Inqubekela phambili yocwaningo lwakamuva ku-modulator ye-sideband eyodwa
I-Rofea Optoelectronics izohola imakethe yomhlaba wonke ye-single sideband modulator. Njengomkhiqizi ohamba phambili emhlabeni we-electro-optic modulators, ama-SSB modulator e-Rofea Optoelectronics adunyiswa ngokusebenza kwawo okuphezulu kanye nokuguquguquka kwesicelo. Izinhlelo zokuxhumana ze-5G kanye ne-6G ezisanda kwethulwa zikhulise isidingo sama-modulator anesivinini esikhulu, kanti ama-SSB modulator afaneleka kakhulu kulezi zinhlelo ezintsha ngenxa yezimpawu zawo zesivinini esiphezulu kanye nokulahlekelwa okuphansi kokufakwa.
Emkhakheni wokuzwa kwe-optical fiber, izinhlelo ze-LFMCW LiDAR ezinama-SSB modulators zibonisa ukusebenza okuhle kakhulu ekuhlolweni okungenabungozi kanye nezinhlelo zokusebenza zokuzwa ezikude. Lolu hlobo lwesistimu lunokunemba okuphezulu kanye nesinqumo esiphezulu, lunganikeza ibanga elinembile kanye nokulinganisa isivinini, ngakho-ke lunezinhlelo zokusebenza eziningi ezindizayo, ezimotweni ezingenamuntu, ezinhlelweni zokuhamba ezihlakaniphile nakwezinye izinkambu.
Emkhakheni wocwaningo lwesayensi, ama-modulators e-SSB asetshenziswa kumaphrojekthi ahlukahlukene ocwaningo asezingeni eliphezulu, njenge-quantum computing, i-ultrafast optics, i-spectroscopy, njll. I-bandwidth yayo yokusebenza ephezulu kanye nesignali ye-optical ephumayo eqinile kunikeza indawo efanele yokuhlola yale misebenzi.
Emkhakheni wezokwelapha osafufusa, ama-modulators e-SSB nawo asetshenziswa ukuthuthukisa amasu amasha okuthwebula izithombe nokuthola ama-optical. Isibonelo, i-multi-photon microscopy esebenzisa ama-modulators e-SSB inganikeza izithombe zezicubu zebhayoloji ezinesinqumo esiphezulu nezincazelo ephezulu, okunemiphumela ebalulekile ekuxilongweni nasekwelashweni kwezokwelapha. Kulezi zindawo, njengoba ubuchwepheshe buqhubeka nokuthuthuka, kunengqondo ukukholelwa ukuthi kuzoba nokusungula izinto ezintsha kanye nempumelelo eyengeziwe esikhathini esizayo.
Iyunithi yokuguqulwa kwe-SSB yochungechunge olucindezelwe yenkampani ye-SSB iwumkhiqizo ohlanganiswe kakhulu onamalungelo obunikazi obuzimele be-Rofea Optoelectronics. Ihlanganisa i-modulator ye-electro-optic esebenza kahle kakhulu, i-microwave amplifier, i-adjustable phase shifter kanye nesekethe yokulawula i-bias ukuze kufezwe umphumela wokuguqulwa kwe-SSB optical. Ukusebenza kwayo kuthembekile, kulula ukuyisebenzisa, futhi inezinhlelo eziningi zokusebenza kuma-photonics e-microwave kanye nezinhlelo zokuzwa i-fiber optical.
Ngokwesakhiwo, i-SSB modulator isebenzisa i-Mach-Zehnder modulator, i-bias controller, i-RF driver, i-phase shifter nezinye izingxenye ezidingekayo ezihlanganiswe ndawonye. Lo mklamo wenza inqubo yokusebenzisa ibe lula kakhulu futhi wandisa ukuthembeka kohlelo. Izici zayo zokulahlekelwa okuphansi kokufakwa, i-bandwidth ephezulu yokusebenza kanye nesignali ye-optical ephumayo eqinile zenza ukuthi ibe nethuba elibanzi lokusebenzisa emkhakheni wocwaningo lwesayensi.
