Ngā pūoko whakaahua OFC2024

I tēnei rā, kia tirohia te OFC2024nga kaitirotiro whakaahua, ko te nuinga kei roto ko te GeSi PD/APD, te InP SOA-PD, me te UTC-PD.

1. Ka kitea e te UCDAVIS he Fabry-Perot kore-taurite, he 1315.5nm te kaha o te oro.pūoko whakaahuahe iti rawa te kaha, e kiia ana ko te 0.08fF. Ina ko te pānga he -1V (-2V), ko te iahiko pōuri he 0.72 nA (3.40 nA), ā, ko te tere urupare he 0.93a /W (0.96a /W). Ko te mana whatu kua kōtui he 2 mW (3 mW). Ka taea e ia te tautoko i ngā whakamātautau raraunga tere-teitei 38 GHz.
E whakaatu ana te hoahoa e whai ake nei i te hanganga o te AFP PD, he mea hanga mai i tētahi arataki ngaru e honoa ana ki te Ge-on-Pūoko whakaahua Sime te arataki ngaru SOI-Ge o mua e tutuki ana i te hononga taurite aratau > 90% me te whakaata o te <10%. Ko te muri he whakaata Bragg tohatoha (DBR) me te whakaata o te >95%. Mā te hoahoa kōhao kua arotauhia (te āhua taurite wāhanga hoki-hoki), ka taea te whakakore i te whakaata me te tuku o te resonator AFP, ka hua ake te mimiti o te pūoko Ge ki te tata ki te 100%. I runga i te whānui 20nm katoa o te roangaru pokapū, R+T <2% (-17 dB). Ko te whānui Ge he 0.6µm, ā, ko te kaha e kiia ana he 0.08fF.

2, i hangaia e te Whare Wānanga Pūtaiao me te Hangarau o Huazhong he germanium siliconte pūoro whakaahua horonga, whānui whānui >67 GHz, whakanui >6.6. Ko te SACMPūoko whakaahua APDKo te hanganga o te hononga pipin whakawhiti kua hangaia ki runga i te tūāpapa whatu silicon. Ko te germanium ā-roto (i-Ge) me te silicon ā-roto (i-Si) e mahi ana hei paparanga mimiti mārama me te paparanga takirua irahiko. Ko te rohe i-Ge me te roa o te 14µm e kī ana he pai te mimiti mārama i te 1550nm. Ko ngā rohe i-Ge me i-Si iti he pai ki te whakanui ake i te kiato o te iahiko whakaahua me te whakawhānui i te whānui o te whānui i raro i te ngaohiko whakahāngai teitei. I inehia te mahere kanohi APD i te -10.6 V. Me te mana whatu whakauru o te -14 dBm, ko te mahere kanohi o ngā tohu OOK 50 Gb/s me te 64 Gb/s e whakaaturia ana i raro nei, ā, ko te SNR i inehia ko te 17.8 me te 13.2 dB.

3. Kei roto i ngā whakaurunga raina whakamātautau IHP 8-inihi BiCMOS he germaniumPūoko whakaahua PDme te whānui o te parirau tata ki te 100 nm, ka taea te whakaputa i te papa hiko teitei rawa atu me te wā poto rawa o te nekehanga o te kaikawe whakaahua. Ko te whānui o te OE o Ge PD he 265 GHz@2V@1.0mA iahiko whakaahua DC. Kei raro nei te rere o te tukanga. Ko te āhuatanga nui ko te whakarērea o te whakaurunga katote SI tuku iho, ā, ka whakamahia te kaupapa whakairo tipu hei karo i te awe o te whakaurunga katote ki te germanium. Ko te iahiko pouri he 100nA,R = 0.45A /W.
4, e whakaatu ana a HHI i te InP SOA-PD, kei roto ko te SSC, MQW-SOA me te taputapu whakaahua tere-teitei. Mō te roopu-O. Ko te urupare a te PD he 0.57 A/W me te iti iho i te 1 dB PDL, ko te urupare a te SOA-PD he 24 A/W me te iti iho i te 1 dB PDL. Ko te whānui o te roa o te hononga o ngā mea e rua he ~60GHz, ā, ko te rerekētanga o te 1 GHz ka taea te kī ko te auau oro o te SOA. Kāore i kitea he pānga tauira i roto i te ahua kanohi tuturu. Ka whakaitihia e te SOA-PD te mana whatu e hiahiatia ana mā te 13 dB i te 56 GBaud.

5. Ka whakatinanahia e te ETH te GaInAsSb/InP UTC-PD kua whakapaitia ki te Momo II, me te whānui o te 60GHz @ kore-pānga me te mana putanga teitei o te -11 DBM i te 100GHz. He haere tonu o ngā hua o mua, mā te whakamahi i ngā āheinga kawe irahiko whakarei ake a GaInAsSb. I roto i tēnei pepa, ko ngā paparanga mimiti kua arotauhia ko te GaInAsSb kua tino tāpirihia o te 100 nm me te GaInAsSb kāore i tāpirihia o te 20 nm. Ka āwhina te paparanga NID ki te whakapai ake i te urupare whānui, ā, ka āwhina hoki ki te whakaiti i te kaha whānui o te taputapu me te whakapai ake i te whānui. Ko te whānui o te 64µm2 UTC-PD he whānui kore-pānga o te 60 GHz, he mana putanga o te -11 dBm i te 100 GHz, me te iahiko mātotoru o te 5.5 mA. I te pānga whakamuri o te 3 V, ka piki te whānui ki te 110 GHz.

6. I whakatūria e Innolight te tauira urupare auau o te taputapu whakaahua silicon germanium i runga i te whakaaro nui ki te tāpiritanga o te taputapu, te tohatoha o te mara hiko me te wā whakawhiti kaikawe whakaahua. Nā te hiahia mō te mana whakauru nui me te whānui o te whānui i roto i te maha o ngā tono, ka heke te whānui o te whānui i te mana whakauru nui, ko te mahi pai ko te whakaiti i te kukū kaikawe i roto i te germanium mā te hoahoa hanganga.

7, I hangaia e Te Whare Wānanga o Tsinghua ētahi momo UTC-PD e toru, (1) te hanganga paparanga nekeneke takirua (DDL) 100GHz me te mana whakakī teitei UTC-PD, (2) te hanganga paparanga nekeneke takirua (DCL) 100GHz me te urupare teitei UTC-PD, (3) te whānuitanga 230 GHZ MUTC-PD me te mana whakakī teitei. Mō ngā āhuatanga tono rerekē, ka whai hua pea te mana whakakī teitei, te whānuitanga teitei me te urupare teitei i te heke mai ina uru atu ki te ao 200G.
