How to calculate group velocity of fiber
WebThe group delay is a convenient measure of the linearity of the phase with respect to frequency in a modulation system. Basic modulation system. A device's group delay can be exactly calculated from the device's phase response, but not the other way around.. The simplest use case for group delay is illustrated in Figure 1 which shows a conceptual … Webradius at which the fiber V parameter is 10. Use Fig. 9.2‐3 to estimate the propagation constants of all the guided modes with l=0. If the core radius is now changed so that …

WebWrong answer: 300,000,000 meters/second. Correct answer: it depends on the medium! Note to Microwaves101 readers: most textbooks use the term "phase velocity" denoted by vp interchangeably to also mean "velocity of light in a medium". This gets confusing, so we will avoid doing it and denote "velocity of light in a medium" by vlight. WebFor light propagating in a waveguide such as an optical fiber, the group velocity can be calculated by replacing the wavenumber k with β (the imaginary part of the …
