I-Rof Bias Point Controller imoduli yokulawula i-bias ezenzakalelayo ye-lithium niobate MZ modulator
I-ROFI-module yokulawula i-bias ezenzakalelayo yochungechunge lwe-ABC-MZ isetshenziselwa ukulawula i-bias ezenzakalelayo ye-modulator ye-lithium niobate MZ, engenza i-modulator isebenze kahle endaweni ephansi kakhulu, endaweni ephezulu kakhulu noma endaweni eqondile (isifunda esiqondile). I-module iphinde ihlanganiswe ne-1/99 coupler, engalawula ukushintsha kwendawo yokusebenza nge-port yangaphandle ye-serial, futhi isekela imodi yokulungisa ngesandla, efanelekile kuma-modulator ahlukahlukene kanye nezinhlelo zokusebenza ze-wavelength, futhi ifanele kakhulu ama-laboratories aseyunivesithi ukwakha izivivinyo zedeskithophu.

Isilawuli se-Bias se-Ultra Compact DP-IQ Modulator Isilawuli se-Bias esizenzakalelayo
Isilawuli se-Rofea' modulator bias senzelwe ngokukhethekile ama-modulators e-Mach-Zehnder ukuqinisekisa isimo sokusebenza esizinzile ezindaweni ezahlukene zokusebenza. Ngokusekelwe endleleni yaso yokucubungula isignali egcwele idijithali, isilawuli singanikeza ukusebenza okuzinzile kakhulu.
Isilawuli sifaka isignali ye-dither ephansi, i-amplitude ephansi kanye ne-bias voltage ku-modulator. Siqhubeka sifunda umphumela ovela ku-modulator futhi sinquma isimo se-bias voltage kanye nephutha elihlobene. Kuzosetshenziswa i-bias voltage entsha ngemuva kwamagama ngokwesilinganiso sangaphambilini. Ngale ndlela, i-modulator iqinisekiswa ukuthi isebenza ngaphansi kwe-bias voltage efanele.
