6 Applications Optical communications Optical sensors Signal processing

7 Optical communications then... optical telegraph, 1792 bit rate : B<1bit/s... and now optical fibers

8 BL = přenosová rychlost × vzdálenost opakovačů Opticals fibers: - high speed

9 - low loss

14 Some types of IO waveguides How does light propagate in waveguide (or any other IO device)? Answer: Maxwell’s equations

15 Example: channel waveguide with thin metal layer
