Abstract

We report on a new electro-optic field mapping system in which the electro-optic probe is integrated with an optical fiber. Due to the flexibility and the small size of the fiber, this new EO system has superior measurement versatility compared with other near-field measurement methods. Specially, it allows the insertion of a field probe directly within the interior of a microwave package to extract otherwise inaccessible amplitude and phase profiles. By utilizing gallium arsenide (GaAs) probe tips of two different crystal orientations, three complete electric field components are measured
