“…Conventionally, techniques using open waveguide, monopole, or dipole-type metal probes [1] [2] have been pursued for electromagnetic measurements, although the nonlinear-optical techniques of electro-optic (EO) [3] [4] and magnetooptic (MO) sampling and sensing [5] [6] have also been investigated. Features making these nonlinear-optical techniques promising are their broad bandwidth (for EO probing, typically into the THz regime for short-duration, timedomain transients) and a spatial resolution on the order of the size of the laser beam diameter or even less.…”

The concept and implementation of a near-field microwave measurement system that relies on the Pockels effect in fiber-coupled, semi-insulating GaAs probes to acquire polarization-sensitive maps of electric-field patterns in close proximity to antenna arrays, integrated circuits, and packaged components, is presented. The evolution of the electrooptic field-mapping technique, which has subsequently addressed magnetic-field characterization via magneto-optic sensing and temperature measurement through semiconductor band-gap modulation, will also be discussed. The use of emerging materials, such as diluted magnetic semiconductors, is also considered.

A novel approach to on-wafer measurement is proposed, which combines the drrcct elec*tro-optic probing technrque with a field theory based extraction technique for the modal voltages of all relevant modes at arbitrary internal ports of a (111-V) MMIC. The approach can be extended to obtain the complex modal amplitudes of forward and backward propagating waves on interconnecting transmission lines. This makes it a unique method for measurement of mode conversion in N-port components and t heir multimode s-parameter char,&erization.
