Ukuhlaziywa kwesimiso semodyuli ye-photoelectricI-modulator ye-Mach Zehnder

Okokuqala, umqondo oyisisekelo we-modulator ye-Mach Zehnder

I-modulator ye-Mach-Zehnder iyi-modulator ye-optical esetshenziselwa ukuguqula izimpawu zikagesi zibe izimpawu zokukhanya. Isimiso sayo sokusebenza sisekelwe kumphumela we-electro-optical, ngokusebenzisa insimu kagesi ukulawula inkomba yokukhanya ekhanyayo endaweni ukuze kufezwe ukuguqulwa kokukhanya, ukuhlukanisa ukukhanya kokufaka kube izimpawu ezimbili ezilinganayo emagatsheni amabili okukhanya e-modulator.
Izinto ezisetshenziswa kula magatsha amabili e-optical ziyizinto ze-electro-optical, lapho inkomba yazo yokukhanya iyahlukahluka ngobukhulu besiginali kagesi esetshenziswa ngaphandle. Njengoba ushintsho lwenkomba yokukhanya kwegatsha le-optical luzobangela ushintsho lwesigaba sesiginali, lapho ukuphela kokuphuma kwe-modulator yesiginali yamagatsha amabili kuhlanganiswa futhi, isiginali ye-optical eyenziwe izoba isiginali yokuphazamiseka enoshintsho ekuqineni, okulingana nokuguqula ushintsho lwesiginali kagesi lube ushintsho lwesiginali ye-optical, kanye nokuqaphela ukuguqulwa kwamandla okukhanya. Ngamafuphi, i-modulator ingaqaphela ukuguqulwa kwamabhande aseceleni ahlukene ngokulawula i-voltage yayo ye-bias.

Okwesibili, indima kaI-modulator ye-Mach-Zehnder

I-modulator ye-Mach-Zehnder isetshenziswa kakhulu ku-ukuxhumana ngefayibha yokukhanyakanye neminye imikhakha. Ekuxhumaneni nge-fiber optic, amasignali edijithali adinga ukuguqulwa abe amasignali optical ukuze adluliselwe, kanti ama-modulators e-Machzender angaguqula amasignali kagesi abe amasignali optical. Indima yawo ukufeza ukudluliselwa kwesignali okusheshayo nokuseqophelweni eliphezulu ezinhlelweni zokuxhumana nge-fiber optical.

I-modulator ye-Mach Zehnder ingasetshenziswa futhi ocwaningweni lokuhlola emkhakheni we-i-optoelectronicsIsibonelo, ingasetshenziswa ukwenza imithombo yokukhanya ehambisanayo kanye nokusebenzisa imisebenzi ye-single-photon.

Okwesithathu, izici ze-modulator ye-Mach Zehnder

1. I-modulator ye-Mach Zehnder ingaguqula amasignali kagesi abe amasignali okukhanya ukuze ifinyelele ukudluliswa kwamasignali ngesivinini esiphezulu nekhwalithi ephezulu.

2. Uma i-modulator isebenza, idinga ukusetshenziswa namanye amadivayisi afana nemithombo yokukhanya, izitholi zokukhanya, njll., ukuze kwakhiwe uhlelo oluphelele lokuxhumana ngefayibha yokukhanya.

3. I-modulator ye-Mach Zehnder inezici zesivinini sokuphendula okusheshayo kanye nokusetshenziswa kwamandla okuphansi, okungahlangabezana nezidingo zokuxhumana okusheshayo.

【 Isiphetho】

I-modulator ye-Mach Zehnder iyi-modulatori-modulator yokukhanyaisetshenziselwa ukuguqula isignali kagesi ibe isignali yokukhanya. Indima yayo ukufeza ukudluliswa kwesignali ngesivinini esiphezulu, nekhwalithi ephezulu ezindaweni ezifana nokuxhumana ngefayibha yokukhanya. I-Mach zender modulator inezici zokuphendula okusheshayo kanye nokusetshenziswa kwamandla okuphansi, futhi ingenye yamadivayisi abalulekile ohlelweni lokuxhumana ngefayibha yokukhanya.
