02imodyuli ye-electro-optickwayeukumodareyitha kwe-electro-optici-optical frequency comb
Umphumo we-Electro-optical ubhekisela kwisiphumo sokuba isalathisi esihlaziyiweyo sokutshintsha kwezinto xa kusetyenziswe indawo yombane. Kukho iintlobo ezimbini eziphambili zempembelelo ye-electro-optical, enye yimpembelelo ephambili ye-electro-optical, eyaziwa ngokuba yi-Pokels effect, ebhekiselele kuguquko lomgca wesalathisi se-refractive kunye nentsimi yombane esetyenzisiweyo. Enye isiphumo sesibini se-electro-optical effect, eyaziwa ngokuba yi-Kerr effect, apho utshintsho kwi-index refractive yezinto eziphathekayo lulingana nesikwere sentsimi yombane. Uninzi lweemodyuli ze-electro-optical zisekelwe kwisiphumo sePokels. Ukusebenzisa i-modulator ye-electro-optic, sinokumodareyitha isigaba sokukhanya kwesiganeko, kwaye ngesiseko sokuguqulwa kwesigaba, ngokuguqulwa okuthile, sinokumodareyitha ubunzulu okanye i-polarization yokukhanya.
Kukho iindidi ezahlukeneyo zeklasikhi, njengoko kubonisiwe kuMfanekiso 2. (a), (b) kunye (c) zizo zonke iimodyuli ezinesakhiwo esilula, kodwa ububanzi bomgca we-optical frequency comb eyenziweyo bukhawulelwe yi-electro-optical. bandwidth. Ukuba i-optical frequency comb ene-repetition frequency frequency iyafuneka, iimodyuli ezimbini okanye ngaphezulu ziyafuneka 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 umphumo we-electro-optical, njengoko kubonisiwe kwi-Figure 3.

03 Electro-optic modulation optical frequency comb iimpawu
I-advanteji enye: ukulungelelana
Kuba umthombo wokukhanya yilaser enokuchukunyiswa ebanzi, kwaye imodyuli ye-electro-optical nayo ine-bandwidth ethile yokusebenza, i-electro-optical modulation optical optical comb nayo iyafundeka. Ukongeza kwi-frequency enokuqhutywa, ekubeni i-waveform ye-modulator iyafundeka, ukuphindaphinda okuphindaphindiweyo kwe-optical frequency comb nayo iyafundeka. Le yinzuzo yokuba ii-combs ze-optical frequency eziveliswa yi-mode-lock lasers kunye ne-micro-resonators ayinayo.
I-Advanteji yesibini: ukuphindaphinda amaza
Umlinganiselo wokuphindaphinda awuguquguquki kuphela, kodwa unokufezekiswa ngaphandle kokutshintsha izixhobo zokulinga. Ububanzi bomgca we-electro-optic modulation i-optical frequency comb iphantse ilingane ne-modulation bandwidth, i-electro-optic modulator bandwidth yezorhwebo jikelele yi-40GHz, kunye ne-electro-optic modulation optical frequency optical comb repetition frequency inokugqithisa i-optical frequency comb bandwidth eyenziweyo. ngazo zonke ezinye iindlela ngaphandle kwe-micro resonator (enokufikelela kwi-100GHz).
I-Advanteji yesi-3: ukubunjwa kwe-spectral
Xa kuthelekiswa ne-optical comb eveliswa ngezinye iindlela, i-optical disc shape ye-electro-optic modulated optical comb igqitywe linani lee-degrees zenkululeko, ezifana ne-radio frequency signal, i-voltage ye-bias, i-polarization yesiganeko, njl. isetyenziselwa ukulawula ubunzulu beekama ezahlukeneyo ukuphumeza injongo yokubunjwa okubonakalayo.
04 Ukusetyenziswa kwe-electro-optic modulator optical frequency comb
Kusetyenziso olusebenzayo lwe-electro-optic modulator optical frequency comb, inokwahlulwa ibe yi-spectra yekama enye kunye nephindwe kabini. Isithuba somgca we-spectrum yekama enye mxinwa kakhulu, ngoko ke ukuchaneka okuphezulu kunokufezekiswa. Kwangaxeshanye, xa kuthelekiswa ne-optical frequency comb eveliswa yimode-locked laser, isixhobo se-electro-optic modulator optical frequency comb sincinci kwaye sisebenza ngcono. I-spectrometer yekama ephindwe kabini iveliswa luphazamiseko lwekama ezimbini ezihambelanayo ezineefrikhwensi zokuphinda-phinda ezahlukileyo, kwaye umahluko kuphindaphindo lwefrikhwensi kukugqagqana komgca we-spectrum entsha yokuphazamiseka. Itekhnoloji ye-Optical comb frequency ingasetyenziswa kwi-imaging ye-optical, ukusuka, ukulinganisa ubukhulu, ukulinganiswa kwesixhobo, ukubunjwa kwe-wave wave spectrum, i-radio frequency photonics, unxibelelwano olukude, i-optical stealth njalo njalo.
