Cov koob yees duab amplifier: Kev Taw Qhia rau Semiconductor Optical Amplifier

Lub tshuab ua kom pom kev zooseries: Kev Taw Qhia rau Semiconductor Optical Amplifier

Lub tshuab hluav taws xob semiconductor optical amplifier(SOA) yog ib lub amplifier optical raws li semiconductor gain media. Nws zoo li lub fiber txuas semiconductor laser tube, nrog rau daim iav kawg hloov los ntawm ib zaj duab xis tiv thaiv kev cuam tshuam; Tilted waveguides tuaj yeem siv los txo qhov kawg reflectivity. Lub teeb liab feem ntau yog kis tau los ntawm semiconductor ib hom waveguide, nrog rau qhov ntev ntawm 1-2 μ m thiab ntev li ntawm 0.5-2 hli. Lub waveguide hom sib tshooj nrog thaj chaw nquag (amplification), uas yog pumped los ntawm tam sim no. Kev txhaj tshuaj tam sim no tsim ib qho kev ceev ntawm cov neeg nqa khoom hauv conduction band, tso cai rau kev hloov pauv optical los ntawm conduction band mus rau valence band. Qhov siab tshaj plaws tshwm sim ntawm photon energies me ntsis saum toj no lub zog bandgap.

Txoj cai ua haujlwm ntawm semiconductor optical amplifier
Cov khoom siv hluav taws xob semiconductor optical amplifiers (SOA) ua kom cov teeb liab tshwm sim loj dua los ntawm kev tso tawm, thiab lawv cov txheej txheem zoo ib yam li cov lasers semiconductor.SOA optical amplifiertsuas yog ib lub semiconductor laser uas tsis muaj kev tawm tswv yim, thiab nws lub hauv paus yog kom tau txais qhov nce optical los ntawm kev thim rov qab tus lej ntawm cov khoom me me thaum lub semiconductor optical amplifier raug optically lossis electrically pumped.
Hom ntawmSOA Semiconductor optical amplifier
Raws li lub luag haujlwm uas SOA ua si hauv cov neeg siv khoom, lawv tuaj yeem muab faib ua plaub pawg: serial, booster, switching SOA, thiab preamplifier.
1. Kev ntxig ncaj qha: qhov nce siab dua, Psat nruab nrab; NF qis dua thiab PDG qis dua, feem ntau cuam tshuam nrog polarization ywj pheej SOA·
2. Enhancer: Psat siab dua, qhov nce qis dua, feem ntau nyob ntawm polarization;
3. Hloov: qhov piv txwv ploj mus siab dua thiab lub sijhawm nce / poob sai dua;
4. Pre amplifier: tsim nyog rau kev sib kis ntev dua, NF qis dua, thiab nce siab dua.
Cov txiaj ntsig ntawm SOA Semiconductor optical amplifier
Qhov nce qib optical uas muab los ntawm SOA hauv bandwidth yog qhov ywj pheej ntawm qhov wavelength ntawm qhov teeb meem optical teeb liab.
Txhaj tshuaj tam sim no ua lub teeb liab twj tso kua mis, es tsis yog lub twj tso kua mis pom.
Vim nws qhov me me, SOA tuaj yeem koom ua ke nrog ntau lub waveguide photonic li ntawm ib qho planar substrate.
4. Lawv siv tib lub thev naus laus zis li diode lasers.
SOA tuaj yeem ua haujlwm hauv cov kev sib txuas lus spectral ntawm 1300 nm thiab 1550 nm, nrog rau bandwidth dav dua (txog li 100 nm).
6. Lawv tuaj yeem teeb tsa thiab koom ua ke los ua cov preamplifiers ntawm qhov kawg ntawm lub optical receiver.
SOA siv tau ua lub rooj vag logic yooj yim hauv WDM optical networks.

Cov kev txwv ntawm SOA Semiconductor optical amplifier
SOA tuaj yeem muab cov zis hluav taws xob optical txog li kaum tawm milliwatts (mW), uas feem ntau txaus rau kev ua haujlwm ib txoj hauv kev hauv kev sib txuas lus fiber optic. Txawm li cas los xij, WDM systems yuav xav tau txog li ntau mW ntawm lub zog ib txoj hauv kev.
2. Vim yog qhov kev sib txuas ntawm cov fibers optical nkag mus rau hauv thiab tawm ntawm SOA integrated chips feem ntau ua rau lub teeb liab poob, SOA yuav tsum muab cov txiaj ntsig optical ntxiv kom txo qhov cuam tshuam ntawm qhov poob no rau ntawm cov tswv yim / tso zis ntawm thaj chaw nquag.
SOA muaj kev nkag siab zoo rau qhov polarization ntawm cov teeb liab tawm tswv yim.
4. Lawv tsim cov suab nrov dua hauv cov xov xwm nquag dua li cov amplifiers fiber.
Yog tias ntau txoj kev kho qhov muag tau raug nthuav dav raws li qhov xav tau hauv WDM daim ntawv thov, SOA yuav ua rau muaj kev sib txuas lus hnyav.
