Kuenzanisa kwe phonic yakabatanidzwa dunhu redunhu system
Mufananidzo 1 unoratidza kuenzanisa kwezvirongwa zviviri zvekunyama, indium phosphorus (inp) uye silicon (si). Ragariro yenzvimbo inoita kuti inp ining yakadhura kupfuura Si. Nekuti matunhu eSilicon anosanganisira kushomeka kushoma epitaxal Epitaxial Ekukura, kubereka kwemasendimita-kwakadzivirirwa kazhinji kunowanzo kuve kwakakwirira kupfuura iwo wemasikati. MuSilicon-based Dunhu, Germium (GE), rinowanzo shandiswa mukatiPhotomdetector(mishonga yekuona), inoda kukura kwekukura, nepo mumasisitimu, kunyange passive waveguides inofanira kuve yakagadzirirwa nekukura kwe epitaxic. Epitaxial kukura kunowanzove nehuremu hwakanyanya hwekukura pane imwe yekunyora yekukura, yakadai kubva kune yakavanzika ingot. Inp Wachugides ane High Refractive Index Kupesana chete, nepo silicon-based waveguides ine midziyo yakakwira Ingaasp ine bhendi yakananga bhendi, nepo si uye ge usadaro. Semhedzisiro, inp yezvinhu masisitimu yakakwirira maererano neLaser kushanda kweLaser. Iyo intrinsic oxides ye inp system haina kunge yakagadzikana uye kusimba semhou dzepakati dzeSi, Silicon dioxide (Sio2). Silishon inzvimbo yakasimba kupfuura inf, ichibvumira kushandiswa kweiyo yakakura michero yemabhiza, kureva kubva 300 mm (munguva pfupi yekukwidziridzwa kune 450 mm) zvichienzaniswa 75 mm mu inp. Inpmodulatorskazhinji inotsamira pane huwandu-hwakavharirwa chimiro, chinova tembiricha-inotyisa nekuda kweBand kumucheto kufamba kwakakonzerwa nekushisa. Mukupesana, kutsamira kweshiri kweSilicon-based modulators idiki kwazvo.

Silicon photonics tekinoroji inowanzoonekwa seyakakodzera yakakodzera-mutengo wakaderera, ipfupi-huwandu, huwandu hwehuwandu (zvinopfuura mamirioni 1 zvimedu zvegore). Izvi zvinogamuchirwa kuti zvinogamuchirwa zvakanyanya kuti huwandu hukuru hwe waffer hunhu hunodiwa kuparadzira mask uye mari yekuvandudza, uye izvoSilicon Photonics Technologyine yakakosha maitiro ekuita mune yeguta-kune-guta matunhu uye refu-haul zvigadzirwa zvekushandisa. Muchokwadi, zvisinei, zvakapesana ichokwadi. Mune yakaderera-mutengo, pfupi-huwandu, yakakwirira-yezvikumbiro, vertical cavity pamusoro-inobvisa laser (vcsel) uyeDirect-yakasungirirwa laser (DML laser): zvakanyatso shanduka lases inokwikwidza kukwikwidza kwakakura, uye kushaya simba kwesimbi-based tekinoroji isingakwanise kunyatsobatanidza lasers rave kuita kwakakosha. Mukupesana, muMetro, kureba-kureba-kureba kwekuda kwekubatanidza silicon tekinoroji uye Dhijitari chiratidzo Pamusoro pezvo, tekinoroji yekuona inogona kuita kuti zvikanganiso zveSilicon phonical tekinoroji kune yakakura, sedambudziko iro riripo riripo rakawanda kupfuura renzvimbo yesalcular. Panguva imwecheteyo, zvakakanganisika kuti ufunge kuti huwandu hwakawanda hwekuvhara mask uye silish phototical tekinoroji iyo yakanyanya kuwanda mitezo yeiyo mitezo yezasi (
