Abstract
The present invention relates generally to wavelength conversion devices and laser projection systems incorporating the same. According to one embodiment of the present invention, wavelength conversion devices are provided without limitation of their field of use to laser projection systems. For example, the wavelength conversion device may comprise a waveguide region comprising a relatively linear waveguide portion and a pair of lateral planar waveguide portions. The output face of the wavelength conversion device comprises a multi-component output face comprising a core portion and a pair of lateral portions. The lateral portions of the output face are configured to be relatively non-transmissive and the waveguide region is structured such that an optical signal propagating along the waveguide region will define relatively low intensity laterally distributed parasitic light in substantial alignment with the lateral planar waveguide portions along the lateral, non-transmissive portions of the output face. Additional embodiments are disclosed and claimed.
