ABSTRACT:
A dual wavelength optical source includes a monolithic integrated pair of series-opposition connected diodes, each fabricated for emitting light having a different wavelength than the other. Polarity of a common bias current conducted through the diodes is reversed for activating alternatively light emission from the diodes. Active emission regions of the diodes are stacked upon one another for efficiently coupling the resulting beams of the different wavelengths of emitted light through a surface into the core of a single mode optical fiber.
