I-Rof Bias Point Controller imodyuli yolawulo lwe-bias oluzenzekelayo lwe-lithium niobate MZ modulator
I-ROFImodyuli yokulawula i-bias ezenzekelayo yochungechunge lwe-ABC-MZ isetyenziselwa ulawulo lwe-bias oluzenzekelayo lwe-lithium niobate MZ modulator, enokwenza i-modulator isebenze ngokuzinzileyo kwinqanaba eliphantsi, kwinqanaba eliphezulu okanye kwinqanaba le-orthogonal (ummandla othe tye). Le modyuli ikwadityaniswe ne-1/99 coupler, enokulawula ukutshintshela kwendawo yokusebenza ngezibuko le-serial langaphandle, kwaye ixhasa imo yohlengahlengiso lwesandla, efanelekileyo kwiimodyuli ezahlukeneyo ze-wavelength kunye nezicelo, kwaye ifanelekile kakhulu kwiilabhoratri zaseyunivesithi ukwakha iimvavanyo zedesktop.

Umlawuli we-Bias we-Ultra Compact DP-IQ Modulator Umlawuli we-Bias oZenzekelayo
Isilawuli se-Rofea' modulator bias senzelwe ngokukodwa ii-modulators zeMach-Zehnder ukuqinisekisa imeko yokusebenza ezinzileyo kwiindawo ezahlukeneyo zokusebenza. Ngokusekelwe kwindlela yaso yokucubungula isignali edijithali ngokupheleleyo, isilawuli sinokubonelela ngokusebenza okuzinzileyo kakhulu.
Isilawuli sifaka isignali ye-dither enomsinga ophantsi, i-amplitude ephantsi kunye ne-bias voltage kwi-modulator. Ihlala ifunda isiphumo esivela kwi-modulator kwaye imisela imeko ye-bias voltage kunye nempazamo ehambelana nayo. I-bias voltage entsha iya kusetyenziswa emva kwamagama ngokwemilinganiselo yangaphambili. Ngale ndlela, i-modulator iqinisekiswa ukuba isebenza phantsi kwe-bias voltage efanelekileyo.
