Usoro ihe nrịba elu anya: Okwu Mmalite nke Semiconductor Optical Amplifier

Ngwa ngwa ngwausoro: Okwu Mmalite nke Semiconductor Optical Amplifier

Semiconductor optical amplifier(SOA) bụ ihe nrịba elu anya dabere na mgbasa ozi uru semiconductor. Ọ bụ n'ezie dị ka eriri jikọtara semiconductor laser tube, na njedebe mirror dochie anya ihe nkiri mgbochi; Enwere ike iji ntuziaka ebili mmiri gbadoro anya iji belata nhụsianya njedebe. A na-ebunyekarị ọkụ mgbaama site na otu ụdị ebili mmiri nke otu semiconductor, nwere akụkụ mpụta nke 1-2 μm na ogologo nke ihe dịka 0.5-2mm. Ụdị waveguide na-adaba nke ọma na mpaghara na-arụ ọrụ (amplification), nke ugbu a na-agbapụta. Ịbanye ugbu a na-emepụta ụfọdụ njupụta nke ebu na band conduction, na-enye ohere maka ntụgharị anya site na band conduction gaa na valence band. Uru kachasị na-apụta na ike foton ntakịrị karịa ike bandgap.

Semiconductor Optical amplifiers(SOA) na-amụba akara ngosi ọkụ merenụ site na mkpali na-apụta, na usoro ha bụ otu nke lasers semiconductor.SOA Optical amplifierbụ naanị laser semiconductor na-enweghị nzaghachi, na isi ya bụ inweta uru anya site n'ịgbanwe ọnụọgụ nke irighiri ihe mgbe ejiri anya ma ọ bụ na-agbanye ọkụ eletrik.
Ụdị nkeSOA Semiconductor Optical amplifier
Dị ka ọrụ SOA na-arụ na sistemụ ndị ahịa, enwere ike kewaa ha ụzọ anọ: serial, booster, switching SOA, na preamplifier.
1. Ntinye ntụziaka: uru dị elu, agafeghị oke Psat; NF dị ala na PDG dị ala, na-ejikọta ya na SOA nwere onwe ya.
2. Onye nkwalite: Psat dị elu, uru dị ala, na-adaberekarị na polarization;
3. Gbanwee: oke mbibi dị elu na oge ịrị elu / ọdịda ngwa ngwa;
4. Pre amplifier: adabara maka ogologo nnyefe ogologo, NF dị ala, na uru dị elu.
Uru nke SOA Semiconductor optical amplifier
Uru anya nke SOA na-enye n'ime bandwit bụ nke na-adabereghị na ogologo ogologo nke mgbaàmà anya ihe merenụ.
Tinye ihe dị ugbu a dị ka mgbama mgbapụta gbasiri ike, kama ịgbapụta ngwa anya.
N'ihi nha kọmpat ya, SOA nwere ike jikọta ya na ọtụtụ ngwaọrụ fotonic waveguide na otu mkpụrụ osisi.
4. Ha na-eji otu teknụzụ dị ka lasers diode.
SOA nwere ike na-arụ ọrụ na nkwurịta okwu spectral band nke 1300 nm na 1550 nm, na a wider bandwit (ruo 100 nm).
6. Enwere ike ịhazi ha ma jikọta ha ka ha rụọ ọrụ dị ka preamplifiers na njedebe nke nnata anya.
Enwere ike iji SOA dị ka ọnụ ụzọ mgbagha dị mfe na netwọk anya WDM.

Mmachi nke SOA Semiconductor optical amplifier
SOA nwere ike inye ike ngwa anya ihe ruru iri puku milliwatts (mW), nke zuru oke maka otu ọwa ọrụ na njikọ njikọ fiber optic. Agbanyeghị, sistemụ WDM nwere ike ịchọ ihe ruru mW ike n'otu ọwa.
2. N'ihi nchikota nke ntinye anya fibers n'ime na n'ime ihe ntanetị nke SOA na-ebutekarị nkwụsị mgbaàmà, SOA ga-enyekwu uru ngwa anya iji belata mmetụta nke ọnwụ a na ntinye / mmepụta akụkụ nke mpaghara na-arụ ọrụ.
SOA na-enwe mmetụta nke ukwuu maka ngbanwe nke akara ngosi ntinye anya.
4. Ha na-emepụta ọkwa dị elu nke ụda na mgbasa ozi na-arụ ọrụ karịa eriri amplifiers.
Ọ bụrụ na agbawanye ọtụtụ ọwa anya dị ka achọrọ na ngwa WDM, SOA ga-ebute okwu mkparịta ụka siri ike.
