Properties of waveguide
WebEssentially all laser diodes are waveguide lasers, with optical guidance at least in one direction. Some low-power laser diodes even use single-mode guidance; the larger ones (e.g. broad area laser diodes and diode bars) exhibit multimode behavior at least in one direction. Waveguide structures are also used in some CO2 lasers . A waveguide is a structure that guides waves, such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction. Without the physical constraint of a waveguide, wave intensities decrease according to the inverse square law as they expand into three … See more The uses of waveguides for transmitting signals were known even before the term was coined.
