Optical group delay
WebThe measured group delay of a signal through an optical fiber exhibits a wavelength dependence due to the various dispersion mechanisms present in the fiber. It is often … WebOptical delay—usually phase—is particularly important in intrinsic sensors. The delays within an optical fiber can be modulated by physically changing its length (applying strain), by changing the isotropic pressure around the fiber, or by changing the temperature of the fiber.
