Magadzirirwo akakosha eMach Zehnder modulator

Zvikamu zvikuru zveMach Zehnder modulator
Mach Zehnder Modulator (MZM Modulator) imhando yepamusoro-soromodulator yesimba remagetsi-opticyakagadzirwa zvichibva papfungwa yekupindira kwemaziso. Ndeyebazi rakakosha remodulation yemagetsi-opticmuhurongwa hwe tekinoroji ye optical modulation. Parizvino, zvigadzirwa zvikuru zvinogadzirwa uchishandisa tekinoroji ye lithium niobate (LiNbO3) optical waveguide. Nekubatsira kwayo kukuru kwe ultra-low chirp, ultra-high extinction ratio, uye ultra large modulation bandwidth, yave chigadzirwa chinozivikanwa che benchmark modulation muminda ye long-distance backbone fiber optic communication, coherent optical communication, optical frequency comb generation, uye ultrafast laser systems.
1, Zviyero zvakakosha:
1.1 Kureba kwehurefu hwemasaisai: 1310nm/1550nm parizvino ndiyo sarudzo huru munyaya dzekutaurirana
1.2 Voltage yehafu yemafungu V π: Zvigadzirwa zvemafungu ekutengeserana zvinowanzo dzorwa mukati me5V. Kana voltage yehafu yemafungu yakaderera, mutengo wekutyaira wemudziyo unoenderana nawo unoderera.
1.3 Kuchinja kwebandwidth: Parizvino, zvigadzirwa zvekutengeserana zvakakamurwa zvakanyanya muzvikamu zvakasiyana zve40G/80G/120GHz;
1.4 Chiyero chekutsakatika: Chiyero chekutsakatika kwezvigadzirwa zvemhando yepamusoro chinogona kusvika pamusoro pe25dB, nekushanda kwakakwirira kupfuura EAM
1.5 Kurasikirwa kwekuisa: Kukosha kwakajairika kuri pakati pe3 ~ 4.5dB;
1.6 Chirp Coefficient: Zvigadzirwa zvine mashandiro akanaka zvinogona kuita chirp isina kana chinhu, inova ndiyo mukana wazvo mukuru mukutumira ma "transmission" ari kure.
2. Kurongwa kwechigadzirwa:
2.1 Nekushandisa nzira yekutyaira: kuchinjisa ruoko rumwe chete, kuchinjisa ruoko ruviri (kunonyanya kushandiswa mukukurukurirana, nemutsara uri nani);
2.2 Nebasa: Simba rakajairikaModulator yeMZM, IQ yakabatanidzwa MZM Modulator (yakatsaurirwa kutaurirana kwakabatana, yakabatanidzwa ne orthogonal dual MZM Modulator.
2.3 Zvigadzirwa zvekutengeserana zvinonyanya kuenderana nehurongwa hwemafungu akabatanidzwa, kushanda kwakaringana uye kugadzikana kwekugadzirwa kwehuwandu.

3. Mamiriro ekushandisa:
Kuvhara network yemusana 400G/800G/1.6T ma module e optical akareba, coherent optical radar/fiber sensing, ultrafast laser mode locking/optical frequency comb preparation, quantum communication phase control nedzimwe nzvimbo.
4. Mafambiro ekuvandudza:

Kufambira mberi pakuita kuti simbi ye lithium niobate MZM modulator ive shoma uye kugadzira simbi dzakawanda dzinoshandisa silicon-based MZM modulator, kuderedza mitengo nekuvandudza mashandiro, uye kuwedzera mikana yekushandisa.
