Electro-optic (EO) sensors, used for the nonperturbative detection of electric fields, are strongly influenced by inhomogeneities and deviations of birefringence within the nonlinear crystal. These effects can reduce optical phase coherence in the pr

Sr0.75Ba0.25NbO3 (SBN-75) has the tungsten-bronze structure with a tetragonal unit cell and exhibits electro-optic properties that are important for sensors. Due to its quaternary nature, its structural uniformity, integrity, and homogeneity become i

In bismuth-doped iron garnets, diamagnetic dilution of Fe with Ga is a well-known method to increase the Faraday rotation response under externally applied magnetic fields. It is found, however, that while this method improves responsivity at larger

In linear arrays of optically probed bismuth-doped iron garnet films, the Faraday rotation signal produced by an external magnetic field is a complex function of film shapes, stacking geometries, optical path length, and insertion losses. Studies of

Time domain terahertz spectroscopy is currently being widely used for various applications. A photoconductive antenna, which is also known as Auston-switch, is popular choice to produce a wideband terahertz beam for the time domain terahertz spectrom

We have developed and tested fiber optic electric and magnetic field sensors for ultra wideband (UWB) applications. The sensors are based on nonlinear effects in electro-optic (EO) and magneto-optic (MO) crystals. Unlike conventional antenna-based pr

An EO sensor measures an external electric field though a modulation of birefringence (detected optically) induced by the field on the nonlinear crystal. We have developed three different types of EO sensors: a free-field sensor to measure an electri

The sensitivity of an electro-optic (EO) field sensor depends inversely on the dielectric constant of the nonlinear crystal. In EO sensors based on lithium niobate the effective value of this dielectric constant is affected by dielectric relaxation e
