Modulation efficiency of a LiNbO3 waveguide electro-optic intensity modulator operating at high microwave frequency.
نویسندگان
چکیده
The modulation efficiency, at high-frequency microwave modulation, of a LiNbO(3) waveguide electro-optic modulator is shown to be degraded severely, especially when it is used as a frequency translator in a Brillouin-distributed fiber-sensing system. We derive an analytical expression for this attenuation regarding the phase-velocity mismatch and the impedance mismatch during the modulation process. Theoretical results are confirmed by experimental results based on a 15 Gb/s LiNbO(3) optical intensity modulator.

Hybrid amorphous silicon (a-Si_H)–LiNbO3 electro-optic modulator
Here we report the demonstration of a GHz-speed Lithium Niobate (LiNbO3) modulator that uses an amorphous Silicon waveguide to strongly confine light. The compact (o1 mm) modulator is realized by low-temperature deposition of hydrogenated amorphous Silicon (a-Si:H) onto a x-cut LiNbO3 substrate. The a-Si:H provides tight waveguide mode confinement while allowing strong evanescent coupling to th...
