Electro-optic modulatorndicho chinhu chakakosha chekugadzirisa inoenderera mberi laser siginecha uchishandisa data, redhiyo frequency uye wachi masaini.Zvimiro zvakasiyana zvemodulator zvine mabasa akasiyana.Kuburikidza neiyo optical modulator, kwete chete kusimba kwemwenje wave kushandurwa, asiwo chikamu uye polarization mamiriro emwenje wave anogona kugadziridzwa.Inonyanya kushandiswa electro-optic modulators ndeye Mach-Zehnderintensity modulatorsuyephase modulators.
TheLiNbO3 intensity modulatorinoshandiswa zvakanyanya mu-high-speed optical communication system, laser sensing uye ROF masisitimu nekuda kweiyo electro-optic performance.Iyo R-AM yakatevedzana yakavakirwa paMZ kusunda-kudhonza chimiro uye X-yakatemwa dhizaini, ine yakagadzikana yemuviri uye kemikari hunhu, iyo inogona kuiswa mune zvese murabhoritari kuyedza uye maindasitiri masisitimu.
Modulator mhando
Wavelength: 850nm/1064nm/1310nm/1550nmn

Zvimwe: High ER Intensity Modulator/CascadingMZ Modulator/Dual-parallel MZ Modulator
Feature:
Kurasikirwa kwekuisa pasi
Yakaderera hafu-voltage
Kugadzikana kwepamusoro
Application:
ROF masisitimu
Quantum kiyi yekugovera
Laser inonzwa masisitimu
Side-bhendi modulation
Zvinodikanwa zvehuwandu hwekutsakatika kwepamusoro
1. System modulator inofanira kuva nepamusoro-soro yekutsakatika.Hunhu hwesystem modulator inosarudza iyo yakanyanya kutsakatika reshiyo inogona kuwanikwa.
2. Polarization yemodulator yekuisa mwenje ichachengetwa.Modulators anonzwa kune polarization.Polarization yakakodzera inogona kuvandudza kutsakatika kwechiyero pamusoro pe10dB.Mukuedza kweLab, kazhinji polarization controller inodiwa.
3. Vatariri vakarerekera vakakodzera.Mune yedu DC extinction ratio kuyedza, 50.4dB yekudzima reshiyo yawanikwa.Nepo dhetabheti yemodulator inogadzira inonyora 40dB chete.Chikonzero chekuvandudzwa uku ndechekuti mamwe ma modulators anokukurwa nekukurumidza.Rofea R-BC-CHENYI madhiraivha ekurerekera anovandudza bias voltage pasekondi imwe yega yega kuti ive nechokwadi chekukurumidza kupindura.
ROF yakave yakatarisana ne electro-optic yakabatanidzwa maseketi uye zvikamu kwemakore gumi.Isu tinogadzira yakakwirira-inoshanda yakabatanidzwa-optical modulators uye tinopa mhinduro nyowani uye masevhisi kune vese vaongorori vesainzi uye mainjiniya eindasitiri.Iwo ma modulators eRofea ane yakaderera drive voltage uye yakaderera yekuisa kurasikirwa yainyanya kushandiswa muhuwandu hwekugovera kiyi, radio-pamusoro-fiber masisitimu, laser sensing masisitimu, uye inotevera-chizvarwa optical telecommunication.
Isu tinopawo akawanda ma modulator ekugadzirisa, akadai se 1 * 4 array phase modulators, Ultra-low Vpi, uye ekupedzisira-yepamusoro yekutsakatika ratio modulators, inonyanya kushandiswa mumayunivhesiti nemasangano.Pamusoro pezvo, isu zvakare tinogadzira RF amplifier (modulator mutyairi) uye BIAS controller, photonics detector nezvimwe.
Mune ramangwana, isu ticharamba tichivandudza chiripo chigadzirwa chakatevedzana, kuvaka timu yehunyanzvi tekinoroji, ramba uchipa vashandisi mhando yepamusoro, yakavimbika, zvigadzirwa zvepamberi uye masevhisi ehunyanzvi.
