Electro-Optical modulator (Eom) inodzora simba, chikamu uye polarization ye laser danda nemagetsi kudzora chiratidzo.
Zviri nyoreElectro-Optic ModulatoraPhase ModulatorInosanganisira chete one bhokisi re peckels, uko munda wemagetsi (unoshandiswa kune iyo crystal ne electrode) inoshandura kunonoka kwechikamu che laer Iyo polarization mamiriro enzvimbo inowanzoitika inowanzoenderana neimwe yeiyo yedenga rekristaro kuitira kuti iyo mamiriro ebhenji haachinje.
Mune zvimwe zviitiko chete zvidiki zvidiki chikamu chekujairana (nguva nenguva kana aPeriodic) inodiwa. Semuenzaniso, eom inowanzo shandiswa kudzora uye kusimbisa iyo yekukwira yekufambisa yeye Optical resonators. Misangano yemasononce inowanzo shandiswa mumamiriro ezvinhu apo nguva yekunyorwa inodiwa, uye kudzika kukuru kwekunyorwa kunogona kuwanikwa pamwe chete neyakajaira kutyaira voltage. Dzimwe nguva kudzika kwekunyorwa kwakakura kwazvo, uye akawanda mativi (maruva marara jenareta, chiedza chechiedza) anogadzirwa mune spectrum.
Polarization Modulator
Zvichienderana nerudzi uye nhungamiro yeiyo Notlinear Crystal, pamwe nekutungamira kwemunda chaiwo emagetsi, kunonoka kwechikamu kwakabatana zvakare neyekupuruzana. Naizvozvo, bhokisi rePOCKEL rinogona kuona akawanda-voltage inodzorerwa wave mahwendefa, uye inogona zvakare kushandiswa kunongedza polarization nyika. Zvemwenje yeLeently Polazed Chiedza (kazhinji pane angle ye45 ° kubva kuCrystal Axis inowanzoitika, pane kungotenderera nekona kubva kune yekutanga mutsara pachiedza.
Amplitude modulator
Paunenge wakasanganiswa nezvimwe zvinhu zvekushandisa, kunyanya nemapakeri, mabhokisi emabhokisi anogona kushandiswa mamwe marudzi ekujairwa. Iyo amplitude modulator muhuwandu 2 inoshandisa bhokisi rePockels kuti uchinje mamiriro ekunze, uye wobva washandisa polarizer
Zvimwe zvinowanzoitika zvekushandisa zveElectro-Optic modulator zvinosanganisira:
Ichimanikidza simba reiyo laser danda, semuenzaniso, nekuti Laser kudhinda, yakakwira-yakakwira dijitral data kurekodha, kana yakakwirira-yekumhanyisa kutaurirana.
Inoshandiswa muLaser frequency stablization scabisisms, semuenzaniso, uchishandisa iyo pound-drever-horo nzira;
Q Switches muSolid-State Lasers (uko EOM inoshandiswa kuvhara resonator resonator usati wadonha radiation);
Active Mode-Locking (eom modulation cavity kurasikirwa kana chikamu che-kutenderera-rwendo rwechiedza, nezvimwewo);
Switching pulses muPulse vateveri, yakanaka mhinduro amplififiers uye tilting lasers.
