Ungasarudza sei pakati pe780nm phase modulator uye intensity modulator?

Maitiro ekusarudza pakati pe780nmmodulator yechikamuuye modulator yesimba?
Muhuwandu hwemafungu e780nm, kudyidzana pakati pechiedza nezvinhu kwakanyanya - kungave kuchinja kwemutsara weD2 wemaatomu ecesium kana kushandurwa kwequantum state kwemaatomu erubidium, kudzora kwakarurama kwelaser muhuwandu hwemafungu aya kwakakosha. Chishandiso chikuru chinoita kuti mutemo uyu ushande ielectro-optic modulator (Modulator yeEOMPakati pavo, kunyange zvazvo vese vari vavirimodulator yechikamu chemagetsi-opticuye electro-opticmodulator yesimbaVari vemhuri ye lithium niobate electro-optic modulation, vane hunyanzvi hwavo hwakasiyana uye vanoita mabasa avo.
Electro optic phase modulator, sezita rayo, inotarisa pakudzora kwakarurama kwechikamu chezviratidzo zve optical. Maumbirwo ayo akareruka - waveguide imwe chete inosanganiswa nema electrodes maviri kumativi ese, uye refractive index yekristaro inoshandurwa kuburikidza ne electro-optic effect, nokudaro ichichinja chikamu che light wave. ROF-PM series 780nm phase modulator inoshandisa tekinoroji yepamusoro yeproton exchange uye ine hunhu hwakanaka hwakadai sekurasikirwa kwakaderera kwekuisa (kwakajairika kukosha 2.8dB), high modulation bandwidth (10GHz), uye low half wave voltage (kwakajairika kukosha 2.0V). Inonyanya kushanda muminda ye space optical communication systems, cesium atomic time reference, spectral broadpening, uye interferometry - mu optical clocks uye precision measurements, phase modulators ndiwo "magamba ekuseri kwezviitiko" ekukiya frequency uye stabilization.
Iyomodulator yesimba remagetsi-opticine basa rekutonga simba (amplitude) rechiedza. Yakavakirwa paMach Zehnder interferometer (MZI) structure: optical signal yakakamurwa kuita nzira mbiri, idzo dzinopinda mu phase modulation dzobva dzabatanidzwazve, zvichiita kuti simba riwedzere kuburikidza ne interference effects. ROF-AM-07 series intensity modulator inoshandisawo proton exchange technology, ine insertion loss iri pasi pe3dB, switch extinction ratio inosvika 23dB, uye typical half wave voltage ye3V chete paRF end. Mashandisirwo ayo akajairika anofukidza space optical communication, quantum optics, pulse generators, nedzimwe nzvimbo - mu quantum information experiments, intensity modulators dzinowanzo shandiswa "kucheka" continuous lasers kuita nanosecond level optical pulses.
Zvinogona kutaurwa kuti phase modulator ndiye muimbi anonatsa phase yemafungu echiedza zvakanaka, nepo intensity modulator ari mukuru anodzora kusimba kwechiedza zviri nyore. Mbili idzi dzinobatsirana, dzese dzichitsigira tail fibers dzakagadzirwa dzeFC/PC neFC/APC, nekushanda kwakasimba pakupisa kwakakura kwe -10 ℃ ~ 60 ℃, dzichifukidza nzira dzakawanda dzekuedza dze optical kubva kumaatomu eatomic wachi kusvika kuma quantum optics epamusoro, zvichipa mhinduro yekubatanidza optical modulation ye 780nm band research.
