Abstract:
1. A light sources apparatus, comprising: a first light emitting diode for emitting light having a first wavelength, the first light emitting diode comprising angled facets to reflect incident light in a direction toward a top end of the first light emitting diode; a second light emitting diode for emitting light having a second wavelength, the second light emitting diode being disposed above the top end of the first light emitting diode, and the second light emitting diode comprising angled facets to reflect incident light in a direction toward a top end of the second light emitting diode; and a first distributed Bragg reflector disposed between the top end of the first light emitting diode and a bottom end of the second light emitting diode to allow light from the first light emitting diode to pass through and to reflect light from the second light emitting diode.
