I-Photonic Integrated Circuicker (PIC) System

I-Photonic Integrated Circuicker (PIC) System

I-Silicon Photonics isiyalo esisebenzisa izakhiwo zeplanethi ngokususelwa ezintweni ze-silicon ukuqondisa ukukhanya ukuze kufezekiswe imisebenzi ehlukahlukene. Sigxile lapha ekusetshenzisweni kwezithombe ze-silicon ekwakheni ama-transmitters kanye nabamukeli bezokuxhumana kwe-fiber optic. Njengesidingo sokwengeza ukudluliselwa okwengeziwe e-bandwidth enikeziwe, i-footprint enikeziwe, kanye nezindleko ezinikeziwe, ama-Siliman Photonics azwakala ngokwezomnotho. Yengxenye ye-optical,Ubuchwepheshe bokuhlanganiswa kwe-PhotonicKufanele isetshenziswe, futhi ama-transceivers ahambisanayo nanamuhla ayakhiwa kusetshenziswa ama-moduit ahlukene we-linbo3 / planar

Umdwebo 1: Ibonisa ama-Photonic ahlanganisiwe ahlanganisiwe wesifunda (pic)

Umdwebo 1 ukhombisa izinhlelo ezithandwa kakhulu ezibonakalayo ze-pic. Ukusuka kwesobunxele kuye kwesokudla kukhona i-Silica Pic PICA (eyaziwa nangokuthi i-PLC), i-Silicon-based insulator pic (i-Silicon Photonics), i-Lithium Niobate (Linbo3), ne-III-V POP, njenge-ITP naseGaas. Leli phepha ligxile kuma-photonics asuselwa ku-silicon. Phakathi kwa-Ama-Silicon Photonics, Isiginali yokukhanya ikakhulukazi ihamba eSilicon, enayo igebe le-band elingaqondile le-1.12 electron volts (nge-wavelength ka-1,1 microns). I-Silicon ikhule ngesimo sezinhlamvu ezihlanzekile ezithakeni bese igawula ama-wafers, namuhla ango-300 mm ubukhulu. Ingaphezulu le-wafer lisebenza ngo-oxidicated ukwakha ungqimba lwe-silica. Omunye wabahlali ugcwele ama-athomu e-hydrogen ekujuleni okuthile. Ama-wafers amabili afakwe ku-vacuum kanye nezendlalelo zazo ze-oxide zihlangana komunye nomunye. Umhlangano uphula umugqa we-hydrogen ion infantation. Ungqimba lwe-silicon lapho kuqhuma khona-ke uvinjelwe, ekugcineni washiya ungqimba oluncanyana lwe-crystalline si ngaphezulu kwe-silicon "isibambo" esiqongweni se-silica ungqimba. Ama-WaveGuides akhiwa kusuka kuleliya le-crystalline elincanyana. Ngenkathi lezi zenuli ezisuselwa ku-silicon (SOI) zenza ama-wavegonics we-simonics aphansi aphansi kungenzeka, empeleni asetshenziswa kakhulu emibuthanweni yama-CMOs anamandla ngenxa yokuvuza okuphansi okunikezayo.

Kunezindlela eziningi ezingenzeka zama-waveGuides asuselwa ku-silicon abonakalayo, njengoba kukhonjisiwe kuMdwebo 2 Ngokuhlanganisa i-germanium, kungenzeka ukwenzaPhotoDeteectorsnokumuncwa kukagesiama-modulators, futhi mhlawumbe ngisho nampuplifiers yokubona. Ngokudonsa i-silicon, amodulator we-opticalkungenziwa. Ngaphansi kusuka kwesobunxele kuya kwesokudla kukhona Phezulu, ukusuka kwesobunxele kuye kwesokudla, kukhona amamojula we-defeletion, ama-photodeteectors e-germanium, ne-germaniumAma-Optical Amplifiers.

Umdwebo 2: Isigaba sesigaba sochungechunge olususelwa ku-silicon lwe-waveguide, olubonisa ukulahleka okujwayelekile kokusakazeka kanye nama-indices aleveki.
