Kodi “wowala kwambirigwero lowala“?Kodi mumadziwa bwanji za izo?Ndikukhulupirira kuti mutha kuyang'ana bwino chidziwitso chaching'ono cha photoelectric chomwe chabweretsedwa kwa inu!
Superradiant light source (yomwe imadziwikanso kutiGwero la kuwala kwa ASE) ndi gwero la kuwala kwa burodibandi (gwero lounikira loyera) lozikidwa pa ma radiation.(Nthawi zambiri amatchulidwa molakwika kuti ndi gwero lapamwamba kwambiri, lomwe limachokera ku chinthu china chotchedwa superfluorescence.) Kawirikawiri, kuwala kwapamwamba kwambiri kumakhala ndi laser gain medium yomwe imatulutsa kuwala pambuyo pa chisangalalo ndiyeno imakulitsa kuti itulutse kuwala.
Magwero a superradiant amakhala otsika kwambiri pakanthawi kochepa chifukwa cha bandwidth yawo yayikulu (poyerekeza ndi ma lasers).Izi zimachepetsa kwambiri kuthekera kwa mawanga opepuka, omwe nthawi zambiri amawonekera mu matabwa a laser.Komabe, kugwirizana kwake kwa malo ndikokwera kwambiri, ndipo kuwala kotulutsa kuwala kwa ultra-radiant kumatha kuyang'ana bwino (mofanana ndi kuwala kwa laser), kotero kuwala kwake kumakhala kwakukulu kwambiri kuposa kwa nyali ya incandescent.
Ndikofunikira kwambiri kwa optics coherent light source tomography (OpticalCoherenceTomography, OCT), kusanthula mawonekedwe a chipangizo () mu optical fiber communication, gyro ndi optical fiber sensor.Onani ma diode apamwamba kuti mumve zambiri.
Chimodzi mwazinthu zazikulu zowunikira ma radiation a ultra radiation diode (Superluminescent DiodesSLD laser) ndi optical fiber amplifier.Magetsi opangidwa ndi fiber amakhala ndi mphamvu zotulutsa zambiri, pomwe SLD ndi yaying'ono komanso yotsika mtengo.Onsewa ali ndi ma bandwidths osachepera ma nanometers ochepa ndi makumi a nanometers, ndipo nthawi zina amaposa ma nanometer 100.
Pazowunikira zonse za ASE zopeza bwino kwambiri, mayankho owoneka bwino (mwachitsanzo, kuwunikira kuchokera kumadoko a fiber) amayenera kuponderezedwa mosamala, motero zimapangitsa kuti pakhale parasitic laser effect.Zazida za optical fiber, Rayleigh kufalikira mkati mwa kuwala kwa fiber kudzakhudza ndondomeko yomaliza ya ntchito.
Chithunzi 1: Mawonekedwe a ASE opangidwa ndi fiber amplifier amawerengedwa ngati ma curve pa mphamvu zosiyanasiyana zapampu.Pamene mphamvu ikuwonjezeka, mawonekedwewo amapita kufupikitsa wavelength (kupindula kumawonjezeka mofulumira) ndipo mzere wa spectral umachepa.Kusintha kwa kutalika kwa mafunde kumakhala kwachilendo kwa ma quasi-atatu-level gain media, pomwe kuchepa kwa mzere kumachitika pafupifupi magwero onse opitilira muyeso.
