I tenei ra ka titiro tatou ki OFC2024nga kaitirotiro whakaahua, kei roto ko GeSi PD/APD, InP SOA-PD, me UTC-PD.
1. Ka mohio a UCDAVIS he ngoikore te resonant 1315.5nm kore-hangarite Fabry-Perotkaitirotiro whakaahuahe iti rawa te punga, e kiia ana ko te 0.08fF. Ina ko te rītaha -1V (-2V), ko te 0.72 nA (3.40 nA) te au pouri, me te 0.93a /W (0.96a /W) te tere whakautu. Ko te mana whatu kukū he 2 mW (3 mW). Ka taea e ia te tautoko i nga whakamatautau raraunga tere-tere 38 GHz.
Ko te hoahoa e whai ake nei e whakaatu ana i te hanganga o te AFP PD, kei roto he kaiarahi ngaru kua honoa a Ge-on-Ko te kaitirotiro whakaahuame te kaiarahi ngaru SOI-Ge o mua ka eke ki te > 90% te honohono aratau me te whakaata o te <10%. Ko te tuara he whakaata Bragg kua tohatohahia (DBR) me te whakaata o> 95%. Na roto i te hoahoatanga o te kohao kua tino pai (te ahua o te wa e rite ana ki nga haerenga a tawhio noa), ka taea te whakakore i te whakaata me te tuku o te resonator AFP, na te mea ka tata ki te 100%. I runga i te 20nm bandwidth katoa o te roangaru pokapū, R+T <2% (-17 dB). Ko te whanui Ge he 0.6µm me te whakaaro ko te puritanga he 0.08fF.
2, Huazhong University o Pūtaiao me Hangarau hanga he germanium siliconphotodiode horo, hōkaiipurangi >67 GHz, whiwhi >6.6. Ko te SACMAPD photo detectorKo te hanganga o te hononga paipa whakawhiti he mea hanga ki runga i te papaaa mata kirika. Ko te germanium intrinsic (i-Ge) me te silicon intrinsic (i-Si) ka noho hei paparanga momi marama me te paparanga rearua irahiko. Ko te rohe i-Ge me te roa o te 14µm e whakamana ana i te urunga marama ki te 1550nm. Ko nga rohe iti i-Ge me i-Si e pai ana ki te whakanui ake i te kiato o te photocurrent me te whakawhānui i te bandwidth i raro i te ngaohiko teitei. I inehia te mahere kanohi APD ki te -10.6 V. Ma te kaha o te mata whakauru -14 dBm, ko te mahere kanohi o nga tohu 50 Gb/s me te 64 Gb/s OOK e whakaatuhia ana i raro nei, a ko te SNR ine ko 17.8 me te 13.2 dB , ia.
3. IHP 8-inihi BiCMOS raina pairati e whakaatu ana i te germaniumPD photo detectorhe 100 nm te whanui o te kemu, ka taea te whakaputa i te papa hiko teitei me te wa poto rawa atu o te kaikawe whakaahua. Kei a Ge PD te bandwidth OE o 265 GHz@2V@ 1.0mA DC photocurrent. Ko te rere o te tukanga e whakaatuhia ana i raro nei. Ko te mea nui rawa atu ko te tukunga o te whakaurunga katote whakaurunga o te SI tuku iho kua whakarerea, a ka whakamahia te kaupapa tarai tipu hei karo i te awe o te whakaurunga katote ki runga i te germanium. Ko te au pouri ko 100nA,R = 0.45A /W.
4, HHI e whakaatu ana i te InP SOA-PD, kei roto ko SSC, MQW-SOA me te kaitirotiro whakaahua tere. Mo te roopu O. Ko te PD he A te urupare o 0.57 A / W me te iti iho i te 1 dB PDL, i te SOA-PD he urupare o 24 A / W me te iti iho i te 1 dB PDL. Ko te bandwidth o nga mea e rua ko ~ 60GHz, a ko te rereketanga o te 1 GHz ka taea te tohu ki te resonance frequency o te SOA. Karekau he awe tauira i kitea i te ahua o te kanohi. Ka whakaitihia e te SOA-PD te mana whatu e hiahiatia ana mo te 13 dB i te 56 GBaud.
5. Ka whakatinanahia e te ETH te Momo II te whakapai ake i te GaInAsSb/InP UTC-PD, me te bandwidth o 60GHz@ zero bias me te mana whakaputa teitei o -11 DBM i 100GHz. Te haere tonu o nga hua o mua, ma te whakamahi i nga kaha kawe irahiko a GaInAsSb. I roto i tenei pepa, kei roto i nga papa whakaurunga pai te GaInAsSb kua 100 nm me te GaInAsSb kore e 20 nm. Ka awhina te paparanga NID ki te whakapai ake i te urupare katoa me te awhina hoki ki te whakaheke i te kaha o te taputapu me te whakapai ake i te bandwidth. Ko te 64µm2 UTC-PD he 60 GHz kore-bias bandwidth, he mana whakaputa -11 dBm i te 100 GHz, me te naianei waiwai o 5.5 mA. I te rītaha whakamuri o te 3 V, ka piki te bandwidth ki te 110 GHz.
6. I whakatauhia e Innolight te tauira whakautu auau o te kairapu whakaahua germanium silicon i runga i te tino whakaaro ki te doping taputapu, te tohatoha mara hiko me te wa whakawhiti kaikawe whakaahua. Na te hiahia mo te mana whakauru nui me te bandwidth teitei i roto i te maha o nga tono, ko te whakaurunga mana optical nui ka whakaheke i te bandwidth, ko te mahi pai ko te whakaheke i te kukū kawe i roto i te germanium ma te hoahoa hanganga.
7, I hangaia e te Whare Wananga o Tsinghua nga momo momo UTC-PD e toru, (1) 100GHz paparanga maru rua (DDL) te hanganga me te kaha o te kaha UTC-PD, (2) 100GHz te paparanga taarua rua (DCL) me te whakautu nui UTC-PD , (3) 230 GHZ bandwidth MUTC-PD me te kaha o te kaha o te kaha, Mo nga ahuatanga tono rereke, ka whai hua te kaha o te kaha o te kaha, te teitei me te whakautu nui i te wa kei te heke mai ka uru atu ki te waa 200G.
