A review of Light Emitting Diodes (LEDs) and Injection Lasers (ILs), which are suited as signal sources in Fiber Optic Communication Systems is presented. LED and IL structures and their important operational characteristics, such as efficiency, power out, radiance,spectral emission, and lifetime are discussed.
