YeSilicon-based optoelectronics, silicon Photodetectors

PhotodetectorsChinja zviratidzo zvechiedza muzvikwata zvemagetsi, uye seyakagadziriswa yedatha yedata inoenderera mberi nekuvandudza Chinyorwa ichi chinopa kutarisisa kweyakagadzirwa yepamusoro-simpined fototectors, nekusimbisa pane silicon yakavakirwa Germium (ge kana si Photodedector)Silicon Photodetectorsyekudyidzana optoelectronilogy.

Germerum ndeyekukwezva kwezvinhu zviri pedyo nekuvhenekerwa kwepasirivha pane silicon mapuratifomu nekuti inoenderana neCMOS maitiro uye ine yakasimba zvakanyanya kuyamwisa ku telecommunation wavelengths. Iyo inowanzoitika GE / SI Photodesetector Chimiro chePini Diode, umo iyo Instrinsic Germanium yakasungirirwa pakati peP-mhando uye n-mhando matunhu.

Chishandiso Chimiro Mufananidzo 1 unoratidza yakajairwa vertical pin kanaSi PhotomdetectorChimiro:

Zvimiro zvakakosha zvinosanganisira: Germany inobvisa denderedzwa rakura pane silicon substrate; Yaishandiswa kuunganidza p uye n yekubatanidza yevatakuri; Waveguide coupling yekunyatso bvuma.

Epitaxial kukura: Kukura Mhando yepamusoro yeGermium paSilicon inonetsa nekuda kwe4,2% lattice mismatch pakati pezvisikwa zviviri. A maviri-nhanho kukura maitiro anowanzoshandiswa: Tembiricha yakadzika (300-400 ° C) Buffer Layer Kukura uye Kupisa Kwakadzika (pamusoro pe600 ° C) kuiswa kweGermany. Iyi nzira inobatsira kudzora kuturika dislocations inokonzerwa ne lattice mismatches. Kutumira-kukura kunowedzera pa800-900 ° C.00 Kuenderera mberi kunodzora kuturika kwekuratidzira kusvika pagumi ^ 7 cm ^-cm ^2. Maitiro ekuita: Iyo Yakanyanya Yekupedzisira GE / SI PIN PhotoDetector inogona kuzadzisa: Kupindurwa,> 0.8a / w pana 1550 NM; Bandwidth,> 60 GHZ; Rima razvino, <1 μA at -1 v bias.

Kubatanidzwa neSilicon-based optoelectronics mapuratifomu

Kubatanidzwa kweYakakwira-Speed ​​PhotodectorsneSilicon-based optoelectronics mapepa anogonesa Advanced Optical Transcerives uye InterConnect. Nzira mbiri dzehunyanzvi hwekubatanidza dzinotevera: Front-Prexxpration yekubatanidza (ipo pikicha) Kumashure-kupera kubatanidza (bheori). Photodetectors inogadzirwa pamusoro pesimbi kuti udzivise kupindira neCMOS, asi inogumira kudzikisa kudziya tembiricha.

Mufananidzo 2: Kutevedzera uye Bandwidth yeakakwira-kumhanya ge / si Photodetector

Data Center application

Yakakwira-kumhanya Photodecetectors chikamu chakakosha mune inotevera chizvarwa che data cent centreconnection. Main application anosanganisira: Optical transceriver: 100G, 400g uye yakakwira mitengo, uchishandisa PAM-4 modulation; AYakakwira Bandwidth Photodetector(> 50 GHZ) inodiwa.

Silicon-based Optoelectrated Circrated Circuit: Monolitiki yekubatanidza ye detector neModulator uye zvimwe zvikamu; Compact, yakakwirira-perform yekuita injini.

Akagovera Architecture: Optical Interconnection pakati peKupa Computing, kuchengetedza, uye kuchengetedza; Kutyaira kudiwa kwesimba-inoshanda, yakakwirira-bandwidth photodetectors.

Ramangwana Outlook

Iyo yemberi yekudyidzana optoelectronic yakakwirira-mhanyisa mafotoDECECECETS icharatidza zvinotevera maitiro:

Yakakwira data mitengo: kutyaira kukura kwe 800g uye 1.6t kutengeserana; Photodetectors neBandwidths yakakura kupfuura 100 GHz inodiwa.

Kuvandudzwa kwekubatanidza: Imwe chip chip yekubatanidzwa kweIII-V zvinhu uye silicon; Advanced 3D Kubatanidza Tekinoroji.

Zvitsva Zvitsva: Kuongorora zvinhu zviviri-zviyero (senge grapheene) kwekusavimbika kwechiedza; Boka rutsva IV Alloy yekuwedzera wavelength yekuvhara.

Zvinoshandiswa Zvekubuda: Lidar uye kumwe kuseka kwekushandisa kuri kutyaira kusimudzira kweAPD; Microwave Photon application inoda yakakwira mutsara mafoto.

Yakakwirira-yekumhanyisa Photodecetectors, kunyanya ge kana si Photodecetectors, vava mutyairi akakosha weSilicon-based optoelectronics uye anotevera nyaya yekutaurirana. Kuenderera mberi kufambira mberi mumidziyo, mudziyo wekugadzira, uye tekinoroji yekubatanidza zvakakosha kusangana neyekukura bandwidth inodiwa yedzinza re data nzvimbo uye telecommunication network. Sezvo munda unoramba uchingoshanduka, tinogona kutarisira kuona mapikicha ane bandwidth bandwidth, ruzha rwezasi, uye kusanzwisisika kwemasevha nematunhu emagetsi uye emagetsi.
