Abstract
An optical light source device includes a source member providing the emission of electromagnetic radiation wavelengths in the optical region of the spectrum, and at least one cavity waveguide member coupled with the electromagnetic radiation source member having a predetermined lateral dimension. The cavity waveguide member and predetermined dimension restrict the emission of electromagnetic radiation in the long wavelength non-visible infra-red range. In a preferred embodiment, the optical light source is formed with an array of optical light source members and associated cavity waveguide members.
