02i-electro-optic modulatorkwayeukuguquguquka kwe-electro-opticikama ye-frequency ebonakalayo
Isiphumo se-electro-optical sibhekisa kwisiphumo sokuba isalathisi sokukhanyela sezinto ezisetyenziswayo sitshintshe xa kusetyenziswa intsimi yombane. Kukho iintlobo ezimbini eziphambili zesiphumo se-electro-optical, enye yisiphumo se-electro-optical esiphambili, esaziwa ngokuba yi-Pokels effect, esibhekisa kutshintsho oluthe ngqo lwesalathisi sokukhanyela kwezinto ezisetyenziswayo kunye nentsimi yombane esetyenziswayo. Enye yisiphumo sesibini se-electro-optical, esaziwa ngokuba yi-Kerr effect, apho utshintsho kwisalathisi sokukhanyela kwezinto luhambelana nesikwere sentsimi yombane. Uninzi lwee-modulators ze-electro-optical zisekelwe kwisiphumo se-Pokels. Sisebenzisa i-modulator ye-electro-optic, sinokuguqula isigaba sokukhanya kwesiganeko, kwaye ngokusekelwe kwi-modulation yesigaba, ngokuguqulwa okuthile, sinokuguqula nobunzulu okanye i-polarization yokukhanya.
Kukho izakhiwo ezahlukeneyo zeklasikhi, njengoko kubonisiwe kuMfanekiso 2. (a), (b) kunye no-(c) zonke ziizakhiwo ze-modulator enye enesakhiwo esilula, kodwa ububanzi bomgca we-optical frequency comb evelisiweyo bunqunyelwe yi-bandwidth ye-electro-optical. Ukuba i-optical frequency comb ene-frequency ephezulu yokuphindaphinda iyadingeka, kufuneka ii-modulators ezimbini okanye ngaphezulu kwi-cascade, njengoko kubonisiwe kuMfanekiso 2(d)(e). Uhlobo lokugqibela lwesakhiwo oluvelisa i-optical frequency comb lubizwa ngokuba yi-electro-optical resonator, eyi-electro-optical modulator ebekwe kwi-resonator, okanye i-resonator ngokwayo inokuvelisa i-electro-optical effect, njengoko kubonisiwe kuMfanekiso 3.

03 Iimpawu zekhabhathi ye-electro-optic modulation optical frequency
Inzuzo yokuqala: ukulungiswa
Ekubeni umthombo wokukhanya yilaser ebanzi ehlengahlengiswayo, kwaye i-electro-optical modulator ikwanayo ne-bandwidth ethile yokusebenza kwe-frequency, i-electro-optical modulation optical frequency comb ikwayi-frequency changeable. Ukongeza kwi-frequency changeable, ekubeni i-waveform generation ye-modulator ihlengahlengiswayo, i-frequency ephindaphindwayo ye-optical frequency comb ephumayo nayo iyahlengahlengiswa. Eli lithuba elingenayo i-optical frequency combs eziveliswa yi-mode-locked lasers kunye ne-micro-resonators.
Inzuzo yesibini: ukuphindaphinda rhoqo
Izinga lokuphindaphinda aliguquguquki nje kuphela, kodwa linokufikelelwa ngaphandle kokutshintsha izixhobo zovavanyo. Ububanzi bomgca we-electro-optic modulation optical frequency comb bulingana ne-modulation bandwidth, i-general commercial electro-optic modulator bandwidth yi-40GHz, kwaye i-electro-optic modulation optical frequency comb repetition frequency ingadlula i-optical frequency comb bandwidth eyenziwe zizo zonke ezinye iindlela ngaphandle kwe-micro resonator (enokufikelela kwi-100GHz).
Inzuzo 3: ukubumba ii-spectral
Xa kuthelekiswa ne-optical comb eveliswa ngezinye iindlela, i-optical disc shape ye-electro-optic modulated optical comb imiselwa ngamanani ee-digri zenkululeko, ezifana ne-radio frequency signal, i-bias voltage, i-incident polarization, njl.njl., ezinokusetyenziselwa ukulawula ubunzulu bee-combs ezahlukeneyo ukufezekisa injongo yokubumba i-spectral.
04 Ukusetyenziswa kwe-electro-optic modulator optical frequency comb
Ekusetyenzisweni okusebenzayo kwe-electro-optic modulator optical frequency comb, ingahlulwa ibe yi-single kunye ne-double comb spectra. Isithuba somgca we-single comb spectrum sincinci kakhulu, ngoko ke ukuchaneka okuphezulu kunokufezekiswa. Kwangaxeshanye, xa kuthelekiswa ne-optical frequency comb eveliswa yi-mode-locked laser, isixhobo se-electro-optic modulator optical frequency comb sincinci kwaye sinokulungiswa ngcono. I-double comb spectrometer iveliswa kukuphazamiseka kwee-coherent single combs ezimbini ezine-repetition frequency ezahlukeneyo kancinci, kwaye umahluko kwi-repetition frequency yi-line space ye-interference comb spectrum entsha. Itekhnoloji ye-optical frequency comb ingasetyenziswa kwi-optical imaging, i-ranging, i-thickness measurement, i-instrument calibration, i-arradically waveform spectrum shaping, i-radio frequency photonics, i-remote communication, i-optical stealth njalo njalo.
