Whakauruhia te modulator Mach-Zehnder photonic siliconKaiwhakarerekētanga MZM
Ko te pūwhakatikatika Mach-Zehnder te wāhanga tino nui i te pito tuku i roto i ngā kōwae photonic silicon 400G/800G. I tēnei wā, e rua ngā momo pūwhakatikatika i te pito tuku o ngā kōwae photonic silicon i hangaia nuitia: Ko tētahi momo ko te pūwhakatikatika PAM4 i runga i te aratau mahi kotahi-hongere 100Gbps, e tutuki ana i te tuku raraunga 800Gbps mā te huarahi whakarara 4-hongere / 8-hongere, ā, e whakamahia ana i roto i ngā pokapū raraunga me ngā GPU. Ko te tikanga, kāore e tika kia tawhiti atu i te pūwhakatikatika Mach-Zender silicon photonics 200Gbps kotahi-hongere ka whakataetae ki te EML i muri i te whakaputanga nui i te 100Gbps. Ko te momo tuarua ko teKaiwhakarerekē IQe whakamahia ana i roto i te whakawhitiwhiti whatu arorau tawhiti. Ko te totohu arorau kua whakahuatia i tēnei wā e pā ana ki te tawhiti tuku o ngā kōwae whatu mai i ngā mano kiromita i roto i te whatunga tuara o te tāone nui ki ngā kōwae whatu ZR mai i te 80 ki te 120 kiromita, tae atu ki ngā kōwae whatu LR mai i te 10 kiromita a muri ake nei.
Te kaupapa o te tere terengā kaiwhakarerekētanga siliconka taea te wehewehe kia rua ngā wāhanga: te whatu me te hiko.
Wāhanga whatu: Ko te kaupapa matua he ine whakawhiti Mach-Zehnder. Ka haere te hihi mārama mā roto i te wehewehe hihi 50-50 ka huri hei hihi mārama e rua me te kaha ōrite, ka tukuna tonutia i roto i ngā ringa e rua o te modulator. Mā te whakahaere ā-wāhanga i runga i tētahi o ngā ringa (arā, ka whakarerekētia te taupū whakaata o te silicon e te whakamahana hei whakarerekē i te tere horapa o tētahi ringa), ka mahia te huinga hihi whakamutunga i te putanga o ngā ringa e rua. Ka taea te whakatutuki i te roa ā-wāhanga whakararuraru (kei hea ngā tihi o ngā ringa e rua e tae atu ana i te wā kotahi) me te whakakorenga whakararuraru (kei hea te rerekētanga ā-wāhanga he 90°, ā, kei te ritenga atu o ngā awaawa ngā tihi) mā te whakararuraru, mā te whakarerekē i te kaha o te mārama (ka taea te mārama ko te 1 me te 0 i roto i ngā tohu matihiko). He māramatanga ngāwari tēnei, ā, he tikanga whakahaere hoki mō te pūwāhi mahi i roto i ngā mahi mahi. Hei tauira, i roto i te whakawhitiwhiti raraunga, ka mahi mātou i tētahi pūwāhi 3dB iti iho i te tihi, ā, i roto i te whakawhitiwhiti mārama, ka mahi mātou i tētahi wāhi mārama kāore he pūwāhi. Heoi, he roa rawa te wā e pau ana ki tēnei tikanga whakahaere i te rerekētanga ā-wāhanga mā te whakamahana me te tohatoha wera hei whakahaere i te tohu putanga, ā, kāore e taea te whakatutuki i tā tātou whakaritenga mō te tuku 100Gpbs ia hekona. Nō reira, me kimi he huarahi hei whakatutuki i te tere tere o te whakarerekētanga.
Ko te wāhanga hiko te nuinga o te wāhanga hononga PN e hiahia ana ki te whakarerekē i te taupū whakaata i te auau teitei, me te hanganga hiko ngaru haere e rite ana ki te tere o te tohu hiko me te tohu whatu. Ko te kaupapa o te whakarerekē i te taupū whakaata ko te pānga marara plasma, e mōhiotia ana ko te pānga marara kawe kore utu. E pā ana ki te pānga ā-tinana ina whakarerekētia te kukū o ngā kawe kore utu i roto i te rauemi haurua-waenga, ka rerekē anō hoki ngā wāhanga tūturu me ngā wāhanga pohewa o te taupū whakaata o te rauemi. Ina piki ake te kukū o ngā kawe i roto i ngā rauemi haurua-waenga, ka piki ake te tauwehenga mimiti o te rauemi i te mea ka heke te wāhanga tūturu o te tauwehenga whakaata. Waihoki, ina heke ngā kawe i roto i ngā rauemi haurua-waenga, ka heke te tauwehenga mimiti i te mea ka piki ake te wāhanga tūturu o te tauwehenga whakaata. Me tēnei pānga, i roto i ngā tono mahi, ka taea te whakatutuki i te whakatikatika o ngā tohu auau-tiketike mā te whakahaere i te maha o ngā kawe i roto i te arataki ngaru tuku. I te mutunga, ka puta ngā tohu 0 me te 1 i te tūranga putanga, ka utaina ngā tohu hiko tere-tiketike ki runga i te kaha o te māramatanga. Ko te huarahi ki te whakatutuki i tēnei ko te hononga PN. He iti noa iho ngā kaikawe kore utu o te silicon parakore, ā, kāore e ranea te panonitanga o te rahinga hei whakatutuki i te panonitanga o te taupū whakaata. Nō reira, me whakanui ake te turanga kaikawe i roto i te arataki ngaru tuku mā te tāpiri i te silicon kia tutuki ai te panonitanga o te taupū whakaata, kia eke ai ki te tere whakarerekētanga teitei ake.
