Silicon photonicsPassive zvikamu
Pane akati wandei kiyi yekupaza zvikamu muSilicon Phototics. Imwe yeizvi ndeyekuburitsa chikamu cheGomer Complik, sezvakaratidzwa mumufananidzo 1a. Iyo ine yakasimba kuremara kwakasimba muhuwandu hwesguide ane nguva yakanangana neyakaenzana neiyo wavelength yechiedza chichava muimbi. Izvi zvinobvumira kuti mwenje ubudiswe kana kugashirwa perpendicular kune pamusoro, uchiita kuti zvive zvakanaka kune wafer-lever-level zviyero uye / kana kuwirirana neiyo fiber. Grating Couplers idzo dzakasarudzika kune yakasarudzika silicon photonics mune izvo zvavanoda yakanyanya vertical index musiyano. Semuenzaniso, kana iwe ukaedza kuita grating coupler mune yakajairika Inp Waveguide, iyo mwenje inodonha zvakananga pane yakabviswa nekuti iyo Grow Wasguide ine yakaderera avhareji yekudzora index pane substrate. Kuti iite kuti ishande musizi, zvinhu zvinofanirwa kuve zvichikundwa pasi pegwenzi kuti dzimise, sezvakaratidzwa mumufananidzo 1b.
Mufananidzo 1: Kumusoro-kubvisa imwe-dimensional Grating Couplers muSilicon (a) uye inp (b). Mu (a), grey uye mwenje yebhuruu inomiririra silicon uye silika, zvichiteerana. Mu (b), tsvuku uye orenji zvinomiririra Ingaasp uye Inp, zvichiteerana. Manhamba (c) uye (d) ari kuongorora Electron microscope (sem) mifananidzo ye inp yakamiswa Cantilever grating canlinesr.
Imwe kiyi chikamu ndiyo nzvimbo yakasarudzika inoshandura (SSC) pakati peOptical WasguideUye fiber, iyo inoshandura maitiro emakore 0,5 × 1 Nzira yakajairika ndeye kushandisa chimiro chinonzi itsve in the typer, umo iyo waveguide zvishoma nezvishoma marara kune diki diki, iyo inoguma nekuwedzera kwakakura kweOpticalmode chigamba. Iyi nzira inogona kubatwa negirazi rakamiswa waveguide, sezvakaratidzwa mumufananidzo 2
Mufananidzo 2: Mukuru wezasi unoshandura silicon wire waveguides. Iyo silicon zvinyorwa zvinoumba iyo inverse conical dhizaini mukati megirazi remagirazi rekuwedzera. Iyo silicon substrate yakamiswa pasi pasi pegirazi remagirazi rekuimbira.
Iyo kiyi inokatyiswa chikamu ndeyekupuruzika beam splitter. Mimwe mienzaniso yePolization Splitters inoratidzwa mumufananidzo 3 Yechipiri ndeye nyore kutungamira kaviri. Chimiro chegirefincence yeiyo silicon waya wire waveguide Yechitatu ndeye grating coupler, umo iyo fiber yakaiswa pakona kuitira kuti Te te mwenje yakaiswa pamwe chete mune imwe nhungamiro uye tm zvakazara mwenje wakabatanidzwa mune imwe. Yechina chisimbiso chevhu maviri Fiber modes ane minda yemagetsi iri perpendicular kune iyo nzira yeWesguide Kupararira kwakabatanidzwa kune inoenderana mesguide. Iyo fiber inogona kusungirirwa uye yakabatanidzwa kune maviri waveguides, kana perpendicular kune iyo nzvimbo uye yakabatanidzwa kune ina twoblguides. Mhedzisiro yakawedzerwa yevaviri-vadimikira grating ndeyekuti ivo vanoita kunge polated rotators, zvichireva kuti mwenje yese iri pane iyo chip
Mufananidzo 3: Multiple Polarization Splitters.
