Abstract :
The strict TM polarization dependence of intersubband absorption is relaxed in a nanopore lattice in which TE absorption is also allowed. By controlling the nanopore geometry, one can in principle achieve control over the polarization dependence of intersubband absorption. This has potential applications in various types of intersubband devices and in particular quantum well infrared photodetectors.
