Amapharamitha ayisihluthuleloI-modulator ye-Mach Zehnder
I-Mach Zehnder Modulator (i-MZM Modulator) iyi-modulator esezingeni eliphezului-modulator yokuqina kwe-electro-opticyathuthukiswa ngokusekelwe esimisweni sokuphazamiseka kokukhanya. Iyingxenye yegatsha elibalulekile le-ukuguqulwa kwe-electro-opticohlelweni lobuchwepheshe bokushintshashintsha kwe-optical. Njengamanje, imikhiqizo evamile ilungiswa kusetshenziswa ubuchwepheshe be-lithium niobate (LiNbO3) optical waveguide. Ngezinzuzo zayo ezintathu zokusebenza eziyinhloko ze-ultra-low chirp, i-ultra-high extinction ratio, kanye ne-ultra large modulation bandwidth, isibe umkhiqizo wokushintshashintsha oqashelwayo emikhakheni yokuxhumana kwe-backbone fiber optic ekude, ukuxhumana okuqondile kwe-optical, ukukhiqizwa kwe-optical frequency comb, kanye nezinhlelo ze-laser ezisheshayo.
1, amapharamitha abalulekile:
1.1 Ubude besikhathi obusebenzayo: 1310nm/1550nm okwamanje kuyindlela ethandwa kakhulu emkhakheni wokuxhumana
1.2 I-voltage yesigamu segagasi V π: Imikhiqizo ye-waveguide yezentengiselwano ngokuvamile ilawulwa ngaphakathi kwama-5V. Uma i-voltage yesigamu segagasi iphansi, kulapho izindleko zokushayela zedivayisi ehambisanayo ziphansi khona.
1.3 Ububanzi bokushintshashintsha: Njengamanje, imikhiqizo yezentengiselwano ihlukaniswe kakhulu ngamazinga ahlukene e-40G/80G/120GHz;
1.4 Isilinganiso sokuphela: Isilinganiso sokuphela kwemikhiqizo esezingeni eliphezulu singafinyelela ngaphezu kwama-25dB, kanye nokusebenza okuphakeme kakhulu kune-EAM
1.5 Ukulahlekelwa kokufakwa: Inani elijwayelekile liphakathi kuka-3 ~ 4.5dB;
1.6 I-Chirp Coefficient: Imikhiqizo esebenza kahle kakhulu ingafinyelela cishe ukungabi nalutho kwe-chirp, okuyinzuzo yayo eyinhloko ezimweni zokudlulisa ibanga elide.
2. Ukuhlukaniswa komkhiqizo:
2.1 Ngemodi yokushayela: ukuguqulwa kwengalo eyodwa, ukuguqulwa kwengalo ephindwe kabili (okujwayelekile ensimini yokuxhumana, ngokuhleleka okungcono);
2.2 Ngomsebenzi: Amandla ajwayelekileI-MZM Modulator, i-IQ ehlanganisiwe ye-MZM Modulator (enikezelwe ukuxhumana okuhlangene, ehlanganiswe yi-orthogonal dual MZM Modulator.
2.3 Imikhiqizo yezentengiselwano isekelwe kakhulu ekucushweni kwe-waveguide ehlanganisiwe, ukusebenza okulinganiselayo kanye nokuqina kokukhiqiza ngobuningi.
3. Izimo zokusetshenziswa:
Ukumboza inethiwekhi yomgogodla amamojula okukhanya akude angu-400G/800G/1.6T, ukuzwa kwe-radar/fiber okuhlanganisiwe, ukulungiswa kwe-laser mode locking/optical frequency combination, ukulawula isigaba sokuxhumana kwe-quantum kanye neminye imikhakha.
4. Umkhuba wokuthuthukiswa:
Ukuqhubekela phambili ekwenzeni i-lithium niobate MZM modulator ibe yincane futhi kukhiqizwe ngobuningi ama-modulator ahlanganisiwe e-MZM asekelwe ku-silicon, kufezwe ukunciphisa izindleko kanye nokuthuthukiswa kokusebenza kahle, kanye nokwandisa izimo eziningi zokusetshenziswa.
