WebThe spectral width is often specified as a FWHM. It can be defined in terms of optical frequency (measured in Hz), angular optical frequency (in rad/s), or wavelength (in nm). … WebMay 12, 2014 · Optical −3 dB bandwidth is set to 20 GHz. Figure 5 b shows the “ through ” port transfer function and its group delay. It is evident that for the latter the dispersion is negligible as the group delay is constant and all the frequency components near to the resonant frequency roughly experience the same “pass-through” time.

WebThe sample file EDFA Basic Concepts.osd shows the basic characterization of the Erbium Doped Fiber Amplifier (EDFA). There are three design layouts: Gain Spectrum, Gain Saturation, and Amplifier Noise. They enable the characterization of the gain, noise figure, and output power under unsaturated and saturated signal input regime. Webwhere Δ ν is the (full width at half-maximum) linewidth (optical bandwidth).This coherence length is the propagation length after which the magnitude of the coherence function has dropped to the value of 1 / e..
