Abstract
A method for fabricating a sensor is provided, with the sensor including a reflective element and an optical fiber positioned relative to the reflective element such that light emitted from the optical fiber is reflected by the reflective element and propagates in an optical cavity between the optical fiber and the reflective element. The method includes positioning an element within the optical cavity. The element has a coefficient of thermal expansion and a thickness that compensate a refractive index change with temperature of a medium within the optical cavity.
Claims10
A method of fabricating a sensor, the method comprising:
- providing a movable element;
- positioning an optical fiber relative to the movable element to form an optical cavity such that light propagates in the optical cavity between the optical fiber and the movable element and is reflected by the movable element, the optical cavity comprising a medium having a refractive index change with temperature;
- and
- positioning an element within the optical cavity, the element having a coefficient of thermal expansion and a thickness that compensate the refractive index change with temperature.
