100 Gbit/s optical signal eye-diagram measurementwith optical sampling using organic nonlinear optical crystal

Abstract

The eye diagram of a 100 Gbit/s optical signal has been successfully measured using sum-frequency-generation optical sampling, which uses an organic crystal (AANP: 2-adamantylamino-5-nitropyridine) with high optical nonlinearity to improve the signal-to-noise ratio of the measured waveform. Using this method, a signal-to-noise ratio > 17 dB is obtained at a signal peak power of 270 mW.
