Photonic integrated circuit (PIC) zvinhu system

Silicon photonics chirango chinoshandisa planar zvimiro zvinoenderana nesilicon zvinhu kutungamira mwenje kuti uwane akasiyana mabasa. Isu tinotarisisa pano pakushandiswa kwesilicon photonics mukugadzira ma transmitters uye anogashira efiber optic communications. Sezvo kukosha kwekuwedzera kutapurirana pane yakapihwa bandwidth, yakapihwa tsoka, uye mutengo wakapihwa unowedzera, silicon photonics inova yakanyanya kunaka mune zvehupfumi. Kune chikamu chemaziso,Photonic yekubatanidza tekinorojiinofanira kushandiswa, uye akawanda anowirirana transceivers nhasi akavakwa achishandisa akaparadzana LiNbO3/ planar light-wave circuit (PLC) modulators uye InP/PLC vanogamuchira.

Mufananidzo 1: Inoratidza inowanzo shandiswa photonic integrated circuit (PIC) zvinhu masisitimu.

Mufananidzo 1 unoratidza iyo inonyanya kufarirwa PIC zvinhu masisitimu. Kubva kuruboshwe kuenda kurudyi kune silicon-based silica PIC (inozivikanwawo sePLC), silicon-based insulator PIC (silicon photonics), lithium niobate (LiNbO3), uye III-V boka rePIC, rakadai seInP neGaAs. Iri bepa rinotarisa pane silicon-based photonics. Insilicon photonics, chiedza chechiedza chinonyanya kufamba musilicon, iyo ine gap isina kunanga bhendi ye1.12 electron volts (ine wavelength ye1.1 microns). Silicon inokura muchimiro chekristaro chakachena muchoto uye yozochekwa kuita mawafer, ayo nhasi anowanzo 300 mm mudhayamita. Iyo wafer pamusoro inoiswa oxidized kuita silica layer. Imwe yemawafer inobhombwa nemaatomu ehydrogen kusvika pakadzika. Iwo maviri mawafer anobva asanganiswa mune vacuum uye iwo oxide layers anobatana kune mumwe nemumwe. Gungano rinotsemuka richitevedza mutsara wehydrogen ion implantation. Siricon layer iri pakatsemuka inobva yapepereswa, yozopedzisira yasiya chidimbu checrystalline Si pamusoro peiyo silicon "mubato" wafer pamusoro pe silica layer. Mawaveguides anoumbwa kubva pane iyi nhete yekristaro. Nepo aya masilicon-based insulator (SOI) mawafers achigadzira yakaderera-kurasikirwa nesilicon photonics waveguides inogoneka, iwo anonyanya kushandiswa mune yakaderera-simba CMOS maseketi nekuda kwekuderera kwekudonha kwazvino kwavanopa.

Kune akawanda anokwanisika mafomu esilicon-based optical waveguides, sezvakaratidzwa muFigure 2. Iwo anobva ku microscale germanium-doped silica waveguides kusvika nanoscale Silicon Wire waveguides. Nekusanganisa germanium, zvinokwanisika kugadziraphotodetectorsuye kutorwa kwemagetsimodulators, uye pamwe kunyange optical amplifiers. Nekuita doping silicon, anOptical modulatorinogona kuitwa. Pazasi kubva kuruboshwe kuenda kurudyi ndeiyi: silicon wire waveguide, silicon nitride waveguide, silicon oxynitride waveguide, gobvu silicon ridge waveguide, nhete silicon nitride waveguide uye doped silicon waveguide. Pamusoro, kubva kuruboshwe kuenda kurudyi, kune depletion modulators, germanium photodetectors, uye germanium.Optical amplifiers.

Mufananidzo 2: Muchinjikwa-chikamu chesilicon-based optical waveguide series, ichiratidza zvakajairwa kupararira kurasikirwa uye refractive indices.
