摘要
A resonant-cavity enhanced detector operating in the mid-infrared at a wavelength around 3.6 mum is demonstrated. The device is based on a narrow-gap lead-salt heterostructure epitaxially grown on a BaF2(111) substrate. Below 140 K, the photovoltage clearly shows a single narrow cavity resonance, with a Deltalambda/lambda ratio of only 2% at 80 K.
