Ngā putanga hou i roto iKaiwhakarerekē LiNbO3
Nō nā tata nei, kua tukuna e ngā kairangahau Hainamana tētahi mana pupuri matua mō te hangarau raka auau taiaho PDH. He pūnaha raka auau taiaho PDH e hangai ana ki te SOA kore-raina (Semiconductor Optical Amplifier) hei whakaputa i ngā taha taha. Ko te whāinga o tēnei mana pupuri he aro ki ētahi āhuatanga matua o te pūnaha raka auau taiaho PDH (Pound-Drever-Hall) tuku iho nā te whakamahinga o te lithium niobate (LiNbO3 modulator) me ētahi atu.kaiwhakarerekē hiko-whatu.
1. Ko ngā raruraru matua o te otinga tuku iho ko:
1.1 Te utu nui me te hanganga uaua: Ko ngā whakarerekētanga hiko-whatu tuku iho e hiahia ana ki ngā ara iahiko taraiwa RF me ngā ara iahiko whakahāngai.
1.2 Te aro ki te taiao: Te aro ki ngā huringa pāmahana me te ahotea, ka ngāwari ki ngā āhuatanga rerekē o te pōraruraru.
1.3 Pānga whakarerekētanga whānui toenga (RAM): Ka puta te piko DC o te tohu hapa i tēnei, ka neke haere te pūwāhi raka taiaho, ā, ka pā kino ki te pumau mō te wā roa o te pūnaha.
2. Ko te otinga auaha i whakatakotoria e te rōpū rangahau ko:
Whakarērea rawatia te whakarerekētanga hiko-whatu tuku iho, ka whakamahi i tētahi hoahoa mahi tahi owhakakaha whatu haurua-haurua(whakakaha SOA) i honoa ki ngā whakawhiti auau acousto-whatu ara-rua. Ko te kaupapa mahi motuhake ko: Whai muri i te wehewehe i te taiaho purapura, ka nekehia te auau e ngā whakawhiti auau acousto-whatu ara-rua e rua, ka puta he rerekētanga auau, kātahi ka honoa ngā ara mārama e rua ka werohia ki roto i te whakakaha SOA i te āhua kukū whiwhi. Mā te whakamahi i ngā pānga kore-raina pēnei i te whakaranu ngaru-whā (FWM) o teWhakakaha SOA, ka whakaputahia paitia ngā tohu maha-taha e hiahiatia ana mō te raka auau PDH.
3. Ka kawea mai e tēnei hangarau ngā painga mahi whakararuraru e whai ake nei:
3.1 Te wikitoria i te raruraru RAM me te whakatutuki i te pumau roa-tino-tiketike: Ka whakauruhia e te taputapu whakakaha SOA (i roto i te kete pūrerehua te nuinga) te whakahaere pāmahana, ā, he tino kore e pāngia e ngā raruraru taiao, ka karohia te raruraru RAM mai i te tikanga ā-tinana, ā, ka tutuki te tika o te raka roa o te kōhao he pai ake i te 5×10⁻¹¹/rā.
3.2 Te taurite tika o ngā whitiki taha, he whakapainga nui i te ōwehenga tohu-ki-haruru: Mā te whakahaere motuhake i te nui o te nekehanga o ngā whakawhiti auau acousto-whatu rua-ara (100 MHz – 200 MHz) e ngā oscillator e rua e whakahaerehia ana e te ngaohiko (VCO), ka taea te taurite pai i te wā auau o ngā whitiki taha kua hangaia ki te awhe hiato kore utu (FSR) o te kōhao tohutoro, ā, ka tino whakapai ake i te ōwehenga tohu-ki-haruru o te tohu hapa.
3.3 Te whakaiti i te utu me te whakapai ake i te whai huatanga, e whai hua ana ki te whakaitiiti i te pūnaha: Ki te kore te modulator hiko-whatu utu nui me ngā ara iahiko uaua, ko te kaha hiko SOA anake e hiahiatia ana e te whakakaha whatu, kia iti ake ai te pūnaha katoa, kia iti ake ai te utu, ā, kia pai ake ai mō ngā tono mara o waho taiaho tino tika me te whakaitiiti.
3.4 Ko ngā tūmanako whānui mō te whakamahinga me te hiahia o te mākete mō tēnei hangarau ko:
Ngā karaka whatu mō te wāhi me te waka: Ko ōna āhuatanga ārai-whakararuraru e tino tutuki ana i ngā whakaritenga o te ao rererangi me ngā waka kore tangata.
Ngā mita taumaha kuantum me ngā mita whakawhiti ngota matao: Ka taea te whakamahi mō te tūhuratanga whenua tino tika me te whakatere i raro i te wai.
Te pūoko muka teitei me te radar huinga ā-wāhanga honohono (LiDAR): Ka taea te whakarato i ngā pūtake mārama tohutoro whānui-rārangi tino whaiti, kāore he rerenga.
I raro i te ia o te hurihanga matūriki tuarua o te ao me te whakaitiiti i ngā pūoko matūriki, kua tino piki ake te hiahia o te mākete mō ngā kōwae waeine taiaho ka taea te whakahaere motuhake, he iti te utu, he pumau hoki, ā, he tika te tutuki a tēnei hangarau patent i tēnei ia o te mākete.
