2. Guided transmissions
In the optical field, unlike the electrical field, there are several modes of propagation in the waveguide, depending on its dimensions (see Optical interconnections article). in this treatise):
when the cross-section of the guide is of the order of a few wavelengths, we speak of a single-mode guide;
when the cross-section is much larger, we speak of a multimode guide.
As we have already shown, single-mode optics offer the best performance in terms of bandwidth and linear attenuation, while multimode optics offer the best performance in terms of cost and ease of implementation.
The emergence of new optical sources combining high modulation speed and low power consumption, as well as ease of use, has enabled us to reduce production...
