Chii chinonzi Optical modulator?

Optical modulatoranowanzo shandiswa kushandura zvimiro zvemwenje wemwenje, senge laser matanda. Chigadzirwa chacho chinogona kushandura zvinhu zvedanda, zvakadai semagetsi emagetsi kana chikamu. Modulator zvinoenderana nehunhu hweiyo modulated danda inonziintensity modulator, phase modulator, polarization modulator, spatial Optical modulator, etc. Mhando dzakasiyana-siyana dzemodulator dzinogona kushandiswa mumashandisirwo akasiyana-siyana, akadai sefiber optic communications, zviratidzo zvekuratidzira, Q-switched kana mode-locked lasers, uye optical measurement.

Optical modulator mhando

Kune akati wandei akasiyana marudzi e modulator:

1. Acousto-optic modulator iri modulator inobva pane acousto-optic effect. Iwo anoshandiswa kushandura kana kuramba achigadzirisa amplitude ye laser beam, kushandura mwenje frequency, kana kushandura mafambiro enzvimbo.

2. Theelectro-optic modulatorinoshandisa iyo electro-optic mhedzisiro mububble Kerrs bhokisi. Ivo vanogona kuenzanisa iyo polarization mamiriro, chikamu, kana danda simba, kana kushandiswa kuburitsa pulse sezvakataurwa muchikamu che Ultrashort pulse amplifiers.

3. Magetsi absorption modulator is intensity modulator inoshandiswa pane data transmitter mu optical fiber communication.

(4) Kupindira modulators, senge Mach-Zehnder modulators, anowanzo shandiswa mumafotonic akabatanidzwa maseketi ekufambisa data.

5. Fiber optic modulators inogona kubva pane zvakasiyana-siyana zvemitemo. Inogona kunge iri yechokwadi fiber optic mudziyo, kana inogona kuve chikamu chemuviri chine fiber pigtails.

6. Liquid crystal modulator yakakodzera kushandiswa kune optical display equipment kana pulse shaper. Iwo anogona zvakare kushandiswa se spatial light modulators, zvichireva kuti kutapurirana kunosiyana nenzvimbo, iyo inogona kushandiswa mumidziyo yekuratidzira.

7. Iyo modulation disk inogona nguva nenguva kuchinja simba redanda, iro rinoshandiswa mune mamwe maitiro chaiwo optical (zvakadai sekushandisa lock-in amplifiers).

8. Micromechanical modulators (micromechanical systems, MEMS) yakadai se-silicon-based light valves uye maviri-dimensional mirror arrays inonyanya kukosha mukuratidza zviratidzo.

9. Bulk optical modulators, senge electro-optical modulators, inogona kushandisa nzvimbo yakakura yedanda uye inogona kushandiswa kune yakakwirira-simba mamiriro. Fiber yakasanganiswa modulators, kazhinji waveguide modulators ane fiber pigtails, ari nyore kubatanidza mune fiber optic masisitimu.

Kushandiswa kweOptical modulator

Optical modulators vane huwandu hwakasiyana hwekushandisa muminda yakawanda. Aya anotevera ndiwo makuru ekushandisa nzvimbo dzeOptical modulators uye mashandisirwo avo chaiwo:

1. Optical communication: Mune optical communication systems, optical modulators inoshandiswa kugadzirisa amplitude, frequency uye chikamu chezviratidzo zvemaziso kuitira kutumira ruzivo. Inowanzo shandiswa mumatanho akakosha senge photoelectrical shanduko, optical sign modulation uye demodulation. Electro-optic modulators inonyanya kukosha mumasisitimu ekukurumidzira ekutaurirana, ayo anoshandiswa kushandura masaini emagetsi kuita masaini ekuona uye kuona encoding uye kutapurirana data. Nekugadzirisa kusimba kana chikamu chechiratidzo chemaziso, mabasa ekuchinja kwechiedza, modulation rate control uye signal modulation inogona kuitika.

2. Optical sensing: Iyo optical modulator inogona kuona kuyerwa uye kutarisa kwezvakatipoteredza nekugadzirisa hunhu hwechiratidzo chechiratidzo. Semuenzaniso, nekugadzirisa chikamu kana amplitude yechiedza, fiber optic gyroscopes, fiber optic pressure sensors, nezvimwe zvinogona kuitika.

3. Optical kuchengetedza uye kugadzirisa: Optical modulators inoshandiswa kune optical storage uye optical processing applications. Mune yekuyeuka kwemaziso, optical modulators anogona kushandiswa kunyora uye kuverenga ruzivo mukati nekubuda muoptical media. Mukugadzira optical, iyo optical modulator inogona kushandiswa kugadzira, kusefa, modulation uye demodulation yemaziso masaini.

4. Optical imaging: optical modulators inogona kushandiswa kugadzirisa chikamu uye amplitude yechiedza chechiedza, nokudaro kuchinja maitiro echifananidzo mu optical imaging. Semuyenzaniso, light field modulator inogona kuita maviri-dimensional phase modulation kushandura yakatarisa kureba uye kutarisa kudzika kwedanda.

5. Optical noise control: Iyo optical modulator inogona kudzora kusimba uye kuwanda kwechiedza, nokudaro kuderedza kana kudzvinyirira optical ruzha mu optical system. Inogona kushandiswa mune optical amplifiers, lasers uye fiber optic transmission masisitimu kuvandudza chiratidzo-kune-ruzha chiyero uye kuita kwehurongwa.

6. Zvimwe zvinoshandiswa: electro-optical modulators inoshandiswawo mu spectral analysis, radar systems, chirwere chekurapa uye mamwe minda. Mune spectroscopy, electro-optical modulator inogona kushandiswa sechikamu che optical spectrum analyzer ye spectral kuongorora uye kuyerwa. Mune radar system, electro-optic modulator inoshandiswa kugadziridza chiratidzo uye demodulation. Mukuongororwa kwekurapa, electro-optic modulators inoshandiswa mukufungidzira kwemaziso uye kurapwa.
