Abstract: In certain embodiments, a two-dimensional antenna block has (at least) two different types of dual-band, dual-polarization patch antennas that support (at least) two different frequency bands in the same polarization direction, where each feed line in the antenna block supports only one frequency band. Quad-band antenna blocks, having three different types of patch antennas supporting three different frequency bands in a first polarization direction and a common frequency band in a second polarization direction, can be tiled to form larger, quad-band antenna arrays. A particular (4×4) antenna block has, in the first polarization direction, eight antennas supporting a first frequency band, four antennas supporting a second frequency band, and four antennas supporting a third frequency band, where all sixteen antennas support the common frequency band. In a PCB implementation, three IC chips are mounted onto the bottom of the PCB to support antenna block communication and/or imaging operations.

Abstract: An optical receiver, e.g., for an Optical Supervisory Channel (OSC), whose optical front end comprises a polarization-diversity coherent optical receiver configured to receive a conventional intensity-modulated (e.g., OSC) signal. Four quadrature components of the received OSC signal detected by the polarization-diversity coherent optical receiver are sampled at a relatively high sampling rate and are used to calculate the Stokes parameters of the OSC signal. As a result, the Stokes parameters can be updated at the high sampling rate, which can be suitably selected to enable polarization tracking with a relatively high time resolution and/or at relatively high SOP-rotation speeds. The four detected quadrature components are appropriately combined in the receiver DSP to determine the intensity of the received OSC signal, which is then used in a conventional manner to recover the OSC data encoded therein.
