WebA diaphragm-free fiber gas pressure sensor based on the extrinsic Fabry-Perot interferometer (EFPI) is proposed and experimentally demonstrated. The sensor is fabricated by fusion splicing a sandwich structure of a single mode fiber, a hollow core fiber (HCF), and a coreless fiber. A femtosecond (fs) laser is employed to drill a micro-channel ... WebNormally, Fabry–Pérot interferometers are devices with free-space light propagation between the mirrors. However, the term is sometimes also used for devices containing in a waveguide . For example, Fabry–Pérot lasers …

The varying transmission function of an etalon is caused by interference between the multiple reflections of light …
WebThe Fabry– Perot etalon is the most common interferometer structure used as a fiber optic sensor, since only one fiber is required to connect the sensor to the detector section. A classic Fabry–Perot interferometer is formed by two closely spaced, partially reflecting mirrors which form a resonant optical cavity with maximum optical transmission at …
In optics, a Fabry–Pérot interferometer (FPI) or etalon is an optical cavity made from two parallel reflecting surfaces (i.e.: thin mirrors). Optical waves can pass through the optical cavity only when they are in resonance with it.
