ABSTRACT:
The invention provides a light source for optical communication. The light source includes a spontaneous emission generator, an optical wavelength band narrower, an optical modulator, and an optical amplifier. The spontaneous emission generator generates non-coherent light which is band narrowed, modulated and amplified for a wireless optical communication in free space. The invention avoids a health hazard in respect of human eyes and remove a noise based on a spontaneous emission generated from an optical amplifier.
