Kev sib piv ntawm cov photonic sib xyaw ua ke cov khoom siv

Kev sib piv ntawm cov photonic sib xyaw ua ke cov khoom siv
Daim duab 1 qhia kev sib piv ntawm ob cov khoom siv ob, indium phosphorus (inp) thiab silicon (si). Qhov tsis tshua muaj ntawm inresium ua inp ib qho khoom kim dua li si. Vim tias Silicon-based circuits koom nrog kev loj hlob tsawg dua, cov txiaj ntsig ntawm cov khoom sib txuas ua silicon feem ntau yog siab dua li ntawm INP circuits. Hauv Silicon-based circuits, germanium (ge), uas feem ntau tsuas yog siv nyob rau hauvPhotodetector(Lub teeb ntes), xav kom muaj kev loj hlob hauv kev loj hlob, thaum nyob hauv cov iSP tshuab, txawm passguides yuav tsum npaj kom txhij los ntawm kev loj hlob tuaj. Txoj kev loj hlob tuaj yeem ua rau muaj kev cuam tshuam ntau dua li ib qho kev loj hlob ua ke, xws li los ntawm kev tawm suab. Inp WaveGuides tau muaj siab refrate index tsis sib xws hauv ob translicon-raws li cov khoom siv sib txawv kom ua tiav cov radii thiab lwm yam kev cog qoob loo ntau dua. Ingaasp muaj cov hlua khi ncaj qha, thaum SI thiab GE tsis. Raws li qhov tshwm sim, cov khoom siv hluav taws xob yog qhov zoo dua hauv cov qib ntawm laser kev ua haujlwm. Cov oxides intrinsic ntawm cov tshuab hauv Inp tsis ruaj khov thiab khov raws li cov oxides intrinsic ntawm Si, silicon dioxide (sio2). Silicon yog cov khoom muaj zog dua li INP, tso cai rau cov wafer loj dua thiab siv 300 mm (tsis ntev los tau txhim kho mus rau 4,5) piv rau 75 mm hauv inp. Tus saibmodulatorsFeem ntau yog nyob ntawm Quantum-kaw Stark Cov nyhuv, uas yog qhov ntsuas kub-rhiab vim yog kev tawm suab band los ntawm kub. Hauv kev sib piv, kev vam khom kub ntawm Silicon-based modulators yog qhov tsawg heev.

Silicon photonics technology yog feem ntau suav tsuas yog haum rau tus nqi tsawg, luv luv, muaj ntau dua 1 lab daim ib xyoos). Qhov no yog vim tias nws tau lees tias muaj ntau yam ntawm wafer muaj peev xwm yuav tsum tau kis daim npog ntsej muag thiab cov nqi txhim kho, thiabsilicon photonics tshuabMuaj qhov ua tau tseem ceeb tsis zoo nyob hauv nroog-rau-nroog cheeb tsam thiab lub nroog cov khoom lag luam ntev. Hauv kev muaj tiag, txawm li cas los xij, qhov rov qab yog qhov tseeb. Nyob rau hauv tus nqi qis, luv-ntau, high-cam-adcy daim ntawv thov, ntsug kab noj hniav nto-emitting ntas-emitting Laser (VCELS) thiabDirect-Modulated Laser (Dml laser): Qhia ncaj qha laser pleev ib qho kev sib tw loj, thiab qhov tsis muaj zog ntawm cov roj ntsha uas tsis muaj peev xwm ua tau yooj yim ua lasers tau dhau los ua qhov tsis zoo. Hauv kev sib piv, hauv cov ntawv sau, ntev-ntev, vim yog qhov kev nyiam ua ke rau kev sib koom ua ke (DSP) ua ke (DSP) ua ke) Ntxiv rau, cov kev kuaj pom kev siv tshuab tuaj yeem ua rau qhov tsis txaus ntseeg ntawm silicon photonics technology yog ntau me dua li cov oscillator photocillator. Nyob rau tib lub sijhawm, nws kuj yog qhov tsis ncaj ncees los xav tias muaj kev nyab xeeb ntau los npog npog ntsej muag thiab kev loj hlob ntau tshaj li cov neeg sib txawv tshaj plaws (cmos), Yog li cov qhov ntswg uas yuav tsum muaj thiab ntau lawm khiav yog pheej yig.
