Izinhlobo zama-electro-optic modulators zichazwe kafushane

I-modulator ye-electro-optical (I-EOM) ilawula amandla, isigaba kanye nokuhlukaniswa kwe-laser beam ngokulawula isignali nge-elekthronikhi.
Okulula kakhului-electro-optic modulatorkuyintoi-modulator yesigabaequkethe ibhokisi elilodwa lamaPockels kuphela, lapho insimu kagesi (esetshenziswa kukristalu yi-electrode) ishintsha ukubambezeleka kwesigaba somsebe we-laser ngemva kokungena kukristalu. Isimo sokwehlukanisa somsebe wesigameko ngokuvamile sidinga ukuhambisana nenye yezingqimba ezibonakalayo zekristalu ukuze isimo sokwehlukanisa somsebe singashintshi.

Kwezinye izimo kudingeka ukuguquguquka kwesigaba okuncane kakhulu (okuvamile noma okungajwayelekile). Isibonelo, i-EOM ivame ukusetshenziswa ukulawula nokuqinisa imvamisa ye-resonant yama-resonator e-optical. Ama-modulators e-Resonance avame ukusetshenziswa ezimweni lapho kudingeka ukuguquguquka kwesikhashana, futhi ukujula okukhulu kokuguquguquka kungatholakala nge-voltage yokushayela ephakathi nendawo kuphela. Ngezinye izikhathi ukujula kokuguquguquka kukhulu kakhulu, futhi ama-sidelobe amaningi (i-light comb generator, i-light comb) akhiqizwa ku-spectrum.

I-modulator ye-polarization
Kuye ngohlobo kanye nesiqondiso sekristalu engeyona i-linear, kanye nesiqondiso sensimu kagesi yangempela, ukubambezeleka kwesigaba nakho kuhlobene nesiqondiso se-polarization. Ngakho-ke, ibhokisi le-Pockels lingabona amapuleti wamagagasi alawulwa yi-multi-voltage, futhi lingasetshenziswa futhi ukulinganisa izimo ze-polarization. Ekukhanyeni kokufaka okune-linearly polarized (ngokuvamile ku-Angle engu-45° ukusuka ku-axis yekristalu), i-polarization yomsebe wokukhipha imvamisa i-elliptic, kunokuba imane ijikeleziswe yi-Angle kusuka ekukhanyeni kokuqala okune-linearly polarized.

I-modulator ye-Amplitude
Uma kuhlanganiswa nezinye izinto ezibonakalayo, ikakhulukazi ngama-polarizers, amabhokisi e-Pockels angasetshenziswa kwezinye izinhlobo zokuguquguquka. I-modulator ye-amplitude ku-Figure 2 isebenzisa ibhokisi le-Pockels ukushintsha isimo se-polarization, bese isebenzisa i-polarizer ukuguqula ushintsho esimweni se-polarization lube ushintsho ku-amplitude namandla okukhanya okudlulisiwe.
Ezinye izinhlelo zokusebenza ezijwayelekile zama-electro-optic modulator zifaka:
Ukushintsha amandla ogongolo lwe-laser, isibonelo, ekuphrinteni nge-laser, ukuqoshwa kwedatha yedijithali okusheshayo, noma ukuxhumana kwe-optical okusheshayo;
Kusetshenziswa ezindleleni zokuzinzisa imvamisa ye-laser, isibonelo, kusetshenziswa indlela ye-Pound-Drever-Hall;
Ukushintsha kwe-Q kuma-laser aqinile (lapho i-EOM isetshenziswa khona ukuvala i-resonator ye-laser ngaphambi kwemisebe evunguzayo);
Ukukhiya kwemodi okusebenzayo (ukulahleka kwesikhala sokuguquguquka kwe-EOM noma isigaba sokukhanya okuya nokubuya, njll.);
Ukushintsha ama-pulse kuma-pulse picker, ama-amplifiers empendulo enhle kanye nama-laser ajikayo.
