Heterodyne optical spectrum analyzer with provisions for intensity noise subtraction |
摘要 |
<p>A coherent optical spectrum analyzer is provided in which an optical balancing tone having a specific signature is injected into a signal path of a balanced optical receiver. A measuring unit is provided to analyze the balancing tone component in the signal output from the balanced optical receiver and determine characteristics of the optical receiver. A compensation unit is provided for providing compensation to counter, or negate any imbalances determined via the measuring unit. The balanced optical receiver is preferably a polarization state independent optical receiver. <IMAGE></p> |
