Iphephwini ye-Siliconizinto ezidlulayo
Kukho izinto ezininzi eziphambili ezihambayo kwi-selicon phetonics. Elinye lala mazwi okugcina indawo, njengoko kubonisiwe kumzobo 1A. Ine-Grating enamandla kwi-waveguide olixesha elimalunga ne-wavelength yamaza okukhanya kwi-waveguide. Oku kuvumela ukukhanya ukuba kukhutshwe okanye kufunyanwe ubugqi kumphezulu, kuyenza ilungele imilinganiselo yenqanaba le-wafer-kunye / okanye inxibelelanisa kwifayibha. Abatshati abathintelayo bahlukile kwi-selicon ze-selicon ze-selicon kuba zifuna isahlulo esiphezulu sesalathiso. Umzekelo, ukuba uzama ukwenza isibini esithandanayo kwi-Inp WaveGuide, ukukhanya kuyavuza ngokuthe tye endaweni yokuba kukhutshwe isalathiso esisezantsi sesalathiso esincinci sesandiso. Ukuyenza isebenze kwi-Inp, izixhobo kufuneka zikhutshwe phantsi kolawulo lokumisa, njengoko kubonisiwe kumzobo 1B.
Umzobo 1: Ukukhuphela i-ofisi yomgangatho omnye wokuThunyelwa kweNdawo kwiSilicon (A) kunye ne-Inp (B). Ku (a), i-grey kunye neblowu ibala i-silicon kunye ne-silica, ngokulandelelana. Kwi (b), ibomvu kwaye i-orenji imele i-zungus kunye ne-inp, ngokulandelelana. Amanani (c) kwaye (d) askena imifanekiso ye-elektroniki (i-SM) ye-InP ye-Inp ye-Inp enqunyanyisiweyo.
Elinye icandelo eliphambili ngumguquli wobungakanani bebala (i-SSC) phakathi kweI-Optical WapeGuidekunye nefayibha, eziguqula imowudi malunga ne-0.5 × 1 × 1 μm2 kwi-Silicon WaveGuide kwimowudi malunga ne-10 × 10 μm2 kwifayibha. Indlela yesiqhelo kukusebenzisa isakhiwo esibizwa ngokuba yi-taper engenanto, apho amaWaveGiide ethe chu kwincam encinci, ekhokelela ekukhuleni kwei-opticalImowudi yendlela. Le ndlela inokufakwa yiglasi yeglasi enqunyanyisiweyo, njengoko kubonisiwe kumzobo 2. Nge-SSC enjalo, ilahleko yokudibanisa okungaphantsi kwe-1.5DB ifezekisiwe ngokulula.
Umzobo 2: Ipateni ye-pather yomguquli we-silicon wire wavegogides. Izixhobo ze-silicon zenza isakhiwo esingafaniyo ngaphakathi kwiglasi yeglasi enqunyanyisiweyo. I-selicon Cardrest ikhutshiwe phantsi kweglasi yeglasi enqunyanyisiweyo.
Icandelo eliphambili lezinto eziphambili ngumbala we-polarial proptter. Eminye imizekelo ye-polarization iboniswa kumzobo 3. Eyokuqala yi-Mate-Ze-Zeninder Prefermeter (Mzi), apho ingalo nganye ineengalo ezahlukeneyo. Okwesibini sisibini esilula esilula. Ubume bayo bune-bire wire wire wire wire wiregege right iphezulu kakhulu, ngoko ke ukukhanya kwemagnethi (tserner off. Okwesithathu sisibini sokuzala, apho i-fiber ifakwe khona kwi-engile ukuze kukhanye ukuqaqanjelwa ngokudibeneyo kwicala elinye kunye nokukhanya kwento ethengiswayo. Elesine sisitshati esinemilinganiselo emibini. Iimodi ze-fiber amasimi awo umbane avela kwicala lokusasazeka kwe-waveGide idityaniswa kwi-waveGuide ehambelanayo. Ifayibha inokutsalwa kwaye idityaniswe ukuya kuthi ga kwi-waveegides ezimbini, okanye i-perpendicular ukuya kumphezulu kwaye zidityaniswe kwi-wavegagides ezine. Inzuzo eyongeziweyo yabatshati ababini abatshatileyo kukuba basebenza njengamahlelo lokulinganisa, oko kuthetha ukuba zonke izibane kwi-chip zinokusetyenziswa ngendlela efanayo, kodwa iindlela ezimbini ze-orthogonal zisetyenziswa kwifayibha.
Umzobo 3: I-Polick Polifters Prelization.
