Ib qho sib xyaw ua ke ntawm cov zaus sib txawv yog ib qho spectrum uas muaj cov khoom sib txawv ntawm cov zaus sib txawv ntawm cov spectrum, uas tuaj yeem tsim los ntawm cov lasers hom-xauv, resonators, lossiscov khoom siv hluav taws xob kho qhov muagCov zaus kho qhov muag sib xyaw ua ke tsim los ntawmcov khoom siv hluav taws xob-optic modulatorsmuaj cov yam ntxwv ntawm kev rov ua dua zaus, kev sib xyaw sab hauv thiab lub zog siab, thiab lwm yam, uas tau siv dav hauv kev ntsuas cov cuab yeej, spectroscopy, lossis kev kawm txog lub cev, thiab tau nyiam ntau tus kws tshawb fawb ntau dua nyob rau xyoo tas los no.
Tsis ntev los no, Alexandre Parriaux thiab lwm tus los ntawm University of Burgendi hauv Fabkis tau luam tawm ib daim ntawv tshuaj xyuas hauv phau ntawv xov xwm Advances in Optics thiab Photonics, qhia txog kev tshawb fawb tshiab thiab kev siv cov khoom siv zaus optical uas tsim los ntawmkev hloov kho hluav taws xob: Nws suav nrog kev qhia txog kev siv lub zog zaus kho qhov muag, txoj kev thiab cov yam ntxwv ntawm kev siv lub zog zaus kho qhov muag uas tsim los ntawmelectro-optic modulator, thiab thaum kawg teev cov xwm txheej ntawm daim ntawv thovelectro-optic modulatorqhia txog kev siv optical frequency comb kom ntxaws, suav nrog kev siv precision spectrum, double optical comb interference, instrument calibration thiab arbitrary waveform generation, thiab tham txog lub hauv paus ntsiab lus ntawm ntau yam kev siv. Thaum kawg, tus sau tau muab lub cib fim ntawm electro-optic modulator optical frequency comb technology.

Lub hlis no yog 60 xyoo dhau los uas Dr. Maiman tau tsim thawj lub ruby laser. Plaub xyoos tom qab, Hargrove, Fock thiab Pollack ntawm Bell Laboratories hauv Tebchaws Meskas yog thawj tus tshaj tawm txog kev ua haujlwm hom-locking tiav hauv helium-neon lasers, lub hom-locking laser spectrum hauv lub sijhawm sau yog sawv cev ua lub zog pulse, hauv lub zaus sau yog ib qho ntawm cov kab luv luv thiab sib npaug, zoo ib yam li peb siv txhua hnub ntawm combs, yog li peb hu cov spectrum no "optical frequency comb". Hu ua "optic frequency comb".
Vim yog qhov kev siv tau zoo ntawm cov zuag hluav taws xob, xyoo 2005 tau muab rau Hansch thiab Hall, uas tau ua haujlwm thawj zaug ntawm cov thev naus laus zis zuag hluav taws xob, txij thaum ntawd los, kev txhim kho ntawm cov zuag hluav taws xob tau mus txog theem tshiab. Vim tias cov ntawv thov sib txawv muaj cov kev xav tau sib txawv rau cov zuag hluav taws xob, xws li lub zog, qhov sib nrug ntawm kab thiab qhov ntev ntawm lub hauv paus, qhov no tau ua rau xav tau siv ntau txoj kev sim sib txawv los tsim cov zuag hluav taws xob, xws li cov lasers hom xauv, micro-resonators thiab electro-optical modulator.
DUAB 1 Lub sijhawm sau spectrum thiab zaus sau spectrum ntawm optical frequency comb
Duab los ntawm: Electro-optic zaus combs
Txij li thaum pom cov teeb pom kev zoo ntawm cov teeb pom kev zoo, feem ntau cov teeb pom kev zoo tau tsim los ntawm kev siv cov lasers hom xauv. Hauv cov lasers hom xauv, lub qhov nrog lub sijhawm ncig ntawm τ yog siv los kho qhov kev sib raug zoo ntawm cov hom ntev, yog li txiav txim siab qhov rov ua dua ntawm lub laser, uas feem ntau tuaj yeem yog los ntawm megahertz (MHz) rau gigahertz (GHz).
Lub zog zaus optical comb uas tsim los ntawm micro-resonator yog raws li cov teebmeem nonlinear, thiab lub sijhawm ncig-mus yog txiav txim siab los ntawm qhov ntev ntawm micro-cavity, vim tias qhov ntev ntawm micro-cavity feem ntau tsawg dua 1 hli, lub zog zaus optical comb uas tsim los ntawm micro-cavity feem ntau yog 10 gigahertz rau 1 terahertz. Muaj peb hom microcavities, microtubules, microspheres thiab microrings. Siv cov teebmeem nonlinear hauv cov fibers optical, xws li Brillouin scattering lossis plaub-yoj sib xyaw, ua ke nrog microcavities, optical frequency combs hauv kaum ntawm nanometers ntau yam tuaj yeem tsim tau. Tsis tas li ntawd, optical frequency combs kuj tuaj yeem tsim tau los ntawm kev siv qee cov acousto-optic modulators.
