Silicon Photonics Active Element

Silicon Photonics Active Element

Photonics inoshanda zvikamu zvinoratidza zvakananga kune zvakaringana zvakagadzirirwa masimba ekudyidzana pakati pechiedza nepfungwa. Chinhu chakajairika chinoshanda chezvinyorwa zvemhando yepamusoro. Zvese zvazvino silicon-basedOptical Modulatorszvakavakirwa pane plasma yemahara yekutakura maitiro. Kuchinja huwandu hwemagetsi emagetsi uye maburi mune zvinyorwa zveSilicon nekugadzirisa, maitiro ezvematongerwo enyika. Zvichienzaniswa nemagetsi, maburi anokonzera huwandu hwakakura hweiyo chaiyo uye yekufungidzira kudzora shanduko, kureva kuti, vanogona kuburitsa shanduko yakakura yekuchinja kwakapihwa kwekuchinja, zvakadaro mukatiMach-zehod modulatoruye mhete dzinofamba-famba, rinowanzo sarudza kushandisa maburi kuti vagadzirePhose Modulators.

VariousSilicon (si) modulatorMhando dzinoratidzwa mumufananidzo 10a. Mune mutakuri jekiseni jekiseni, chiedza chiri mune intrinsic silicon mukati meiyo yakafara kwazvo pini junction, uye maelectrons nemakomba akaiswa. Nekudaro, manyoro akadaro anononoka, kazhinji aine bandwidth ye 500 MHz, nekuti magetsi emahara anotora nguva yakareba kuti atsvage. Naizvozvo, ichi chimiro chinowanzoshandiswa seyakajairwa optical quatuator (voa) pane modulator. Mune mutakuri wekutakurisa Modulator, chikamu chechiedza chiri mune yakamanikana pn junction, uye inobata upamhi hwePN Junction inoshandurwa nemunda wakashandiswa emagetsi. Iyi modlator inogona kushanda pakumhanya yakawandisa ye50GB / s, asi ine yakakwirira yekumashure kurasikirwa. Iyo yakajairika VPil ndeye 2 v-cm. Iyo nzombe yerudzi rwemasikati Inobvumira imwe yekutakura yekuwedzera pamwe neyekutakura inodonha, ichibvumira idiki diki yeanenge 0,2 v-cm, asi ine kusagadzikana kwekurasikirwa kwepamusoro uye yepamusoro yekuwedzera pachiyero chekureba. Mukuwedzera, pane sige yemagetsi yekufambisa modulators yakavakirwa paSige (Silicon Germany Alloy) Band Edge Modell. Uye zvakare, kune maGriphene modulators anovimba neGriphene kuti ichinje pakati pekutora simbi uye inoongorora pachena. Izvi zvinoratidza zvakasiyana siyana zvekushandisa zvemakirowa akasiyana kuti uwane yakakwira-kumhanya, kurasikirwa-kurasikirwa chiratidzo chiratidzo chekusarudza chiratidzo.

Akati wandei silicon-based magetsi anoongorora anoonekwa mumufananidzo 10b. Iyo yekubvisa zvinhu ndeye Germany (GE). Ge inokwanisa kutora mwenje paWavelengths pasi kusvika pamicons. Inoratidzwa kuruboshwe ndicho chinhu chakanyanya kubatikana chakabudirira pini chimiro nhasi. Iyo inoumbwa neP-mhando yakarongedzwa silicon pane iyo ge inokura. GE uye SI ine 4% LATTE MISTBatch, uye kuitira kuderedza dislocation, iyo yakaonda chikamu cheSIG yakatanga kukura sebuffer layer. N-Type Doping inoitwa pamusoro peiyo Ge Layer. Simbi-semiconductor-simbi (msm) Photodiode inoratidzwa pakati, uye APD (Avalanche Photodetector) inoratidzwa kurudyi. Dunhu reAvalache muApd riri muSi, iyo ine yakaderera ruzha chimiro ichienzaniswa neiyo Avalache Dunhu muboka III-V Elemental zvinhu.

Parizvino, hapana mhinduro dzine zviyero zviri pachena mukubatanidza Optical kuwana neSilicon photonics. Mufananidzo 11 unoratidza zvakati wandei zvisarudzo zvinosarudzwa zvakarongedzwa neshambadziro yegungano. Kuruboshwe kuruboshwe zviyero zvinosanganisira kushandiswa kweECitaxally Greepy Greepy (er) Girazi (er) yegirazi (er) Chikamu chinotevera chakatsemuka kuWafer Assembly, chinosanganisira nzombe uye organic bonding muIII-v Boka Rawana Dunhu. Chikamu chinotevera cheColums Chip-kuWerer Assembly, izvo zvinosanganisira kusimbisa iyo III-v yeboka chipinde mumusikirwo weiyo silicon wafer uye ipapo machining the waveguide chimiro. Kubatsira kweiyi yekutanga nhatu nzira ndeyekuti chishandiso chinogona kuve chakazara zvinoshanda muyedzo mukati mehomwe usati wadimburwa. Iyo chaiyo-yakanyanya kubvumirana chiken-to-to-to-t-chip gungano, kusanganisira yakananga kuyamwa yeSilicon Chips kune III-v Boka Chips, pamwe nekukasira kuburikidza lens uye grat clamers. Maitiro ekutengesa ekutengeserana ari kufamba kubva kurudyi kuruboshwe rwechati kune imwe nzvimbo yakabatanidzwa uye yakabatanidzwa mhinduro.

Mufananidzo 11: How Excal kuwana yakabatanidzwa mu silicon-based photonics. Sezvaunobva kubva kuruboshwe kurudyi, iyo yekugadzira yekuisa pfungwa zvishoma nezvishoma inodzokera kumashure mune maitiro.
