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. WebWe report direct measurements of the frequency dependence of the optical group delay for a number of optical components commonly used in femtosecond optics. We have investigated the group-delay errors that occur on reflection from metal and dielectric mirrors under various conditions and passage through devices that introduce angular dispersion. …
