Paper Abstract

Starting with a piece of PMMA (2 mm by 2 cm by 5 cm) a pattern for an integrated version of an optical gas sensor is recorded using computer controlled carbon dioxide laser beam etching. The sensor principle is the ATR-leaky mode spectroscopy using the shift of the plasmon resonance. Divergent light is created by optical fiber coupling. The resonance shift is observed with an array detector.
