“…The advantages of optical fiber compared with copper wire are high voltage isolation, lightness, resistance against corrosion, and waterproofness. Therefore, these systems can power sensors in water, measurement equipment in severe electromagnetic noise environments, and medical equipment [3][4][5].…”

A 2-W supply optical powering system that maintains electrical isolation is described. The output power of this system is stable and higher than that of conventional systems, and is not affected by environmental stresses, such as bends in the optical fiber or increased PV cell temperature, owing to its feedback control function. The system mainly consists of laser diodes, optical fibers, photovoltaic (PV) cells, and a feedback control circuit, and can deliver 2 W of electrical power. In the feedback control circuit, the PV cell output current is compared to the target current, and the laser output is controlled to equalize them. The system also has a safety function that shuts down the laser if an optical fi ber is cut. The system was tested under a high-voltage condition, and the results indicate that it will be useful for driving sensors and measurement equipment used in high-voltage environments.

“…The material employed for the fabrication of these devices is typically InP and its compound alloys with Al and As. High efficiency and large bandwidth can be obtained when quantum confined stark effect (QCSE) is excited in the structure, achieving spectral operation in the range extended from 10 GHz to 6 GHz and a minimum detectable electric field intensity of 16 mV/m [113, 114]. …”

Nowadays, optical devices and circuits are becoming fundamental components in several application fields such as medicine, biotechnology, automotive, aerospace, food quality control, chemistry, to name a few. In this context, we propose a complete review on integrated photonic sensors, with specific attention to materials, technologies, architectures and optical sensing principles. To this aim, sensing principles commonly used in optical detection are presented, focusing on sensor performance features such as sensitivity, selectivity and rangeability. Since photonic sensors provide substantial benefits regarding compatibility with CMOS technology and integration on chips characterized by micrometric footprints, design and optimization strategies of photonic devices are widely discussed for sensing applications. In addition, several numerical methods employed in photonic circuits and devices, simulations and design are presented, focusing on their advantages and drawbacks. Finally, recent developments in the field of photonic sensing are reviewed, considering advanced photonic sensor architectures based on linear and non-linear optical effects and to be employed in chemical/biochemical sensing, angular velocity and electric field detection.

“…(b) EMC sensor: When the modulator at the end of a fibre is driven by an electrical input signal at the given position, the received optical signal can be used to measure the electrical signal quantitatively at the transmitter side and a field sensor results. Note that an electrical dc power required at the sensor side can be transmitted also optically employing a photovoltaic cell at the receiver side [12]. (c) Optoelectronic testing: A microminiaturized modulator chip working in reflection mode and coupled to the end of a fibre can be applied to measure electrical fields in free space with high spatial resolution.…”

Microwave photonics can be generally defined as the study of high-speed photonic devices operating at microwave or millimeterwave frequencies and their use in microwave or photonic systems. In this multidisciplinary field at the interface between microwave techniques, ultrafast electronics and photonic technologies, typical investigations include, for example, high-speed and microwave signal generation, processing and conversion as well as the distribution and transmission of microwave signals via broadband optical links. From pioneering experiments in the 70´s, this field of microwave photonics has paved the way for an enabling novel technology with a number of commercially important applications. This paper is intended to give an overview on this multidisciplinary field of microwave and millimeterwave photonics.
