Chii chinonzi Optical Modulator?
Optical Modulatorzvinowanzoshandiswa kunyengedza zvivakwa zvematehwe echiedza, senge laser matanda. Chishandiso chinogona kunyengera zvivakwa zvebanda, sesimba renzvimbo kana chikamu. Modulator zvinoenderana nechimiro chebhandi rakadururwa rinonziIntensity modulator, Phase Modulator, Polarization Modulator, Spatial Optical Modulator, etc. Yakasiyana mhando dzevamwari dzinogona kushandiswa mukushandiswa kwakasiyana, seruratidzira mhandara
Optical Modulator Type
Kune akati wandei akasiyana marudzi evanofamba-famba:
1. Acousto-Optic Modulator ndeye modulator yakavakirwa pane acousto-optic mhedzisiro. Izvo zvinoshandiswa kuchinja kana kuenderera mberi kugadzirisa iyo yekukwira kweiyo laser beam, shandura iyo freed frequency, kana shandura kutungamira kwenzvimbo.
2. TheElectro-Optic Modulatorinoshandisa electro-optic mhedzisiro muBubble Kerrs Bhokisi. Vanogona kunongedza iyo Polarization State, chikamu, kana bhegi simba, kana kuti ishandiswe pulse kubviswa sezvakataurwa muchikamu pane ultrashort pulse amplifiers.
3. Mirairo yemagetsi yekunyora ndeyekuti modulator modulator inoshandiswa pane imwe data transmitter mukukurukurirana.
.
5. Fiber optic modulators inogona kuve yakavakirwa pane dzakasiyana siyana. Inogona kuve yechokwadi fiber optic mudziyo, kana inogona kuve chikamu chemuviri chine fiber pigtails.
6 Ivo vanogona zvakare kushandiswa sevheti yemwenje mhirizhonga, zvichireva kuti kutapurirana kunosiyana nenzvimbo, iyo inogona kushandiswa mumidziyo yekuratidzira.
7. Iyo yekushandura dhisiki inogona kuchinja simba renzvimbo, iyo inoshandiswa mune zvimwe zviitiko zvakaringana (sekushandisa kukiya-muAmplifiers).
8. Microomekancal modulators (microomekantic system, mems) yakadai seSilicon-based malves uye maviri-emhando girazi arrays anonyanya kukosha mukuratidzira.
9 Fiber yakajairwa modulators, kazhinji wave waveguide modulators ine fiber pigtails, zviri nyore kubatanidza mune fiber optic system.
Kushandisa kweOptical Modulator
Optical modulators ine huwandu hwakawanda hwekushandisa muminda yakawanda. Iyi inotevera inzvimbo huru dzekushandisa dzevashandisi vepamhepo uye yavo chaiyo application:
1. Optical kutaurirana: mune Optical kutaurirana masisitimu, modipolitors inoshandiswa kunongedza iyo amplitude, frequency uye chikamu chechiratidzo chechiratidzo kuitira kuendesa ruzivo. Izvo zvinowanzoshandiswa mumatanho akakosha senge photoelectrical kushandurwa, kusarudzika chiratidzo chekushandura uye demodulation. Electro-Optic modulators inonyanya kukosha mune yakakwirira-yekumhanyisa masisitimu ekutaurirana Nekusimudzira kusimba kana chikamu chechiratidzo chechiratidzo, iyo mabasa ekuchinja kwechiedza, modulation rate control uye masaini modulation inogona kuzadzikiswa
2.. Semuenzaniso, nekumhanyisa chikamu kana amplitude yechiedza, fiber optic gyroscopes, fiber optic inomanikidza sensors, etc. inogona kuzadziswa
3. Kuchengetedza Optical uye kugadzirisa: Optical modulators inoshandiswa kune Optical yekuchengetedza uye yekugadzirisa mafomu ekugadzirisa. In Optical memory, yemanyorerwo modulators inogona kushandiswa kunyora uye kuverenga ruzivo mukati uye kunze kweyenzi yemidhiya. Mune yekugadzirisa nyaya, iyo moducatior yemufananidzo inogona kushandiswa kuumbwa, kusefa, modulation uye demodulation yeasikoptical masaini
4.. Semuenzaniso, mwanasikana wechiedza anogona kuita maviri-ezvimedu chikamu chekudaidzira kuti uchinje urefu hwekutarisa uye kutarisa kwakadzama kwengoro
5. Optical kuronga: Iyo Optical Modulator inogona kudzora kukura uye kuwanda kwechiedza, nekudaro kuderedza kana kudzikisira ruzha rwepfungwa mune system chaiyo. Inogona kushandiswa mune Optical amplifiers, lasers uye fiber optic transcation system yekuvandudza chiratidzo-kune-ruzha ratio uye kuita kweiyo system
6. Zvimwe zvekushandisa: Electro-Electro-Optical Modulators anoshandiswawo mukuongorora kwekuongorora, radar masisitimu, kurapwa uye zvimwe zvekurapa uye mamwe minda. MuSpectroscopy, electro-Optical Modulator inogona kushandiswa sechinhu cheSturity spectrum quantzer yekuongorora kwekutanga uye kuyerwa. MuRadar system, Electro-Optic Modulator inoshandiswa kune signal modulation uye demonline. Mukurapa kwekurapa, Electro-Optic modulators inoshandiswa mukufungidzira uye kurapa.
