Abstract:
1. An illuminator configured to emit light into an optical fiber, comprising: a baseplate; a first mount coupled to the baseplate and configured to support at least one pump light source configured to emit short-wavelength light; a second mount coupled to the baseplate and comprising a substrate having a layer of white phosphor disposed to receive the short-wavelength light and to emit white light in response; and a light collector disposed between the first mount and the second mount configured to collect the short-wavelength light at the white phosphor such that a brightness of the white light is greater than a brightness of the short wavelength light, wherein the at least one pump light source comprises a plurality of pump light sources arranged to illuminate the white phosphor from a plurality of respective directions; and the light collector comprises a plurality of collecting lenses, each collecting lens connected to a respective one of the pump light sources.
