Optimal electro-optic sensor configuration for phase noise limited, remote field sensing applications

Abstract: Electro-optic (EO) sensors, used for the nonperturbative detection of electric fields, are typically configured to modulate an optical probe beam along a crystal direction in which the EO tensor coefficient is largest. However in fiber optic EO sensors, such configurations can be strongly limited by phase noise and cumbersome compensation optics. Our results demonstrate that a greater signal to noise ratio can be achieved by modulating along a crystal direction of low static birefringence, even when the active… Show more

“…In our TEM cell, the max field is 652 V/m at + 40 dBm input power, while the damage level of the all-dielectric EO sensor is known to be on the order of 1 MV/m [40]. We expect these types of probes to have an extremely wide, nearly 120 dB (V/m-MV/m) dynamic range.…”

“…Although the small sensor size is advantageous for many applications, its small sensing region reduces its sensitivity [4] in comparison with other electricfield sensing techniques [8]. There is a need to increase the sensitivity without a significant change in its sensing area.…”

“…To solve this problem, an optimal sensing scheme has been proposed to minimize the influence of quarter-wave plate on sensing signal [7]. The quarter wave plate can be removed if the π/2 optical bias is obtained from the total inner reflection-induced phase retardation in prism [8] or from the natural birefringence in uniaxial electrooptic crystal [9][10][11].…”
