Dab tsi yog "super radiant"lub teeb ci"? Koj paub ntau npaum li cas txog nws? Kuv vam tias koj tuaj yeem saib zoo txog kev paub txog photoelectric micro uas coj los rau koj!"
Lub teeb ci ntsa iab heev (tseem hu uaASE lub teeb ci) yog lub teeb ci dav dav (lub teeb dawb) raws li superradiation. (Nws feem ntau hu ua qhov chaw superluminous, uas yog raws li qhov xwm txheej sib txawv hu ua superfluorescence.) Feem ntau, lub teeb ci superradiant muaj cov khoom siv laser uas ci lub teeb tom qab kev txhawb siab thiab tom qab ntawd ua kom nws loj dua kom tso tawm lub teeb.
Cov chaw muaj zog superradiant muaj qhov sib xws ntawm lub sijhawm qis heev vim lawv cov kab hluav taws xob loj (piv rau lasers). Qhov no txo qhov ua tau ntawm cov teeb pom kev zoo, uas feem ntau pom hauv cov teeb laser. Txawm li cas los xij, nws qhov sib xws ntawm qhov chaw siab heev, thiab lub teeb tso zis ntawm lub teeb ultra-radiant tuaj yeem tsom mus rau qhov zoo (zoo ib yam li lub teeb laser), yog li lub zog teeb pom kev zoo dua li lub teeb incandescent.
Nws yog ib qho khoom siv zoo heev rau kev siv lub teeb pom kev zoo sib xws (OpticalCoherenceTomography, OCT), kev tshuaj xyuas cov yam ntxwv ntawm cov khoom siv () hauv kev sib txuas lus fiber ntau, gyro thiab optical fiber sensor. Saib superemitting diodes rau cov ntawv thov ntxaws ntxiv.
Ib qho ntawm cov teeb pom kev zoo tshaj plaws rau ultra radiation diode (Superluminescent Diodes)SLD laser) thiab cov khoom siv fiber ntau optical. Cov khoom siv teeb pom kev zoo uas siv fiber ntau muaj zog tso zis ntau dua, thaum SLD me dua thiab pheej yig dua. Ob qho tib si muaj cov kab hluav taws xob tsawg kawg yog ob peb nanometers thiab kaum tawm nanometers, thiab qee zaum txawm tias loj dua 100 nanometers.
Rau txhua qhov chaw teeb pom kev zoo ASE, cov lus teb optical (piv txwv li, kev cuam tshuam los ntawm cov chaw nres nkoj fiber) yuav tsum tau ua tib zoo suppressed, yog li nws tsim cov nyhuv parasitic laser. Raucov khoom siv fiber optic, Rayleigh scattering sab hauv cov fiber ntau optical yuav cuam tshuam rau qhov ntsuas kev ua tau zoo kawg.
Daim Duab 1: Lub spectrum ASE tsim los ntawm lub fiber amplifier yog xam ua ib qho nkhaus ntawm ntau lub zog twj tso kua mis. Thaum lub zog nce ntxiv, lub spectrum txav mus rau qhov luv dua wavelength (qhov nce ntxiv sai sai) thiab kab spectral nqaim. Kev hloov pauv ntawm qhov ntev yog qhov ib txwm muaj rau cov xov xwm nce qib quasi-peb-qib, thaum kab nqaim tshwm sim hauv yuav luag txhua qhov chaw superradiant.
