Abstract :
The potential for harnessing resonant-cavity (RC) effects in photonically structured mid-IR opto-electronic devices is explored experimentally and theoretically. Numerical modelling suggests that the effects of angular and spectral narrowing, combined with enhancements in external coupling efficiency, can lead to overall effective improvements in detectors and LEDs aimed at CH/sub 3/ and CO/sub 2/ gas sensing applications of up to *22. Experimental progress towards realising these figures is presented.
