Abstract
A system and method for depolarizing optical amplifier pump sources. A pump assembly provides a pump assembly output having a polarization state that is normally depolarized. A depolarizing device receives the pump assembly output and provides an output that is depolarized irrespective of the polarization of the pump assembly output.
Claims27
An optical amplifier comprising:
- a pump assembly configured to provide a pump assembly output having a polarization state that is normally depolarized;
- and
- a depolarizing device configured to receive said pump assembly output and provide a depolarized output that is depolarized irrespective of said polarization state of said pump assembly output, said depolarized output being coupled to a fiber segment for establishing optical signal gain.
An optical communication system comprising a transmitter configured to transmit a plurality of optical signals, each at one of a plurality of wavelengths, over an optical information channel, said optical information channel comprising an optical amplifier, said amplifier comprising:
- a pump assembly configured to provide a pump assembly output having a polarization state that is normally depolarized;
- and
- a depolarizing device configured to receive said pump assembly output and provide a depolarized output that is depolarized irrespective of said polarization state of said pump assembly output, said depolarized output being coupled to a fiber segment for establishing optical signal gain.
A pump system for use in an optical communication system comprising:
- a pump assembly configured to provide a pump assembly output having a polarization state that is normally depolarized;
- and
- a depolarizing device configured to receive said pump assembly output and provide a depolarized output that is depolarized irrespective of said polarization state of said pump assembly output.
A method of pumping a fiber segment comprising:
- combining outputs of a plurality of pump sources to provide pump assembly output having a polarization state that is normally depolarized;
- depolarizing said pump assembly output to provide a depolarized output;
- and
- coupling said depolarized output to said fiber segment.
