Modulator ea electro-opticke sesebelisoa sa bohlokoa sa ho fetola lets'oao la laser le tsoelang pele ho sebelisoa data, maqhubu a seea-le-moea le matšoao a oache. Meaho e fapaneng ea modulator e na le mesebetsi e fapaneng. Ka modulator ea optical, matla a leqhubu la leseli a ka fetoloa eseng feela, empa hape le boemo ba mohato le polarization ba leqhubu la leseli bo ka fetoloa. Li-modulator tsa electro-optic tse sebelisoang haholo ke Mach-Zehnderli-modulator tsa matlaleli-modulator tsa mohato.
TheModulator ea matla a LiNbO3e sebelisoa haholo tsamaisong ea puisano ea optical e potlakileng haholo, ho lemoha ka laser le litsamaisong tsa ROF ka lebaka la ts'ebetso ea electro-optic hantle. Letoto la R-AM le thehiloeng sebopehong sa MZ push-pull le moralo oa X-cut, le na le litšobotsi tse tsitsitseng tsa 'mele le tsa lik'hemik'hale, tse ka sebelisoang litekong tsa laboratori le litsamaisong tsa indasteri.

1. Modulator ea sistimi e tlameha ho ba le karolelano e phahameng ea ho fela. Tšobotsi ea modulator ea sistimi e etsa qeto ea hore karolelano e phahameng ka ho fetisisa ea ho fela e ka finyelloa.
2. Ho lokela ho hlokomeloa hore polarization ea leseli le kenang la modulator e sebetsanoe le eona. Li-modulator li na le kutloelo-bohloko ho polarization. Polarization e nepahetseng e ka ntlafatsa karolelano ea ho fela ha khanya ho feta 10dB. Litekong tsa laboratori, hangata ho hlokahala molaoli oa polarization.
3. Balaoli ba leeme ba nepahetseng. Tekong ea rona ea karolelano ea ho fela ha DC, karolelano ea ho fela ha 50.4dB e fihletsoe. Leha leqephe la data la moetsi oa modulator le thathamisa 40dB feela. Lebaka la ntlafatso ena ke hore li-modulator tse ling li tsamaea ka potlako haholo. Balaoli ba leeme ba Rofea R-BC-ANY ba ntlafatsa motlakase oa leeme motsotsoana o mong le o mong ho netefatsa karabelo e potlakileng.
ROF e 'nile ea tsepamisa maikutlo ho lipotoloho tse kopantsoeng tsa electro-optic le likarolo ka lilemo tse leshome. Re etsa li-modulator tse kopantsoeng tsa optical tse sebetsang hantle haholo 'me re fana ka litharollo le lits'ebeletso tse ncha bakeng sa bafuputsi ba saense le baenjiniere ba indasteri. Li-modulator tsa Rofea tse nang le motlakase o tlase oa drive le tahlehelo e tlase ea ho kenya li ne li sebelisoa haholo-holo kabong ea linotlolo tsa quantum, litsamaisong tsa radio-over-fiber, litsamaisong tsa ho lemoha laser, le puisano ea optical ea moloko o latelang.
Hape re fana ka di-modulator tse ngata tse ikgethang bakeng sa ho iketsetsa, tse kang di-modulator tsa phase ya 1*4 array, Vpi e tlase haholo, le di-modulator tsa ultra-high extinction ratio, tse sebediswang haholo diyunivesithing le ditheong. Ho feta moo, re boetse re hlahisa RF amplifier (modulator driver) le taolo ya BIAS, photonics detector jj.
Nakong e tlang, re tla tswela pele ho ntlafatsa letoto la dihlahiswa tse seng di ntse di le teng, ho aha sehlopha sa botekgeniki sa profeshenale, ho tswela pele ho fa basebedisi dihlahiswa tsa boleng bo hodimo, tse tshepahalang, tse tswetseng pele le ditshebeletso tsa botekgeniki.
