“…49 It is worth noting that an all-dielectric lithium niobate (LiNbO 3 ) E-field sensor utilizing a Bragg-grating resonator mounted on an optical fiber tip has been realized and sensitivity of 0.5 V/m was achieved with the device. 50 The operation principle of that sensor is different from ours and the sensitivity is not as good as the sensitivity we predict and demonstrate.…”

We report on both theoretical and experimental studies of a photonic implementation of the electric (E-) field sensor using a probe made with all-dielectric RF-transparent elements. The geometrical dimensions of the electric field probe can be smaller than the wavelength of the measured electromagnetic field in the material. Our theoretical calculations show that the sensor allows detecting electric fields in a broad frequency range (100 Hz-20 GHz) with sensitivity better than 1 μV/[Hz1/2 m]. We demonstrate the sensor operating at X-band and validate the theoretical predictions.

“…Hole and/or trench depth and conicity also have very significant effect on light propagation through 1D PC structures. One simple 1D PC design is a Bragg grating, which has been used in various applications such as optical filters and more recently in electric field sensing [16]. Here, the numerical analysis results of the conicity and depth effects on a Bragg grating structure using Finite Element Method (FEM) are presented.…”

“…Perfectly matched layers (PMLs) were used as the structure boundaries. One simple 1D PC design is a Bragg grating which have been used in various applications such as optical filters and more recently in electric field sensing [16]. In order to satisfy the Bragg condition the period Λ must satisfy:…”

We report on novel focused ion beam fabrication techniques that can greatly improve the optical performance of photonic crystal structures. The finite depth and conicity effects of holes and trenches in Lithium Niobate (LN) photonic crystals have been theoretically analyzed, showing that the conicity causes refraction into the bulk sample, resulting in high transmission loss and no useful spectral features. The techniques for reducing the conicity angle from 25° to 5° were explained for the focused ion beam (FIB) milled structures.

“…Most recent results concerns the realization of photorefractive optical waveguides in Fe:LN by ion implantation [14]. Using these configurations, the first demonstrators of optical interconnections integrated optical circuits and sensors with a holographic stage have been already reported [15][16][17][18][19][20]. The main limitation of these optical processing schemes is that their full potential is nowadays difficult to miniaturize and integrate in a http://dx.doi.org/10.1016/j.optmat.2014.05.020 0925-3467/Ó 2014 Elsevier B.V.
