Wave polarization contains valuable information for electromagnetic signal processing; hence, the ability to manipulate it can be extremely useful in photonic devices. In this work, we propose designs solely comprised of one of the emerging and interesting two-dimensional media; Black Phosphorus. Due to substantial in-plane anisotropy, the simplest possible structure: a single slab of Black Phosphorus, can be very efficient and for manipulating the polarization state of electromagnetic waves. We propose Black Phosphorus films that filter the fields along one direction, or achieve large magnetic-free Faraday rotation, or convert linear polarization to circular; these slabs can be employed as  components in numerous mid-IR integrated devices.
