Optical properties of anisotropic porous semiconductors

Semiconductors with parallel cylindrical pores possess positive birefringence for a single system of pores and negative one-for two mutually perpendicular systems of pores, in accordance with experiments. The matrix luminescence is polarized. For metal-filled pores, the system demonstrates a strong, frequency-dependent anisotropy of the optical properties and may exhibit plasmon amplification of luminescence.
