5. The drift time is the time taken by carriers to drift through the whole width W of the space-charge region. 16) The linearly graded profile is a more realistic approximation for junctions formed by deep diffusions (NW or PW) into moderate or heavily doped substrates. 19) The drift time (td ) is determined by the drift velocity v and by the width of the drift zone W. The drift velocity v depends on μ and E. Furthermore, μ depends on the doping concentration and electric field. The doping concentration and the reverse bias voltage VR applied to the photodiode determine the electric field values.
This is a wanted effect since it improves the speed of the photodetector. In contrast, carrier diffusion occurs when no electric field is present and movement of the charge carriers is slow, which reduces the bandwidth of the whole detector. This means for a fast photodiode, most of the charge carriers must be photo-generated in a zone where a strong electric field exists. Electron-hole pairs generated in semiconductor with zero electrical field (region 1 and 2 in Fig. 3) move slowly due to diffusion effect.
The group velocity associated with the fundamental mode is frequency dependent because of chromatic dispersion. As a result, different spectral components of the pulse travel at slightly different group velocities, a phenomenon referred to as group-velocity dispersion (GVD), intramodal dispersion, or simply fiber dispersion [4]. 3) where D is called the dispersion parameter and is expressed in units of ps/(km·nm). 3 µm [D ≤ 1 ps/(km·nm)]. For a semiconductor laser, the spectral width Δλ is around 2–4 nm.
