Patent abstract

Embodiments of the present invention provide a miniaturized spectroscopy system comprising a light source fabricated from porous silicon. Porous silicon light emitting devices can provide tunable, narrow, and directional luminescence. Advantageously, a porous silicon light source can be integrated into a silicon wafer based device thus simplifying the manufacture of a miniaturized spectros copy system and lab-on-a-chip type devices employing spectroscopic detection.
