị ịdị mkpụmkpụ karịa nke laser photon, ya bụ, ike nke photon mgbapụta kwesịrị ịdị ukwuu karịa nke laser photon. Ọzọkwa, oghere resonant na-emepụta nzaghachi dị mma, ya mere enwere ike ịmepụta igwe ọkụ laser.

3. Ndị na-emepụta ihe na-emepụta ihe na-adịghị mma: Ma ndị na-emepụta ihe na-emepụta ihe na-emepụta ihe na erbium fiber amplifiers na-adaba n'okpuru ụdị nke fiber amplifiers. Otú ọ dị, nke mbụ na-eji mmetụta na-adịghị ahụ anya nke quartz fibers, ebe nke ikpeazụ na-eji erbium-doped quartz fibers mee ihe na mgbasa ozi na-arụ ọrụ. Nkịtị quartz optical fibers ga-emepụta mmetụta siri ike na-adịghị na ntanetị n'okpuru ọrụ nke ọkụ mgbapụta siri ike nke ogologo ogologo ogologo oge kwesịrị ekwesị, dị ka mkpali agbasa Raman (SRS), kpaliri Brillouin agbasa (SBS), na mmetụta ngwakọta anọ. Mgbe a na-ebufe mgbaàmà n'akụkụ eriri anya yana ọkụ mgbapụta, enwere ike ịbawanye ọkụ mgbaàmà. Ya mere, ha na-etolite fiber Raman amplifiers (FRA), Brillouin amplifiers (FBA), na parametric amplifiers, nke niile na-ekesa eriri amplifiers.

Nchịkọta: Ntuziaka mmepe nke ngwa ngwa niile bụ uru dị elu, ike mmepụta dị elu, na ọnụ ọgụgụ mkpọtụ dị ala.
