Kodi Optical modulator ndi chiyani?

Optical moduleNthawi zambiri amagwiritsidwa ntchito kuwongolera mawonekedwe a nyali zowala, monga matabwa a laser. Chipangizocho chimatha kusintha mawonekedwe a mtengowo, monga mphamvu ya kuwala kapena gawo. Modulator molingana ndi momwe mtengo wosinthira umatchedwamphamvu modulator, gawo modulator, polarization modulator, spatial Optical modulator, etc. Mitundu yosiyanasiyana ya ma modulators ingagwiritsidwe ntchito pazinthu zosiyanasiyana, monga mauthenga a fiber optic, zipangizo zowonetsera, Q-switched kapena mode-locked lasers, ndi kuyeza kwa kuwala.

Mtundu wa Optical module

Pali mitundu ingapo ya ma modulators:

1. Acousto-optic modulator ndi modulator yochokera ku acousto-optic effect. Amagwiritsidwa ntchito kusinthira kapena kusinthira mosalekeza matalikidwe a mtengo wa laser, kusintha ma frequency a kuwala, kapena kusintha komwe akupita.

2. Theelectro-optic moduleamagwiritsa ntchito electro-optic effect mu bubble Kerrs bokosi. Atha kusinthira polarization state, gawo, kapena mphamvu yamtengo, kapena kugwiritsidwa ntchito pochotsa ma pulse monga tafotokozera mgawo la ultrashort pulse amplifiers.

3. Magetsi absorption modulator ndi intensity modulator yogwiritsidwa ntchito pa data transmitter mu optical fiber communication.

(4) Ma modulator osokoneza, monga ma modulators a Mach-Zehnder, nthawi zambiri amagwiritsidwa ntchito pamagawo ophatikizika a Photonic pakutumiza kwa data.

5. Fiber optic modulators akhoza kukhazikitsidwa pa mfundo zosiyanasiyana. Ikhoza kukhala chipangizo chowonadi cha fiber optic, kapena ikhoza kukhala gawo la thupi lomwe lili ndi ma pigtails.

6. Liquid crystal modulator ndi yoyenera kugwiritsa ntchito ku zida zowonetsera zowonetsera kapena pulse shaper. Atha kugwiritsidwanso ntchito ngati ma modulators owunikira, kutanthauza kuti kutumizira kumasiyanasiyana ndi malo, omwe angagwiritsidwe ntchito pazida zowonetsera.

7. Disiki yosinthira imatha kusintha nthawi ndi nthawi mphamvu ya mtengowo, yomwe imagwiritsidwa ntchito mumiyezo yodziwika bwino (monga kugwiritsa ntchito zolumikizira zotsekera).

8. Micromechanical modulators (micromechanical systems, MEMS) monga ma valve opangidwa ndi silicon-based light valves ndi magalasi awiri-dimensional arrays ndi ofunika kwambiri paziwonetsero zowonetsera.

9. Ma modulators ochuluka, monga ma electro-optical modulators, amatha kugwiritsa ntchito malo akuluakulu a mtengo ndipo angagwiritsidwenso ntchito kuzinthu zamphamvu kwambiri. Ma fiber ophatikizika ma modulators, omwe nthawi zambiri amakhala ma waveguide modulators okhala ndi fiber pigtails, ndiosavuta kuphatikiza mu fiber optic system.

Kugwiritsa ntchito Optical modulator

Optical modulators ali ndi ntchito zosiyanasiyana m'magawo ambiri. Zotsatirazi ndi madera akuluakulu ogwiritsira ntchito Optical modulators ndi ntchito zawo zenizeni:

1. Kuyankhulana kwa kuwala: M'machitidwe oyankhulana opangidwa ndi kuwala, optical modulators amagwiritsidwa ntchito kusinthira matalikidwe, mafupipafupi ndi gawo la zizindikiro za kuwala kuti athe kufalitsa zambiri. Amagwiritsidwa ntchito kwambiri pamasitepe ofunikira monga kutembenuka kwazithunzi, kusinthasintha kwa ma siginecha ndi kutsitsa. Ma electro-optic modulators ndi ofunikira kwambiri pamakina olumikizirana othamanga kwambiri, omwe amagwiritsidwa ntchito kutembenuza ma siginecha amagetsi kukhala ma siginecha owoneka bwino ndikuzindikira ma encoding ndi kutumiza. Mwa kusintha mphamvu kapena gawo la chizindikiro cha kuwala, ntchito za kusintha kwa kuwala, kuwongolera kusinthasintha komanso kusinthasintha kwa siginecha zitha kuzindikirika.

2. Optical sensing: Optical modulator imatha kuzindikira kuyeza ndi kuyang'anira chilengedwe posintha mawonekedwe a chizindikiro cha kuwala. Mwachitsanzo, posintha gawo kapena matalikidwe a kuwala, fiber optic gyroscopes, fiber optic pressure sensors, etc.

3. Kusungirako kwa kuwala ndi kukonza: Ma modulators a Optical amagwiritsidwa ntchito posungirako kuwala ndi ntchito zopangira kuwala. Pokumbukira kuwala, ma modulator owoneka amatha kugwiritsidwa ntchito kulemba ndi kuwerenga zambiri mkati ndi kunja kwa media media. Pokonza kuwala, makina opangira kuwala angagwiritsidwe ntchito popanga, kusefa, kusinthasintha ndi kutulutsa zizindikiro za kuwala.

4. Kujambula kwa kuwala: optical modulators angagwiritsidwe ntchito kusinthira gawo ndi matalikidwe a mtengo wa kuwala, potero kusintha maonekedwe a chithunzicho mu kujambula kwa kuwala. Mwachitsanzo, modulator yowala imatha kugwiritsa ntchito kusintha kwa magawo awiri kuti isinthe kutalika kwapakati komanso kuya kwa mtengo.

5. Kuwongolera phokoso la kuwala: The optical modulator imatha kulamulira mphamvu ndi mafupipafupi a kuwala, potero kuchepetsa kapena kupondereza phokoso la kuwala mu mawonekedwe a kuwala. Itha kugwiritsidwa ntchito mu amplifiers optical, lasers ndi ma fiber optic transmission systems kuti apititse patsogolo chiŵerengero cha phokoso ndi phokoso ndi machitidwe a dongosolo.

6. Ntchito zina: ma electro-optical modulators amagwiritsidwanso ntchito pofufuza zowonongeka, machitidwe a radar, matenda achipatala ndi zina. Mu spectroscopy, electro-optical modulator ingagwiritsidwe ntchito ngati chigawo cha optical spectrum analyzer pakuwunika ndi kuyeza. Mu radar system, electro-optic modulator imagwiritsidwa ntchito posintha ma siginecha ndikuwonetsa. Pozindikira zachipatala, ma electro-optic modulators amagwiritsidwa ntchito pojambula ndi kuchiritsa.
