Ngwa ngwa anya amplifierusoro: Okwu Mmalite nke Semiconductor Optical Amplifier

Ngwa ngwa ngwa nke semiconductor(SOA) bụ amplifier optical nke dabere na mgbasa ozi gain semiconductor. Ọ dị ka ọkpọkọ laser semiconductor nke eriri jikọtara, yana enyo njedebe nke enyo ahụ na-anọchi anya ya na ihe nkiri na-emegide ntụgharị; Enwere ike iji ndị nduzi wave ndị a gbagọrọ agbagọ belata ntụgharị njedebe. A na-ebufe ìhè mgbaàmà site na onye nduzi wave otu-mode semiconductor, yana akụkụ mpụta nke 1-2 μm na ogologo nke ihe dị ka 0.5-2mm. Ụdị waveguide na-adakọ nke ukwuu na mpaghara na-arụ ọrụ (mmụba), nke a na-amịpụta site na ugbu a. Ịgbanye ugbu a na-emepụta njupụta ụfọdụ nke ndị na-ebu ibu na band conduction, na-enye ohere maka mgbanwe anya site na band conduction gaa na band valence. Uru kachasị na-eme na ike photon ntakịrị karịa ike bandgap.

Ngwa ngwa optical semiconductor (SOA) na-eme ka ihe mgbaàmà ìhè nke ihe merenụ dịkwuo elu site na mwepụta ọkụ, usoro ha dịkwa otu ahụ nke laser semiconductor.Ngwa ngwa ngwa SOAbụ naanị laser semiconductor na-enweghị nzaghachi, isi ya bụkwa inweta uru anya site na ịtụgharị ọnụọgụ nke ihe ndị ahụ mgbe a na-agbapụta ihe na-eme ka semiconductor optical amplifier site na optic ma ọ bụ site na eletriki.
Ụdị nkeNgwa ngwa ngwa SOA Semiconductor
Dịka ọrụ SOA na-arụ na sistemụ ndị ahịa si dị, enwere ike kewaa ha n'ime ụdị anọ: serial, booster, switching SOA, na preamplifier.
1. Ntinye ozugbo: uru dị elu, Psat dị mma; NF dị ala na PDG dị ala, nke a na-ejikọkarị na SOA nke na-enweghị polarization ·
2. Mmezi: Psat dị elu, uru dị ala, na-adaberekarị na polarization;
3. Mgbanwe: oke mbibi dị elu na oge mmụba/mbelata ngwa ngwa;
4. Mkpọpụta ihe tupu oge eruo: ọ dị mma maka ogologo oge nnyefe, obere NF, na uru dị elu.
Uru nke SOA Semiconductor optical amplifier
Uru anya nke SOA na-enye n'ime bandwit ahụ anaghị adabere na ogologo ebili mmiri nke mgbaàmà anya ahụ merenụ.
Tinye ọkụ eletrik dị ka ihe mgbaàmà mgbapụta a na-eme ka ọ dịkwuo elu, kama ịgbanye ọkụ eletrik.
N'ihi obere nha ya, enwere ike iji SOA na ọtụtụ ngwaọrụ fotonic waveguide na otu planar substrate.
4. Ha na-eji otu teknụzụ ahụ dịka laser diode.
SOA nwere ike ịrụ ọrụ na eriri nkwukọrịta nke 1300 nm na 1550 nm, yana bandwit sara mbara (ruo 100 nm).
6. Enwere ike ịhazi ha ma jikọta ha ka ha wee jee ozi dị ka ihe nkwado na njedebe nnata optical.
Enwere ike iji SOA dị ka ọnụ ụzọ ezi uche dị mfe na netwọk anya WDM.

Mmachi nke SOA Semiconductor optical amplifier
SOA nwere ike inye ike anya mmepụta nke ruru iri milliwatts (mW), nke zuru oke maka ọrụ otu ọwa na njikọ nkwukọrịta eriri optic. Agbanyeghị, sistemụ WDM nwere ike ịchọ ruo ọtụtụ mW nke ike kwa ọwa.
2. N'ihi njikọ nke eriri anya ntinye n'ime na n'èzí nke ibe SOA agbakwunyere na-akpatakarị mfu mgbaàmà, SOA ga-enye uru anya ọzọ iji belata mmetụta nke mfu a na akụkụ ntinye/mpụta nke mpaghara na-arụ ọrụ.
SOA nwere nnukwu mmetụta maka polarization nke akara ngosi anya ntinye.
4. Ha na-emepụta mkpọtụ dị elu na mgbasa ozi na-arụ ọrụ karịa eriri amplifiers.
Ọ bụrụ na ọtụtụ ọwa anya eme ka ọ dịkwuo mma dịka ọ dị mkpa na ngwa WDM, SOA ga-akpata mkparịta ụka siri ike.
