Overview of Optical Communications Optical communications using LED’s and diode lasers are employed in many situations. Advantages Difficult to intercept optical systems by unauthorized agents Greater amount of information can be communicated that by traditional radio methods Disadvantages Difficult to align the transmitters and receivers Fog, rain and aerosols cause degradation of the signal
Optical Communications Between Satellites Advantages In low earth orbit (LEO) problems with aerosols, rain and fog are minimal Difficulties Aligning the beams between moving satellites
Varied Approaches Optical communication could be established using LEDs, diode lasers or other optical emitters Diode Lasers Produce more energy than LEDs but the beams are highly collimated and therefore difficult to be detected by the optical receivers Other Optical Emitters Other optical transmitters can be employed but generally require higher voltages and currents than LEDs and are still being considered LEDs Optical output is weaker than that of a diode laser, but they can be purchased to emit over a wider solid angle and are therefore easier to detect
