Imikorere minini electro-optic modulator: Filime yoroheje lithium niobate modulator

Imikorere minini ya electro-optic modulator:film yoroheje lithium niobate modulator

Modutor ya electro-optique (EOH Modulator) Ese modulator yakozwe hakoreshejwe ingaruka za electro-optique ya optique ya electro-optique, ishobora guhindura ibimenyetso byihuta bya elegitoroniki mubikoresho byitumanaho muburyo bwa optique. Iyo electro-optic Crystal ikorerwa umurima wamashanyarazi, urutonde rwa electique ya electro-optique irahinduka, kandi kugirango umenye ibimenyetso byihuse bya Electurique, hanyuma umenye ibimenyetso byihuta bya Electurique, hanyuma ugire icyo uhindura ibimenyetso bya opturike, hanyuma ugire icyo uhindura ibimenyetso bya oplique, hanyuma ugire icyo uhindura ibimenyetso bya opturique, hanyuma umenye ibimenyetso byihuta bya elegique, hanyuma ugaragaze ibimenyetso byihuta bya elegital mubimenyetso byitumanaho muburyo bwiza.

Kugeza ubu, hariho ubwoko butatu bwingenzi bwaAmashanyarazi ya electro-opticku isoko: Abagenzi baho ba Silicon, Modulatori ya Indium na firime yorohejelithium niobate modulator. Muri bo, Silicon ntabwo ifite serivisi zitaziguye, imikorere ni rusange, gusa ikwiranye no gufatanya na Trasceile Itumanaho rya Transcelaine Ibinyuranye, lithium niobate kristu ntabwo ari abakire mubikorwa bya Phofeterictric, shiraho ingaruka zamafoto, kandi quitique ifite ingaruka nziza, ibintu byinshi bya Nioumu birashobora kugengwa nabyo, ibimenyetso, Kugenzura leta, nibindi. Nk'ibice bya fototeri-electro-optique kugeza kuri 30.9pm / hejuru cyane (ingaruka ntoya (Ingaruka ntoya (Ingaruka nini ya Chirp. Ingaruka), igipimo cyiza cyo kuzenguruka (Ikigereranyo cyamashanyarazi cyikimenyetso "kuri" leta kugeza "OFF"), hamwe nigikoresho cyisumbuye. In addition, the working mechanism of the thin film lithium niobate modulator is different from that of the silicon-based modulator and indium phosphide modulator using nonlinear modulation methods, which uses linear electro-optical effect to load the electrically modulated signal onto the optical carrier, and the modulation rate is mainly determined by the performance of the microwave electrode, so higher modulation speed and linearity as well Nkuko gukoresha imbaraga zo hasi birashobora kugerwaho. Ukurikije ibyavuzwe haruguru, Litithium niobate nziza yo gutegura modulator yo hejuru ya elegique, ifite amakuru menshi yo gutumanaho hamwe na ultra-yihuta-yihuta, kandi irashobora kugera kuri kilometero zirenga 100.

Lithium niobate nk'ibikoresho byo guhirika "Impinduramatwara ya Photon", nubwo ugereranije na fosifika ya silicon na Indium igaragara mu indege yagabanijweho cyangwa igenamiterere rya SPOST risanzwe (hafi 0.02), ingano y'ibikoresho irakomeye. Biragoye kuzuza ibikenewe byo gucura no kwishyira hamwe kwaIbikoresho bya Optique, n'umurongo wacyo utanga umusaruro uracyatandukanye numurongo wa microelectronics umurongo, kandi hari ikibazo cyikiguzi kinini, bityo habaho firime yoroheje nicyerekezo cyiterambere cyingenzi kuri lithium niobate ya electro-optique.
