Kushandiswa kwehuwandumicrowave photonics tekinoroji
Kusaona zvisina simba
Imwe yemanyorero ekuvimbisa kwazvo ehuwandu hwemicrowave tekinoroji tekinoroji ndeyekuonekwa kwakanyanya kushaya simba microwave / rf signals. Nekushandisa imwe chete phonton yekuona, aya masisitimu anotarisisa zvakanyanya pane nzira dzechinyakare. Semuenzaniso, vatsvagiri vakaratidza huwandu hwemicrowave photonic system iyo inogona kuona masaini seyakaderera se -112.8 DBM pasina chero yemagetsi emagetsi. Uku Ultra-yepamusoro sensitivity kunoita kuti ive yakakodzera kune ma application yakadai seyakadzika nzvimbo yekutaurirana.
Microwave PhotonicsSignal Processing
Quantum microwave mahotonics anogadzira zvakare yakakwira-bandwidth chiratidzo chekugadzirisa mabasa akadai seheti yekuchinja uye kusefa. Nekushandisa chinhu chinopararira chepamusoro uye kugadzirisa iyo wavelength yechiedza, vaongorori vakaratidza chokwadi chekuti Rf chikamu chinosvika kusvika ku8 GHZ RF kuseya bandwidths kumusoro kusvika ku8 GHZ. Zvakakosha, izvi zvinongedzo zvese zvinowanikwa uchishandisa 3 GHZ zvemagetsi, izvo zvinoratidza kuti kuita kunodarika tsika yechinyakare yebandwidth miganhu
Isina-yemuno frequency kusvika nguva mamepu
Kugona kumwe kukanganisika kwakaunzwa neQuentum Ekisimeni ndiko kubuda kweisina-yemuno frequency nenguva. Iyi nzira inogona mepu inogona kumhanyisa mbozha yekuenderera mberi-wave yakamwirwa single-Photon sosi kune imwe nguva domain kunzvimbo iri kure. Iyo sisitimu inoshandisa yakabatanidzwa phonar maviri mune iyo danda rimwe rinopfuura nepakati pefaira rekusvitsa uye imwe yacho inopfuura kuburikidza nechinhu chinopararira. Nekuda kweiyo nguva yekudzivirirwa kwemapikicha akanyorwa, maitiro ekusvitsa efaira akasungwa asiri-munharaunda kusvika kunguva domain.
Mufananidzo 1 unoratidza iyi pfungwa:
Iyi nzira inogona kuwana inochinjika spectral yekuyera pasina kunyengedza zvakananga iyo yakayerwa mwenje sosi.
Yakamanikidzwa Kupokana
Huwandumicrowave OpticalTekinoroji inopa zvakare nzira itsva yekumanikidza kunzwa kwemasaini yeBroadband. Kushandisa midziyo yekusagadzikana muhuwandu hwekuona, vatsvagiri vakaratidza huwandu hwehuwandu hwakamanikidzwa sisitimu inokwanisa kupora10 GHZ RFSpectra. Iyo sisitimu inoburitsa iyo RF chiratidzo kune iyo polarization mamiriro eiyo cohoter Photon. Single-Photon Kuona ipapo inopa chaiyo yakasarudzika chiyero matsaru matrix kune yakamanikidzwa yekunzwa. Nenzira iyi, chiratidzo chakaburitswa chinogona kudzoreredzwa kuYarnyquist Sampling Rate.
Quantum Key Kugoverwa
Pamusoro pekuwedzera kwechinyakare microwave photonic application. Vaongorori vakaratidzira subcarrier multiplex mostplum kiyi kugoverwa (scm-qkd) nekuwanda microwave photos supcarrier pane quatum kiyi kugoverwa (QKD) system. Izvi zvinobvumira akawanda akazvimirira quantum makiyi ekutapurirwa pamusoro peimwe wavelength yechiedza, nekudaro achiwedzera spectral kushanda.
Mufananidzo 2 unoratidza pfungwa uye kuedza kwekuedza kweiyo Dual-Carrier SCM-QKD system:
Kunyangwe huwandu hwemicrocave tekinoroji yeTekinari inovimbisa, kuchine mamwe matambudziko:
1. Kuganhurirwa chaiko-nguva kugona: Iyo iripo system inoda yakawanda yekuunganidza nguva yekuvandudza chiratidzo.
2.
3. Chinja kune chaiyo microwave waveform: mamwe matanho anodikanwa kushandura iyo yakagadziriswazve iyo Histograp inyonganiso inoshanda.
4. Chishandiso hunhu: Kuwedzera Kudzidza kwehunhu hwehuwandu hwehuwandu uye microwave photonic zvishandiso mumasangano akasanganiswa anodiwa.
5. Kubatanidza: Mazhinji masisitimu nhasi anoshandisa bulky discrete zvikamu.
Kugadzirisa izvi zvinonetsa uye kufambira mberi munda, nhamba yekuvimbisa ongororo yekutsvagisa ndeyekuti:
1. Kukudziridza nzira nyowani dzechokwadi-nguva chiratidzo chekugadzirisa uye kamwe chete kuona.
2. Ongorora zvikumbiro zvitsva zvinoshandisa zvakakwirira kunzwa, zvakadai sekuyera kwemvura microsphere.
3. Tevera kuzadzikiswa kwehuwandu hwakabatanidzwa uye ma elekitori kuderedza saizi uye kuoma.
4. Dzidza iyo yakawedzerwa mwenje-nyaya yekudyidzana mune yakabatanidzwa huwandu hwehuwandu hwemicrowave ma Photonic matunhu.
5. Chibatanidza huwandu hwemicrowar photon tekinoroji nedzimwe dzinobuda tekinoroji.
