Photonic sib xyaw Circuit Court (pic) khoom siv

Silicon photonics yog kev qhuab qhia uas siv cov qauv npaj rau cov khoom silicon kom ua tiav lub teeb ua haujlwm kom ua tiav ntau lub luag haujlwm. Peb tsom mus rau ntawm daim ntawv thov ntawm silicon photonics hauv kev tsim cov transmitters thiab tau txais rau fiber ntau kev sib txuas lus. Raws li qhov yuav tsum tau ntxiv cov kev sib kis ntxiv rau ntawm ib bandwidth, tus muab hneev taw, thiab tus nqi muab nqi nce, silicon particically ua suab nrov. Rau qhov kho qhov muag,Photonic Mote TechnologyYuav tsum tau siv, thiab kev hloov pauv kev sib kis niaj hnub no tau tsim tsa Linbo3 / PlC Circuit Court (PLC) Modulators thiab Inp / PLC cov neeg tau txais.

Daim duab 1: Pom feem ntau siv potoronic sib xyaw Circuit Court (pic) cov khoom siv tshuab.

Daim duab 1 qhia tau cov khoom nrov tshaj plaws ntawm cov xov tooj. Los ntawm sab laug mus rau txoj cai yog silica pic (tseem hu ua plc), lithium niobate (linbo3, xws li inp thiab Gaas. Daim ntawv no tsom rau silicon-based photonics. Hauvsilicon partonics, lub teeb liab teeb liab tsuas yog taug kev hauv silicon, uas muaj kev sib tw band ntawm 1.12 electron volts (nrog nthwv dej ntawm 1.1 microns). Silicon yog zus nyob rau hauv daim ntawv ntawm cov ntshiab muaju nyob rau hauv cov chaw ua kom sov thiab tom qab ntawd txiav rau hauv wafers, uas niaj hnub no feem ntau yog 300 mm hauv lub taub. Cov wafer saum yog oxidized los ua ib txheej Silica Silica. Ib qho ntawm wafers yog foob pob nrog hydrogen atoms rau ib qho tob. Ob wafers yog fused fused hauv lub tshuab nqus tsev thiab lawv cov roj oxide rau ib leeg. Lub rooj sib txoos rhuav tshem raws cov kab hydrogen ion immantation. Silicon txheej ntawm qhov tawg yog ces polished, thaum kawg tawm ntawm nyias txheej ntawm crystalline Siystaloo "kov" wafer nyob rau sab saum toj ntawm cov silica txheej. WaveGuides yog tsim los ntawm cov txheej nyias crystalline txheej. Thaum cov pob zeb ua sivera (soi) wafers ua rau cov khoom lag luam silicon potonics ntau zaus nyob rau hauv batt-zog cmos circuits vim hais tias ntawm cov xau dej tam sim no lawv muab.

Muaj ntau cov ntaub ntawv ua tau ntawm silicon-based kho qhov muag, raws li muaj nyob hauv daim duab 2. Lawv ntau yam los ntawm microscale se silica flalgingides rau nanoscale silicon xaim yoj waveguides. Los ntawm kev sib xyaw ua ke hauv German, nws muaj peev xwm ua tauphotodetectorsthiab hluav taws xob tsis nqusmodulators, thiab tejzaum nws tseem kho kho kom zoo tshaj plaws. Los ntawm doping silicon, ibKho qhov muagtuaj yeem ua tau. Hauv qab los ntawm sab laug rau sab xis yog: Silicon WaveGuide, silicon Oxynitride WaveGuide, Thias silicon nitride waveguide thiab doped silicon stride. Nyob rau sab saum toj, los ntawm sab laug rau sab xis, yog qhov chaw ua haujlwm modulators, germanium photodetors, thiab GermaniumKho Qhov Kho Kom Zoo Nkauj.

Daim duab 2: Hla-ntu ntawm cov khoom cua sov-raws li cov khoom siv hluav taws xob waveGuide thiab cov uas poob haujlwm thiab cov khoom lag luam tsis zoo.
