Title:
光ANDゲート及び波形整形装置
Document Type and Number:
Japanese Patent JP4397567
Kind Code:
B2
Abstract:
The method according to the present invention includes the steps of inputting an optical signal having a first wavelength and probe light having a second wavelength different from the first wavelength into a nonlinear optical medium, broadening the spectrum of the probe light through cross phase modulation between the optical signal and the probe light inside the nonlinear optical medium, and extracting light from the broadened spectrum of the probe having a band narrower than the band of the spectrally broadened light. According to the present invention it can be possible to provide a method and device which can easily convert the wavelength of signal light into an arbitrary wavelength in performing optical 3R functions.
