Optical properties such as index of refraction and optical absorption of many chromophore-doped polymers are sensitive to the physical and chemical environment to which the polymers are exposed. Detection sensitivity is further enhanced by optical micro-resonator structures such as waveguide micro-ring resonator and fiber Bragg gratings. Chromophore-doped polymers also offer some desirable flexibility in device fabrication. Ultraviolet light and electron beam can reduce the index of refraction of the polymer. The photobleaching and electron beam bleaching methods form optical waveguides in a single fabrication step and do not involve solvents or wet chemicals, and can be applied to polymers that are not compatible with other waveguide fabrication techniques. This Paper provides an overview of the basic principles and designs of such sensors. A chemical sensor to detect trace explosives and a broadband fiber optic electric-field sensor are presented as practical examples.

“…Resonant sensors based on whispering gallery mode (WGM) microresonators [5][6][7][8][9][10] are among the most sensitive photonic E-field detectors. Initially WGM resonators were employed as radiofrequency (RF) receiver front-ends, functioning both as electronic mixers as well as filters, so that the entire receiver front end was simply comprised of the resonant electro-optic modulator (EOM) and a photodiode.…”

“…A polymer ring-based E-field sensor with minimal detectable field of 100 mV/m operating at 0.5 GHz speed was demonstrated experimentally. 7 Very recently a silicon-organic hybrid modulator driven by a bowtie antenna was used as a E-field sensor, and sensitivity at the level of 2.5 V/m was achieved for 8. 4 GHz signals.…”

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.

The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. We report the development of a broadband electric field sensor array technology to detect radio frequency (RF) electromagnetic energy. An approach based on planar electro-optical resonators is considered. We have developed sensors based on electro-optic polymers and sensors based on a hybrid material system consisting of silicon and lithium niobate. Test and measurement of fabricated sensors based on disperse red one electro-optic polymers yielded a sensitivity of 95 Volts per meter per root Hertz in a footprint of 170 micrometers by 270 micrometers.

Test and measurement of fabricated sensors based on disperse red one electro-optic polymers yielded a sensitivity of 95 Volts per meter per root Hertz in a footprint of 170 micrometers by 270 micrometers. The sensor based on hybrid silicon and lithium niobate was both more sensitive and more miniature. The demonstrated sensitivity was 4.5 Volts per meter per root Hertz and the footprint was 40 micrometers by 40 micrometers. We conclude that electro-optical resonators based on a hybrid material system of silicon and lithium niobate is a promising technology for broadband electric field sensor arrays.
