Optical transmission system
First Claim
1. An optical transmission system, comprising:
- an optical nonlinear element having nonlinear input/output characteristics and reproducing an optical signal;
a power detector photoelectrically converting an optical signal reproduced by said optical nonlinear element to detect a power of a specific frequency component from an obtained electrical signal; and
a variable amplifier amplifying or attenuating the optical signal inputted to said optical nonlinear element in response to a detection result by said power detector.

Abstract
An optical transmission system includes an optical nonlinear element having nonlinear input/output characteristics, a power detector detecting a power of a specific frequency component related to an optical signal reproduced by the optical nonlinear element, and a variable amplifier amplifying or attenuating the optical signal inputted to the optical nonlinear element. Evaluation of an output waveform is performed based on the power of the specific frequency component detected by the power detector, and a gain of the variable amplifier is properly controlled, so that an input power of the optical signal inputted to the optical nonlinear element can be easily set such that a good output waveform can be obtained without directly measuring the inputted or outputted optical signal.
