Feedback Stabilized Fabry-Perot Interferometer
Applied Optics, 1973A method of stabilizing a Fabry-Perot interferometer with respect to a reference wavelength, while simultaneously stabilizing the parallelism of the flats, is described. The method consists of creating correcting signals proportional to the displacement of the fringe maxima of three auxiliary spectral sources with respect to a fixed reference point and

Das Laser-Funktionsprinzip basiert wesentlich auf der stimulierten Emission von Photonen. Diese stimulierte Emission ermoglicht die Realisierung von Sendedioden fur Weitverkehrssysteme mit entsprechend hoher Leistung und Bandbreite. Stimulierte Emission hangt eng zusammen mit stimulierter Absorption und spontaner Emission.

Optical fiber Fabry-Perot sensors
Applied Optics, 1988A new optical fiber Fabry-Perot (F.P.) temperature sensor is proposed and demonstrated. In particular, it can discern the temperature rise from the temperature drop. With this sensor, the temperature change and the direction of temperature change can be determined as a function of time. The basic concept has been verified experimentally. The results of

Intensity transmitted by a Fabry-Perot etalon with another internal Fabry-Perot interferometer
Applied Optics, 1981The intensity transmitted by a device made up of a F.P. etalon that contains another internal tunable F.P. has been studied. The theoretical predictions about the wavelengths of the intensity transmission maxima of the device are derived as functions of the optical path length of the internal F.P. An experimental check of the theoretical predictions is

A truly monopolar GaAs Fabry–Perot cavity Gunn laser is demonstrated. The device is grown by metalorganic chemical vapor deposition on a semi-insulating GaAs substrate and consists of an n=4.6×1017cm−3 doped GaAs active layer sandwiched between the AlxGa1−xAs(x=0.32) waveguiding layers.

Review of Scientific Instruments, 1964
A dilatometer based upon the principle of the Fabry-Perot interferometer is described. The device is capable of measuring displacements as small as 10−7 cm or less. The measurements are made directly in terms of the wavelength of a spectral line such as the green line of 198Hg.

Localization of partial discharge in transformer oil using Fabry-Pérot optical fiber sensor array
IEEE transactions on dielectrics and electrical insulation, 2018Partial discharge is the main reason for insulation deterioration and failure of high voltage electrical asset. Thus, the online detection and localization of partial discharge can provide the information on the equipment degradation characteristics, and
