Abstract - Success in 94-GHz eletro-optic phase modulation using
the nonlinear organic MNA (2-methyl-4-nitroaniline) crystal is
reported. We believe this to be the highest electro-optic modulation
frequency ever achieved in a controlled manner. Dielectric constant,
loss tangent, and electro-optic constant of the MNA crystal were also
measured at 94-GHz, er'
=2.2, tan d
=0.09, and r11=30
10
pm/V.
