Kodi asemiconductor kuwala amplifier
Semiconductor Optical amplifier ndi mtundu wa amplifier opangira omwe amagwiritsa ntchito semiconductor kupeza sing'anga. Ndizofanana ndi laser diode, momwe galasi lomwe lili kumapeto kwenikweni limasinthidwa ndi zokutira zowoneka bwino. Kuwala kwa chizindikiro kumafalikira kudzera mu semiconductor single-mode waveguide. Kukula kozungulira kwa waveguide ndi 1-2 micrometer ndipo kutalika kwake kuli pa dongosolo la 0.5-2mm. Mawonekedwe a waveguide ali ndi kuphatikizika kwakukulu ndi dera logwira ntchito (kukulitsa), lomwe limapopedwa ndi pano. Jekiseniyo imapanga chonyamulira chamtundu wina mu bandi ya conduction, zomwe zimalola kusintha kwa mawonekedwe a bandi ya conduction kupita ku gulu la valence. Kupindula kwakukulu kumachitika pamene mphamvu ya photon imakhala yaikulu pang'ono kuposa mphamvu ya bandgap. SOA Optical amplifier imagwiritsidwa ntchito pamakina olumikizirana ma telecommunication ngati ma pigtails, okhala ndi kutalika kogwira ntchito mozungulira 1300nm kapena 1500nm, kupereka pafupifupi 30dB phindu.
TheSOA semiconductor Optical amplifierndi chipangizo cholumikizira cha PN chokhala ndi chitsime cha strain quantum. Kukondera kwakunja kwakunja kumasinthiratu kuchuluka kwa tinthu tating'onoting'ono ta dielectric. Pambuyo polowera kunja kwa kuwala kwachisangalalo, ma radiation olimbikitsa amapangidwa, kukwaniritsa kukweza kwa zizindikiro za kuwala. Njira zitatu zomwe zili pamwambazi zotumizira mphamvu zilipoSOA Optical amplifier. Kukulitsa kwa ma siginecha owoneka kumatengera kutulutsa kolimbikitsa. Mayamwidwe okondowetsedwa ndi njira zokometsera zotulutsa zimakhalapo nthawi imodzi. Mayamwidwe olimbikitsa a pampu angagwiritsidwe ntchito kufulumizitsa kuchira kwa zonyamulira, ndipo nthawi yomweyo, pampu yamagetsi imatha kutumiza ma elekitironi kumlingo wapamwamba kwambiri (gulu la conduction). Pamene ma radiation ochitika mwadzidzidzi achulukidwa, amapangika phokoso lokhazikika lokhazikika. SOA Optical amplifier imatengera tchipisi ta semiconductor.
Ma semiconductor chips amapangidwa ndi ma semiconductors apawiri, monga GaAs/AlGaAs, InP/AlGaAs, InP/InGaAsP ndi InP/InAlGaAs, etc. Izinso ndi zida zopangira ma semiconductor lasers. Mapangidwe a waveguide a SOA ndi ofanana kapena ofanana ndi a lasers. Kusiyanaku kuli chifukwa ma lasers amafunikira kupanga kabowo kakang'ono kozungulira kuzungulira kwapakati kuti apange ndikusunga kusinthasintha kwa chizindikiro cha kuwala. Chizindikiro cha kuwala chidzakulitsidwa kangapo m'kati mwake chisanatulutsidwe. MuSOA amplifier(zomwe tikukambirana pano ndizochepa zopangira mafunde oyendayenda omwe amagwiritsidwa ntchito nthawi zambiri), kuwala kumangofunika kudutsa njira yowonjezera kamodzi, ndipo kuwonetsera kumbuyo kumakhala kochepa. Mapangidwe a amplifier a SOA ali ndi madera atatu: Area P, Area I (yosanjikiza kapena node), ndi Area N. Chigawo chogwira ntchito nthawi zambiri chimapangidwa ndi quantum Wells, zomwe zingapangitse kusintha kwa photoelectric kusinthika ndikuchepetsa mphamvu yapano.
Chithunzi 1 Fiber laser yokhala ndi SOA yophatikizika yopanga ma pulses optical
Ikugwiritsidwa ntchito pa kusamutsa tchanelo
Ma SOA nthawi zambiri samangogwiritsidwa ntchito pakukulitsa: amathanso kugwiritsidwa ntchito polumikizana ndi ma fiber optical, ntchito zochokera kuzinthu zopanda malire monga kukhutitsidwa kwa machulukitsidwe kapena polarization yapakati, yomwe imagwiritsa ntchito kusiyanasiyana kwa chonyamulira mu SOA optical amplifier kuti apeze ma indices a refractive. Zotsatirazi zingagwiritsidwe ntchito pa kusamutsidwa kwa njira (kutembenuka kwa kutalika kwa mawonekedwe), kutembenuka kwa mawonekedwe osinthika, kubwezeretsa mawotchi, kusinthika kwa chizindikiro ndi kuzindikira kwachitsanzo, ndi zina zotero.
Ndi kupita patsogolo kwa optoelectronic Integrated circuit teknoloji ndi kuchepetsa ndalama zopangira, minda yogwiritsira ntchito SOA semiconductor optical amplifier monga ma amplifiers oyambira, zida zogwirira ntchito zogwirira ntchito ndi zigawo za subsystem zidzapitiriza kukula.
