Chii chinonzi "chinopenya zvikuru"chiedza chinobva"? Unoziva zvakawanda sei nezvazvo? Ndinovimba unogona kuona ruzivo rwema microelectric micro rwunounzwa kwauri!"
Chiedza chinopenya zvikuru (chinozivikanwawo seASE chiedza chinobva) itsime remwenje rebroadband (chiedza chichena) rakavakirwa pamwaranzi yepamusoro. (Inowanzonzi chitubu chine chiedza chakawanda, icho chakavakirwa pane chimwe chinhu chinonzi superfluorescence.) Kazhinji, chitubu chechiedza chakanyanya kupenya chine laser gain medium inoburitsa chiedza mushure mekufemerwa uye yobva yachiwedzera kuti ibudise chiedza.
Manyuko emwenje anopenya zvikuru ane kubatana kwakaderera kwenguva pfupi nekuda kwehuwandu hwemwaranzi hwakakura (zvichienzaniswa nemalaser). Izvi zvinoderedza zvikuru mukana wekuti pave nenzvimbo dzechiedza, dzinowanzoonekwa mumwaranzi unopenya. Zvisinei, kubatana kwaro munzvimbo kwakakwira zvikuru, uye chiedza chinobuda kubva kuchiedza chinopenya zvikuru chinogona kunge chakanyatsojeka (kufanana nemwaranzi unopenya), saka kusimba kwechiedza kwakakwira zvikuru kupfuura kwemwenje unopenya.
Inyanzvi yekuongorora chiedza inoshanda zvakanaka ne optics coherent light source tomography (OpticalCoherenceTomography, OCT), kuongorora hunhu hwechishandiso () mu optical fiber communication, gyro uye optical fiber sensor. Ona superemitting diodes kuti uwane mamwe mashandisirwo akazara.
Imwe yenzvimbo huru dzechiedza chemwaranzi ye ultra radiation diode (Superluminescent Diodes)SLD laser) uye optical fiber amplifier. Matangi emwenje akavakirwa pafiber ane simba guru rekuburitsa simba, nepo SLD iri diki uye isingadhuri zvakanyanya. Ose ane bandwidth yemwaranzi inosvika nanometer shoma uye makumi e nanometer, uye dzimwe nguva inotopfuura 100 nanometers.
Kune ese masource emwenje eASE ane gain yakawanda, mhinduro yemaziso (semuenzaniso, kuratidzwa kubva kuma fiber ports) inofanirwa kudziviswa nokungwarira, saka inogadzira parasitic laser effect.zvishandiso zvefiber zve optical, Kupararira kweRayleigh mukati me optical fiber kuchakanganisa chiyero chekupedzisira chekushanda.
Mufananidzo 1: ASE spectrum inogadzirwa nefiber amplifier inoverengwa se curve pamasimba akasiyana epombi. Sezvo simba richiwedzera, spectrum inofamba ichienda kune wavelength pfupi (gain inowedzera nekukurumidza) uye spectral line Inonamira. Kuchinja kwewavelength kwakajairika kune quasi-three-level gain media, nepo mutsetse unotetepa unoitika munzvimbo dzinenge dzese dzine chiedza chakanyanya.
