Abstract:
An optical system for generating light comprising:a superluminescent diode that generates light having a predetermined wavelength; a doped optical fiber, having a first facet and a second facet, the doped fiber coupled to the superluminescent diode, for providing an optical path and for converting energy of light having the predetermined wavelength to light having first and second other wavelengths, each of the other wavelengths being less than the predetermined wavelength; first and second reflectors, positioned proximate to the first facet of the doped optical fiber, for selectively reflecting light having said first and second other wavelengths, respectively; and third and fourth reflectors, positioned proximate to the second facet of the doped optical fiber, for selectively reflecting light having said first and second other wavelengths, respectively.
