This invention is a novel intrinsic fiber optic Fabry-Perot (FP) structure with a micrometric diameter tip. Theoretically it can be further minimized into a Nanometric taper. With such a tiny protrusion, the sensor can be inserted into most cells for intracellular measurements. The possibility of monitoring in-vivo biological processes within single living cells could greatly improve our understanding of cellular functions. With the FP cavity inside the fiber, the change of optical path difference (OPD) caused by the environment can be demodulated. This label-free detection method is very useful in biological areas, such as DNA hybridization detection. Compared with the current available techniques that usually consist of fluorescent dyes, our method greatly reduces the cost and increases the reliability. It provides a valuable tool for intracellular studies that have applications ranging from medicine to national security to energy production. In addition, the fabrication is simple including only cleaving, splicing, and etching. The signal is stable with high visibility. Last but not least, the structure shoes great promise for nanometric protrusion. Once this goal is achieved, the sensor can be inserted in to most cells with minimal invasiveness. This sensor can also be used in chemical applications.

This invention is a novel fiber optic Fabry-Perot (FP) structure with a micrometric diameter tip. The fabrication of micro scale probes has become essential in intracellular surgery, in cell sensing, manipulation, and injection. It is of great importance in many fields, such as genetics, pathology, criminology, pharmacogenetics, and food safety. With such a tiny protrusion, the sensor can be inserted into micron size cells, say, for DNA analysis. With the FP cavity inside the fiber, the change of optical path distance (OPD) caused by the environment can be demodulated. In addition, the structure is intrinsically capable of temperature compensation. What's more, it is simple, cost-efficient, and compact. Last but not least, the structure shows promise for nanometric protrusion. Once this goal is achieved, the sensor can be inserted into most cells. The sensor could pave the way for faster, more accurate medical diagnostic tests for countless conditions and may ultimately save lives by allowing earlier disease detection and intervention.

  • X. Wang, J. Xu and A. Wang, Novel Open Miniature Fabry-Perot Structures. Virginia Tech Intellectual Properties (VTIP:05.010), disclosure.

This invention is a novel fiber Fabry-Perot structure with only 125um in diameter. Its open structure breaks a new path to many applications in such area as industry, medicine, biology, chemistry and environment engineering. For example, in dynamic pressure measuring it can significantly reduce the effect of working point drifting due to the background pressure and fluctuations. Also, the open structure eliminates the effect of the trapped air expansion induced pressure, which is a common problem in the current hermetic pressure sensors. Another good example is chemical gas, such as hydrogen, detection and measurement. Furthermore, the sensors can be multiplexed and make distributed sensing and multi-parameter sensing possible. Other advantages include high temperature capability (600°C), biological compatibility, high signal strength, electromagnetic interference immunity, simple fabrication and low cost.

  • J. Xu, X. Wang and A. Wang, A Novel Miniature High Sensitive Fiber Optic Pressure Sensor. Virginia Tech Intellectual Properties (VTIP:04.093),disclosure. http://www.vtip.org/availableTech/technology.php?id=69081

This invention presents a novel miniature diaphragm based Fabry-Perot fiber optic sensor for measuring pressure or acoustic waves. The sensor is very small (<0.35mm) and can work at temperatures above 600°C with high sensitivity. By choosing different diaphragm thicknesses, pressure measurement range from 5psi to 15,000psi and frequency response from DC to 1MHz can be obtained. With very thin diaphragm, the sensor can detect acoustic wave as small as 0.01psi. Since the F-P cavity can be set from microns to millimeters in 5nm precision, this sensor can be used as an intensity or interferometric based sensor. And the epoxy-free design makes the sensor very reliable, durable and biocompatible, which is suitable for medical applications. In addition, the sensor is extremely low sensitive to temperature variations. In one word, this novel fiber optic pressure sensor possesses many advantages, such as small size, high sensitivity, high bandwidth, intrinsic immunity to electromagnetic interference (EMI), simplicity and low cost.
