Lub sijhawm kho qhov muag tau yog qhov pom ntawm ib qho ntawm cov neeg muaj peev xwm ntawm cov neeg tau tsim tawm ntawm cov chaw kaw khoom, uas tuaj yeem tsim los ntawm hom-cov khau khiab, Resonators, lossisElectro-Kho Kom Zoo Nkauj ModulatorsCov. Kho qhov muag ua kom zoo nkauj combs tsim los ntawmElectro-Optic ModulatorsMuaj cov yam ntxwv ntawm kev rov ua dua siab zaus, sab hauv kev siv dag zog thiab muaj zog, thiab lwm yam kev paub ntau thiab ntau cov kws tshawb fawb 'txaus siab rau xyoo tsis ntev los no.
Tsis ntev los no, Alexandre Parriaux thiab lwm tus los ntawm University of Burgendi nyob rau hauv Fabkis tshaj tawm kev tshawb fawb tshiab thiab kev thov Optical zaus Combs tsim los ntawmElectro-Kho Kom Zoo: Nws suav nrog kev qhia ntawm kev siv hluav taws xob hloov pauv, cov qauv thiab cov yam ntxwv ntawm kev siv kho dua tshiab sib xyaw ua ke los ntawmElectro-Optic Modulator, thiab thaum kawg nkag rau daim ntawv thov cov xwm txheej ntawmElectro-Optic ModulatorKev siv zog ua kom zoo zuag ntsis sib xyaw ua ke, suav nrog daim ntawv thov ntawm precision spectrum, thiab kev tawm tsam lub hauv paus ntsiab lus qab cov ntawv thov sib txawv. Thaum kawg, tus kws sau muab lub zeem muag ntawm electro-optic modulator optical zaus comic technology.

Nws yog 60 xyoo dhau los lub hlis uas Dr. Maiman tau tsim cov ruby laser. Plaub xyoos tom qab, hargrove, fock thiab pollack ntawm tswb-neers-tooling ua tiav hauv lub sijhawm lub sijhawm ua haujlwm nyob rau hauv lub sijhawm lub sijhawm yog sawv cev raws li cov mem tes tso, Nyob rau hauv qhov zaus sau yog cov kab sib txawv thiab cov sib npaug luv, zoo sib xws rau peb txhua hnub ntawm cov combs, yog li peb hu rau qhov kev siv hluav taws xob txhua hnub ". Raug xa mus rau raws li "optic zaus zuag".
Vim tias cov ntawv thov zoo ntawm Optical Comb, lub Nobel nqi zog hauv Hansch thiab Hall, leej twg ua rau kev txhim kho kho qhov muag tau mus txog theem tshiab. Vim tias cov ntawv thov sib txawv muaj cov sib txawv ntawm cov khoom siv kho mob, xws li cov hlua khi, cov qauv siv micro cov xov tooj thiab hluav taws xob modulator.

Duab Tau Los Ntawm: Electro-Optic zaus combs
Txij thaum pom pom ntawm cov khoom siv kho qhov muag ntau dua, feem ntau ntawm cov zaus muaj muag ntau dua tau ua rau cov roj hmab-xauv laseed. Nyob rau hauv hom-muab cov hlua khi, cov kab noj hniav nrog lub sijhawm sib tw ntawm kev sib tw sib tw ntawm Laser, uas feem ntau tuaj yeem yog Megahertz (MHz) mus rau Gegahertz ( GHz).
Lub sijhawm kho qhov muag tau tsim los ntawm cov micro-resonator yog txiav txim siab ntawm cov micro-kab noj hniav yog feem ntau tsawg dua 1 hli, cov zaus saib xyuas zuag nplooj siab los ntawm cov micro-kab noj hniav feem ntau yog feem ntau 10 gigahertz rau 1 terahertz. Muaj peb hom microcavities, microlotubules, microspheres thiab microrings. Siv cov kev cuam tshuam tsis zoo hauv cov khoom siv kho qhov muag, xws li brilleyin scationing lossis plaub-yoj sib xyaw, sib xyaw nrog cov microcavities, ua ke nrog cov microcavities, ua ke nrog cov me me hauv lub ncov ntawm nanometers ntau yam tuaj yeem tsim tawm. Tsis tas li ntawd, kev ntsuas qhov muag tau combs kuj tseem tuaj yeem tsim los ntawm kev siv qee cov acousto-optic modulators.
