Chii chinonzi "kupenya kwakanyanyalight source“? Zvakawanda sei zvaunoziva nezvazvo? Ndinovimba iwe unogona kutarisa zvakanaka iyo photoelectric micro ruzivo yakaunzwa kwauri!
Superradiant light source (inozivikanwawo seASE mwenje sosi) ndeye Broadband light source (white light source) yakavakirwa pa superradiation. (Inowanzodaidzwa zvisirizvo kuti superluminous sosi, iyo yakavakirwa pane chimwe chiitiko chinonzi superfluorescence.) Kazhinji, superradiant light source ine laser gain medium iyo inopenya mwenje mushure mekunakidzwa uye yobva yakudza kuti ibudise chiedza.
Superradiant masosi ane yakaderera kwenguva yekubatana nekuda kweiyo yakakura radiation bandwidth (ichienzaniswa ne lasers). Izvi zvinoderedza zvakanyanya mukana wemavara emwenje, ayo anowanzo onekwa mumalaser matanda. Nekudaro, kurongeka kwayo kwenzvimbo kwakakwira zvakanyanya, uye mwenje unobuda weiyo Ultra-inopenya mwenje sosi inogona kunyatsotariswa (yakafanana nelaser beam), saka kusimba kwemwenje kwakakwira zvakanyanya kupfuura iyo yemwenje incandescent.
Iyo yakanyatsokodzera optics inobatana light source tomography (OpticalCoherenceTomography, OCT), mudziyo hunhu kuongorora () mune optical fiber kutaurirana, gyro uye optical fiber sensor. Ona superemitting diodes kuti uwane mamwe maapplication.
Imwe yeakanyanya mwenje mwenje sosi ye Ultra radiation diode (Superluminescent DiodesSLD laser) uye optical fiber amplifier. Fibre-yakavakirwa mwenje masosi ane yakakwira kubuda simba, nepo SLD idiki uye isingadhure. Ose ane radiation bandwidths angangoita mashoma nanometers uye makumi ema nanometers, uye dzimwe nguva anotopfuura zana nanometers.
Kune ese makuru-anowana ASE magetsi masosi, optical mhinduro (semuenzaniso, kuratidzira kubva kune fiber ports) inoda kudzvanywa, saka inogadzira parasitic laser athari. Foroptical fiber zvishandiso, Rayleigh kuparadzira mukati me optical fiber ichakanganisa yekupedzisira performance index.
Mufananidzo 1: Iyo ASE spectrum inogadzirwa nefiber amplifier inoverengerwa securve pamasimba akasiyana epombi. Sezvo simba richiwedzera, spectrum inofamba ichienda kupfupi wevelength (kuwana kunowedzera nekukurumidza) uye spectral line Narrows. Kuchinja kwewavelength kwakajairika kune quasi-matatu-nhanho kuwana midhiya, nepo kutetepa kwemutsara kunoitika munenge mune ese superradiant masosi.
