Nanoscale quantum dot infrared sensors with photonic crystal cavity
12th Apr 2006, 19:05 GMT
K. T. Posani, V. Tripathi, S. Annamalai, N. R. Weisse-Bernstein, S. Krishna et al. We report high performance infrared sensors that are based on intersubband transitions in nanoscale self-assembled quantum dots combined with a microcavity resonator made with a high-index-contrast two-dimensional photonic crystal. The addition of the photonic crystal cavity increases the photocurre ... [Appl. Phys. Lett. 88, 151104 (2006)] published Wed Apr 12, 2006.
