EO Modulators

Preliminary specifications for thin film lithium niobate ultrawide band optical modulators

  • Thin film lithium niobate modulators allow perfect phase matching between RF signal and optical signal.
  • Ultra-wide band optical signal modulation is possible with thin film lithium niobate modulators.
  • The modulators use grating couplers for input and output coupling.
  • The modulator is provided with FC/PC connectors and polarization maintaining fibers.
