Magawo ofunikira aMach Zehnder modulator
Mach Zehnder Modulator (MZM Modulator) ndi kampani yapamwamba kwambirimodulator ya mphamvu ya electro-opticYapangidwa kutengera mfundo ya kusokoneza kwa kuwala. Ili m'gulu lofunika kwambiri lakusintha kwa magetsi ndi kuwalaMu njira yaukadaulo wa optical modulation. Pakadali pano, zinthu zazikulu zimakonzedwa pogwiritsa ntchito ukadaulo wa mafunde a lithiamu niobate (LiNbO3). Ndi ubwino wake waukulu wa magwiridwe antchito atatu a ultra-low chirp, ultra-high extinction ratio, ndi ultra large modulation bandwidth, yakhala chinthu chodziwika bwino cha modulation m'magawo a kulumikizana kwa backbone fiber optic kwakutali, kulumikizana kwa coherent optical, kupanga ma frequency optical comb, ndi machitidwe a laser othamanga kwambiri.
1, magawo Ofunika:
1.1 Kutalika kwa nthawi yogwira ntchito: 1310nm/1550nm pakadali pano ndiye chisankho chachikulu pankhani yolumikizirana
1.2 Voliyumu ya theka la mafunde V π: Zogulitsa zama waveguide zamalonda nthawi zambiri zimayendetsedwa mkati mwa 5V. Voliyumu ya theka la mafunde ikatsika, mtengo woyendetsera chipangizocho umachepa.
1.3 Kusinthasintha kwa liwiro: Pakadali pano, zinthu zamalonda zimagawidwa m'magawo osiyanasiyana a 40G/80G/120GHz;
1.4 Chiŵerengero cha kutha kwa zinthu: Chiŵerengero cha kutha kwa zinthu zapamwamba chimatha kufika pa 25dB, ndipo magwiridwe antchito ndi apamwamba kwambiri kuposa EAM
1.5 Kutayika kwa kuyika: Mtengo wamba uli pakati pa 3 ~ 4.5dB;
1.6 Chirp Coefficient: Zogulitsa zomwe zimagwira ntchito bwino kwambiri zimatha kulephera kugwiritsa ntchito chirp, zomwe ndi phindu lawo lalikulu pazochitika zotumizira magiya akutali.
2. Gulu la zinthu:
2.1 Pogwiritsa ntchito njira yoyendetsera galimoto: kusintha kwa mkono umodzi, kusintha kwa manja awiri (komwe kumagwiritsidwa ntchito kwambiri pakulankhulana, ndi mzere wabwino);
2.2 Ndi ntchito: Mphamvu wambaMZM Modulator, IQ integrated MZM Modulator (yoperekedwa kuti ilumikizane bwino, yolumikizidwa ndi orthogonal dual MZM Modulator.
2.3 Zogulitsa zamalonda zimadalira kwambiri makonzedwe ophatikizidwa a ma waveguide, magwiridwe antchito olinganiza komanso kukhazikika kwa kupanga zinthu zambiri.

3. Zochitika zogwiritsira ntchito:
Kuphimba netiweki ya msana 400G/800G/1.6T ma module akutali a optical, coherent optical radar/fiber sensing, ultrafast laser mode locking/optical frequency comb preparation, quantum communication phase control ndi zina.
4. Kukula kwa zinthu:

Kupita patsogolo pa kuchepetsa mphamvu ya lithiamu niobate MZM modulator komanso kupanga ma modulators a MZM ophatikizidwa ndi silicon, kuchepetsa ndalama ndi kukonza magwiridwe antchito, ndikukulitsa njira zambiri zogwiritsira ntchito.
