IQ Modulator Series: Chii chinonzi Optical modulator?

Chii chinonzi Optical modulator?

Modulator yemazisoanowanzo shandiswa kugadzirisa hunhu hwemwenje, senge mwenje welaser. Mudziyo unogona kugadzirisa hunhu hwemwenje, senge simba re optical kana phase. Modulator zvichienderana nehunhu hwemwenje wakagadziriswa inonzimodulator yesimba, modulator yechikamu, polarization modulator, spatial Optical modulator, nezvimwewo. Mhando dzakasiyana dzema modulator dzinogona kushandiswa mumashandisirwo akasiyana, akadai se fiber optic communications, display devices, Q-switched kana mode-locked lasers, uye optical measurement.

Rudzi rwe modulator ye optical

Kune mhando dzakasiyana dzema modulator:

1. Acousto-optic modulator imodulator yakavakirwa pamhedzisiro yeacousto-optic. Inoshandiswa kuchinja kana kugadzirisa nguva dzose amplitude yemwaranzi yelaser, kuchinja frequency yechiedza, kana kushandura divi renzvimbo.

2. Iyomodulator yemagetsi-opticinoshandisa electro-optic effect mubhokisi rebubble Kerrs. Inogona kugadzirisa mamiriro epolarization, phase, kana beam power, kana kushandiswa pakubvisa pulse sezvataurwa muchikamu che ultrashort pulse amplifiers.

3. Modulator yemagetsi inonyudza imodulator yesimba inoshandiswa pakutumira data mukutaurirana kwe optical fiber.

(4) Mamodulators ekupindira, akadai seMach-Zehnder modulators, anowanzo shandiswa muma circuits akabatanidzwa e photonic ekutumira data re optical.

5. Mamodulator eFiber optic anogona kuvakirwa pamisimboti yakasiyana-siyana. Inogona kuva mudziyo wechokwadi wefiber optic, kana kuti inogona kuva chikamu chemuviri chine fiber pigtails.

6. Modulator yeLiquid crystal yakakodzera kushandiswa pamidziyo yekuratidza optical kana pulse shaper. Inogona zvakare kushandiswa se spatial light modulators, zvichireva kuti transmission inosiyana zvichienderana nenzvimbo, iyo inogona kushandiswa mumidziyo yekuratidza.

7. Dhisiki re modulation rinogona kuchinja simba remwenje nguva nenguva, iro rinoshandiswa mune zvimwe zviyero zve optical (sekushandisa ma lock-in amplifiers).

8. Ma micromechanical modulators (micromechanical systems, MEMS) akadai se silicon-based light valves uye two-dimensional mirror arrays anonyanya kukosha mu projection displays.

9. Ma "bulk optical modulators", akadai se "electro-optical modulators", anogona kushandisa nzvimbo yakakura ye "beam" uye anogonawo kushandiswa mumamiriro ezvinhu ane simba guru. Ma "fiber coupled modulators", anowanzova ma "waveguide modulators" ane "fiber pigtails", ari nyore kubatanidzwa muma "fiber optic systems".

Kushandiswa kweOptical modulator

MaOptical modulators ane mashandisirwo akasiyana-siyana muminda yakawanda. Aya ndiwo mashandisirwo makuru emaOptical modulators uye mashandisirwo awo chaiwo:

1. Kutaurirana kweOptical: Mumasystem ekutaurirana kweOptical, ma optical modulators anoshandiswa kugadzirisa amplitude, frequency uye phase ye optical signals kuitira kutumira ruzivo. Inowanzoshandiswa mumatanho akakosha akadai se photoelectrical conversion, optical signal modulation uye demodulation ‌. Ma electro-optic modulators akakosha zvakanyanya mumasystem ekukurukurirana kwe optical anomhanya zvakanyanya, anoshandiswa kushandura ma electronic signals kuita ma optical signals uye kuona data encoding uye transmission. Nekugadzirisa simba kana phase ye optical signal, mabasa e light switching, modulation rate control uye signal modulation anogona kuzadzikiswa ‌

2. Kunzwa kwemaziso: Muchina we optical modulator unogona kuona kuyerwa nekutarisa nharaunda nekuchinja hunhu hwechiratidzo che optical. Semuenzaniso, nekuchinja chikamu kana amplitude yechiedza, fiber optic gyroscopes, fiber optic pressure sensors, nezvimwewo zvinogona kuonekwa

3. Kuchengetedza nekugadzira Optical: MaOptical modulators anoshandiswa pakuchengetedza optical uye maapplication ekugadzirisa optical. Mu optical memory, ma optical modulators anogona kushandiswa kunyora nekuverenga ruzivo mukati nekunze kwe optical media. Mu optical processing, optical modulator inogona kushandiswa pakugadzira, kusefa, kugadzirisa uye kubvisa masaini e optical ‌

4. Kufungidzira kwemaziso: ma modulators emaziso anogona kushandiswa kugadzirisa chikamu uye amplitude yemwaranzi wechiedza, nokudaro achichinja hunhu hwemufananidzo mukufungidzira kwemaziso. Semuenzaniso, modulator yechiedza inogona kushandisa modulation yezvikamu zviviri kuti ichinje urefu hwefocal uye kudzika kwefocus yemwaranzi ‌

5. Kudzora ruzha rwemaziso: Modulator yemaziso inogona kudzora kusimba uye frequency yechiedza, nokudaro ichideredza kana kudzvinyirira ruzha rwemaziso musystem yemaziso. Inogona kushandiswa muma amplifiers emaziso, ma lasers uye masisitimu ekutumira fiber optic kuvandudza chiyero chesignal-to-noise uye mashandiro esystem ‌

6. Mamwe mashandisirwo: ma electro-optical modulators anoshandiswawo mukuongorora ma spectral, radar systems, medical diagnosis nedzimwe nzvimbo. Mu spectroscopy, electro-optical modulator inogona kushandiswa sechikamu che optical spectrum analyzer yekuongorora nekuyera ma spectral. Mu radar system, electro-optic modulator inoshandiswa mukuchinja ma signal modulation uye demodulation. Mukuongorora ma medical, electro-optic modulators inoshandiswa mu optical imaging and therapy ‌.
