Kedu ka amplifier optical semiconductor si enweta amplifier?

Kedu ka o si emeamplifier ngwa anya semiconductornweta mmụba?

Mgbe oge nkwukọrịta eriri optical nwere nnukwu ikike, teknụzụ mmụba optical etolitela ngwa ngwa.Ngwa ngwa anyamee ka akara ngosi anya ntinye dịkwuo elu dabere na radieshon kpaliri ma ọ bụ mgbasa ozi kpaliri. Dịka ụkpụrụ ọrụ si dị, enwere ike kewaa amplifiers optical n'ime amplifiers optical semiconductor (SOA) naihe ndị na-eme ka eriri anya dị nro. N'etiti ha,amplifiers ngwa anya semiconductorA na-ejikarị ha eme ihe n'ụzọ sara mbara n'ihe gbasara nkwukọrịta anya site na uru nke eriri uru sara mbara, njikọta dị mma na oke ogologo ebili mmiri sara mbara.

Ebe ọ bụ na ọrụ kachasị mkpa nke amplifiers optical semiconductor bụ amplifier linear, karịsịa iji nweta amplifier, enwere ike iji ya dị ka amplifier ike, amplifier ahịrị na preamplifiers na sistemụ nkwukọrịta. Na njedebe nnyefe, a na-eji amplifier optical semiconductor dị ka amplifier ike iji mee ka ike mmepụta dị na njedebe nnyefe nke sistemụ ahụ dịkwuo elu, nke nwere ike ịbawanye anya relay nke ogwe sistemụ ahụ nke ukwuu. Na ahịrị nnyefe, enwere ike iji amplifier optical semiconductor dị ka amplifier relay linear, ka enwere ike ịgbatị anya relay regenerative nnyefe ọzọ site na mmụba na oke. Na njedebe nnata, enwere ike iji amplifier optical semiconductor dị ka preamplifier, nke nwere ike imeziwanye mmetụta nke onye nnata nke ukwuu. Njirimara saturation uru nke amplifier optical semiconductor ga-eme ka uru kwa bit dịrị na usoro bit gara aga. Enwere ike ịkpọ mmetụta ụkpụrụ dị n'etiti obere ọwa mmetụta cross-gain. Usoro a na-eji nkezi ọnụọgụgụ nke mmetụta cross-gain modulation n'etiti ọtụtụ ọwa ma na-ewebata ebili mmiri dị n'etiti ike na-aga n'ihu na usoro ahụ iji nọgide na-enwe ìhè ahụ, si otú a na-agbakọta uru zuru oke nke amplifier. Mgbe ahụ, mmetụta cross-gain modulation n'etiti ọwa na-ebelata.

Ngwa ngwa optical semiconductor nwere nhazi dị mfe, njikọta dị mfe, ma nwee ike ime ka akara anya nke ogologo ebili dị iche iche dịkwuo elu, a na-ejikwa ha nke ukwuu na njikọta nke ụdị laser dị iche iche. Ugbu a, teknụzụ njikọta laser dabere na ngwa ngwa optical semiconductor ka na-eto eto, mana a ka kwesịrị ime mgbalị n'akụkụ atọ ndị a. Otu bụ ibelata mfu njikọ na eriri optical. Nsogbu bụ isi nke ngwa ngwa optical semiconductor bụ na mfu njikọ na eriri ahụ buru ibu. Iji melite arụmọrụ njikọ, enwere ike itinye oghere na sistemụ njikọ iji belata mfu ntụgharị uche, melite symmetry nke osisi ahụ, ma nweta njikọ arụmọrụ dị elu. Nke abụọ bụ ibelata mfu njikọ nke ngwa ngwa optical semiconductor. Njirimara polarization na-ezo aka na mfu njikọ nke ìhè ihe merenụ. Ọ bụrụ na anaghị ahazi ngwa ngwa optical semiconductor nke ọma, a ga-ebelata bandwit dị irè nke uru ahụ. Nhazi olulu mmiri quantum nwere ike imeziwanye nkwụsi ike nke ngwa ngwa optical semiconductor. O kwere omume ịmụ nhazi olulu quantum dị mfe ma dị elu iji belata mfu njikọ nke ngwa ngwa optical semiconductor. Nke atọ bụ nhazi nke usoro agbakọtara. Ugbu a, njikọta nke amplifiers optical na laser semiconductor dị oke mgbagwoju anya ma sie ike na nhazi teknụzụ, na-ebute nnukwu mfu na nnyefe mgbaàmà optical na mfu ntinye ngwaọrụ, ọnụ ahịa ya dịkwa oke elu. Ya mere, anyị kwesịrị ịgbalị ime ka nhazi nke ngwaọrụ agbakwunyere dịkwuo mma ma melite nkenke nke ngwaọrụ.

Na teknụzụ nkwukọrịta optical, teknụzụ mmụba optical bụ otu n'ime teknụzụ ndị na-akwado ya, teknụzụ mmụba optical semiconductor na-etolite ngwa ngwa. Ugbu a, arụmọrụ nke mmụba optical amplifiers semiconductor emeela nke ọma, ọkachasị na mmepe nke teknụzụ ọhụụ ọgbọ ọhụrụ dịka nhazi nkewa wavelength division multiplexing ma ọ bụ ụdị mgbanwe optical. Site na mmepe nke ụlọ ọrụ ozi, a ga-ewebata teknụzụ mmụba optical nke dabara adaba maka eriri dị iche iche na ngwa dị iche iche, mmepe na nyocha nke teknụzụ ọhụrụ ga-eme ka teknụzụ mmụba optical amplifier semiconductor nọgide na-etolite ma na-aga nke ọma.
