Modulator yeElectro-opticndiyo chinhu chikuru chekugadzirisa chiratidzo chelaser chinoramba chichienderera mberi uchishandisa data, radio frequency uye clock signals. Maumbirwo akasiyana emodulator ane mabasa akasiyana. Kuburikidza ne optical modulator, simba remafungu echiedza rinogona kuchinjwa kwete chete, asiwo phase uye polarization state ye light wave inogona kugadziriswa. Ma electro-optic modulators anonyanya kushandiswa ndeaya: Mach-Zehndermamodulator esimbauyemamodulator echikamu.
IyoModulator yesimba reLiNbO3Inoshandiswa zvakanyanya muhurongwa hwekukurukurirana hwe optical hunomhanya zvakanyanya, laser sensing uye ROF systems nekuda kwekushanda kwayo zvakanaka kwe electro-optic. R-AM series yakavakirwa paMZ push-pull structure uye X-cut design, ine hunhu hwakagadzikana hwe physical uye chemical, hunogona kushandiswa mukuyedza murabhoritari uye mumaindasitiri systems.

Zvinodiwa kuti pave nehuwandu hwakawanda hwekutsakatika kweropa
1. System modulator inofanira kunge iine high disappency ratio. Hunhu hwesystem modulator hunosarudza kuti high disappency ratio inogona kuwanikwa.
2. Kugadziriswa kwechiedza che modulator kunofanira kugadziriswa. Ma modulator anonzwa kukanganiswa nekugadziriswa kwe polar. Kugadziriswa kwakakodzera kunogona kuwedzera chiyero chekutsakatika kwechiedza kupfuura 10dB. Mukuyedza kwerabhoritari, kazhinji muchina wekutonga kudzorwa kwechiedza unodiwa.
3. Vatongi vebias vakakodzera. Mukuyedza kwedu DC extinction ratio, 50.4dB extinction ratio yakawanikwa. Kunyange zvazvo datasheet yemugadziri wemodulator iine 40dB chete. Chikonzero chekuvandudzwa uku ndechekuti mamwe mamodulator anongomhanya nekukurumidza. Rofea R-BC-ANY bias controllers inogadzirisa bias voltage sekondi imwe chete kuti ive nechokwadi chekuti mhinduro inokurumidza.
ROF yave ichinyanya kutarisana nema electro-optic integrated circuits pamwe ne components kwemakore gumi. Isu tinogadzira high-performance integrated-optical modulators uye tinopa mhinduro itsva uye masevhisi kune vese vaongorori vesainzi nemainjiniya eindasitiri. Ma modulators eRofea ane low drive voltage uye low insertion loss ainyanya kushandiswa mu quantum key distribution, radio-over-fiber systems, laser sensing systems, uye next-generation optical telecommunication.
Tinopawo ma modulators akawanda ekugadzirisa, akadai se 1*4 array phase modulators, ultra-low Vpi, uye ultra-high extinction ratio modulators, anoshandiswa zvakanyanya mumayunivhesiti nemasangano. Pamusoro pezvo, tinogadzirawo RF amplifier (modulator driver) uye BIAS controller, photonics detector nezvimwewo.
Mune ramangwana, ticharamba tichivandudza zvigadzirwa zviripo, kuvaka timu yehunyanzvi yehunyanzvi, kuramba tichipa vashandisi zvigadzirwa zvemhando yepamusoro, zvakavimbika, zvepamusoro uye masevhisi ehunyanzvi.
