Ukwakhiwa kweizixhobo zonxibelelwano lwe-optical

Inkqubo yonxibelelwano ene-light wave njengomqondiso kunye ne-Optical fiber njengesixhobo sokudlulisa ibizwa ngokuba yi-Optical fiber communication system. Iingenelo zonxibelelwano lwe-optical fiber xa kuthelekiswa nonxibelelwano lwe-cable yendabuko kunye nonxibelelwano olungenazingcingo zezi: amandla amakhulu onxibelelwano, ilahleko ephantsi yokudlulisa, amandla okuphazamisana ne-electromagnetic, ubumfihlo obuqinileyo, kunye nezinto eziluhlaza ze-optical fiber transmission medium yi-silicon dioxide enendawo yokugcina eninzi. Ukongeza, i-optical fiber inezibonelelo zobukhulu obuncinci, ubunzima obulula kunye nexabiso eliphantsi xa kuthelekiswa ne-cable.
Lo mzobo ulandelayo ubonisa izinto zesekethe elula edibeneyo ye-photonic:ileza, ukusetyenziswa kwakhona kwe-optical kunye nesixhobo sokususa izinto ezininzi,isixhobo sokubona iifotokwayei-modulator.

Ulwakhiwo olusisiseko lwenkqubo yonxibelelwano lwe-optical fiber luquka: i-electrical transmitter, i-optical transmitter, i-transmission fiber, i-optical receiver kunye ne-electrical receiver.
Isignali yombane ekhawulezayo ifakwa kwikhowudi yitransmitter yombane ukuya kwitransmitter ye-optical, iguqulwe ibe yisignali ye-optical zizixhobo ze-electro-optical ezifana nesixhobo seLaser (LD), ize emva koko idityaniswe nefayibha yothumelo.
Emva kokudluliselwa komqondiso we-optical kumgama omde ngefayibha yemowudi enye, i-erbium-doped fiber amplifier ingasetyenziselwa ukukhulisa uphawu lwe-optical kunye nokuqhubeka nokudluliselwa. Emva kokuphela kokufumana i-optical, uphawu lwe-optical luguqulwa lube luphawu lombane yi-PD kunye nezinye izixhobo, kwaye uphawu lufunyanwa ngummkeli wombane ngokusebenzisa ukucubungula kombane okulandelayo. Inkqubo yokuthumela nokufumana imiqondiso kwicala elichaseneyo iyafana.
Ukuze kufezekiswe ukulungelelaniswa kwezixhobo kwikhonkco, i-optical transmitter kunye ne-optical receiver kwindawo enye zidityaniswa kancinci kancinci kwi-optical Transceiver.
Isantya esiphezuluImodyuli ye-transceiver ebonakalayoyenziwe yiReceiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) emelwe zizixhobo ezisebenzayo ze-optical, izixhobo ezingasebenziyo, iisekethe ezisebenzayo kunye nezixhobo ze-photoelectric interface zipakishiwe. I-ROSA kunye ne-TOSA zipakishwe nge-laser, ii-photodetectors, njl.njl. ngendlela yee-optical chips.

Ngenxa yeengxaki zobugcisa ezidibene nophuhliso lwetekhnoloji ye-microelectronics, abantu baqala ukusebenzisa ii-photon njengabathwali bolwazi ukuze bafumane i-bandwidth enkulu, isantya esiphezulu, ukusetyenziswa kwamandla okuphantsi, kunye ne-low delay photonic inteated circuit (PIC). Injongo ebalulekileyo ye-photonic integrated loop kukufezekisa ukuhlanganiswa kwemisebenzi yokuvelisa ukukhanya, ukudibana, ukuguqulwa, ukucoca, ukudlulisa, ukufumanisa njalo njalo. Amandla okuqala okuqhuba ii-photonic integrated circuits avela kunxibelelwano lwedatha, kwaye emva koko iphuhliswe kakhulu kwi-microwave photonics, ukucutshungulwa kolwazi lwe-quantum, i-nonlinear optics, ii-sensors, i-lidar kunye nezinye iindawo.
