We report on the successful application of recently developed 2.3 μ m InP -based vertical-cavity surface-emitting lasers with a buried tunnel junction in a wavelength modulation spectroscopy measurement for carbon monoxide ( CO ) detection. The electrically pumped devices operate at room temperature under cw operation with stable single-mode emission and should allow for parts in 10 6 (ppm) level resolution measurement of CO with a standard optical setup.
