Abstract

Aspects of the subject disclosure may include, a system that facilitates receiving electromagnetic waves having polarized modes propagating along a transmission medium, detecting according to an analysis of the electromagnetic waves that the transmission medium is birefringent thereby causing a differential delay between the polarized modes, and adjusting a configuration of a receiver receiving the electromagnetic waves to mitigate the differential delay between the polarized modes. Other embodiments are disclosed.

First claim

What is claimed is:

1. A device, comprising:
a receiver;
a processing system including a processor, the processing system being coupled to the receiver; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
receiving electromagnetic waves having polarized modes propagating along a transmission medium;
detecting according to an analysis of the electromagnetic waves that the transmission medium is birefringent thereby causing a differential delay between the polarized modes; and
adjusting the receiver to mitigate the differential delay between the polarized modes, the adjusting of the receiver comprising adjusting a rotation of the receiver about an outer surface of the transmission medium.

2. The device of claim 1 , wherein the adjusting of the receiver results in a phase adjustment of the electromagnetic waves being received.

3. The device of claim 1 , wherein the adjusting of the rotation of the receiver about the outer surface of the transmission medium comprises adjusting an azimuthal rotation of the receiver about the outer surface of the transmission medium.

4. The device of claim 3 , wherein an electromechanical motor performs the adjusting of the azimuthal rotation of the receiver.

5. The device of claim 1 , wherein the adjusting of the receiver results in adjusting one or more phases of one or more corresponding components of the electromagnetic waves.

6. The device of claim 1 , wherein a dispersion is caused by a first electromagnetic wave of the electromagnetic waves being misaligned with a first principal axis.

7. The device of claim 6 , wherein the dispersion is caused by a second electromagnetic wave of the electromagnetic waves being misaligned with a second principal axis.

8. The device of claim 7 , wherein the first electromagnetic wave is horizontally polarized and wherein the second electromagnetic wave is vertically polarized.

9. The device of claim 1 , wherein the receiver comprises a cross planar coupler.

10. A method, comprising:
receiving, by a receiver of a waveguide system comprising a processing system, electromagnetic waves having polarized modes propagating along a transmission medium;
detecting, by the waveguide system, according to an analysis of the electromagnetic waves that the transmission medium is birefringent thereby causing a differential delay between the polarized modes; and
adjusting a configuration of the receiver to mitigate the differential delay between the polarized modes, the adjusting of the configuration of the receiver comprising adjusting a position of the receiver about an outer surface of the transmission medium.

11. The method of claim 10 , wherein the adjusting of the position of the receiver comprises adjusting an azimuthal position of the receiver about the outer surface of the transmission medium.

12. The method of claim 10 , wherein the adjusting of the configuration of the receiver results in an adjustment of one or more phases of one or more corresponding components of the electromagnetic waves.

13. The method of claim 10 , wherein the receiver comprises a cross planar coupler.
