Yini i-electro-optic modulator ama-frequer frequency comm? Ingxenye eyodwa

I-Optical Frequency Calk iyinhlangano eyakhiwe ngochungechunge lwezakhi zezakhi zemvamisa ezihlelwe ngokulinganayo ku-spectrum, ezingakhiqizwa ngama-lasers akhiyiwe amamodi, ama-resonators, nomaI-Electro-Optical Modulators. I-Optical Frequency Coms eyenziwe nguI-Electro-Optic ModulatorsYiba nezimpawu zemvamisa ephezulu yokuphindaphinda, ukuhlukaniswa kwangaphakathi namandla aphezulu, njll.

Muva nje, u-Alexandre Parriaux nabanye abavela e-University of Burgendi eFrance bashicilela iphepha lokubuyekezwa ejele ku-Optics nase-Photonics, ehlele ngokuhlelekile inqubekela phambili yokucwaninga kwakamuva okukhiqizwe yiUkushintshwa kwe-Electro-Optical: Kubandakanya ukwethulwa kwe-Optical Frequency Calm, indlela nezimpawu ze-Optical Frequency COMBED ezikhiqizwe nguI-Electro-Optic Modulator, futhi ekugcineni uvumelanisa izimo zohlelo lokusebenza zeI-Electro-Optic ModulatorI-Optical Frequency comment ngokuningiliziwe, kufaka phakathi ukusetshenziswa kwe-Precision Spectrum, ukuphazamiseka kwensimbi okuphindwe kabili, ukulinganisa insimbi yokulinganisa, bese kuxoxa ngesimiso ngemuva kwezicelo ezahlukahlukene. Ekugcineni, umbhali unikeza ithemba le-Electro-Optic Modulator Optical Frequency Construction Const Technology.

01 ingemuva

Kwakuyiminyaka engama-60 edlule kule nyanga uDkt Maiman wasungula i-saser yokuqala ye-ruby. Ngemuva kweminyaka emine, Harglove, Fock kanye nePolack of Bell Laseratories e-United States kwakuwukuqala kwe-Mode-Neon Kubhekiswe kuyo njenge- "fakency structency comb".

Ngenxa yethemba lesicelo esihle se-Optical Com, umklomelo kaNobel ku-physics ngo-2005 wanikezwa uHansch naseHholo, owenza umsebenzi wokuphayona ebukhwini be-Optical Work, kusukela ngaleso sikhathi, ukuthuthukiswa kwe-Optical Hork kufinyelele esigabeni esisha. Ngoba izinhlelo zokusebenza ezahlukahlukene zinezidingo ezihlukile zokuhlanza okubonakalayo, njengamandla, ukuhlukaniswa komugqa kanye ne-wavelth ephakathi nendawo, njengama-lases avaliwe, ama-micro-resonical modulator.

Umthombo Wezithombe: Ama-Electro-Optic Frequency Combs

Kusukela ukutholwa kwama-optical frequency affectuency combs, iningi le-Optical Frequency Combs likhiqizwe kusetshenziswa ama-lasers akhiywe ngemodi. Ku-lasers ekhiyiwe yemodi, umgodi onesikhashana sokujikeleza kwe-vened usetshenziselwa ukulungisa ubudlelwano besigaba phakathi kwezindlela ezinde, ukuze unqume inani lokuphindaphindeka kwe-laser, elingaba yi-Gigahertz (i-GHz).

I-Optical Frequency COMCED ekhiqizwe ngumshayeli we-micro-resonator isuselwa emiphumeleni engeyona eye-cavity, futhi isikhathi sohambo oluyindilinga sinqunywa ngobude be-micro-cavity, ngoba ubude be-micro-cavity ngokuvamile bungaphansi kwe-micro-cavity ngokuvamile i-10 Gigahertz kuya ku-1 terahertz. Kunezinhlobo ezintathu ezivamile zezinto ezikwi-microcavities, ama-microtubule, ama-microslos kanye nama-microrings. Kusetshenziswa imiphumela engabonakali emicu ye-Optical Fibers, njengokusakazeka kwe-brillouin noma ukuxubana kwama-wave, kuhlanganiswe nezinto eziyi-microcavitis, ama-optical frequency affectuency emashumini amabanga amabanga ama-nanometers angakhiqizwa. Ngaphezu kwalokho, ama-optical frequency afrifathi angenziwa futhi ngokusebenzisa amanye amamodu we-acousto-optic.
