Abstract
A package includes a cap with a solid-state light emitting device mounted within a recess in the cap. A plate is attached to the cap to define a hermetically sealed region in which the light emitting device is housed, and a base is attached to the plate. The plate and base are transparent to a wavelength of light emitted by the light emitting device. An optical wavelength selective element is disposed between the plate and the base to select the wavelength of light to exit the package through the base.
