| | Processing the optical phase information is one of the challenging technologies to realize ultrafast massive data transmission in the twenty-first century. We proposed “wave-packet engineering”, where optical phase information of femtosecond pulses is transferred to that of electronic wave packets in semiconductor devices, processed by means of nonlinear interference, and converted back to the phase modulated pulses. This paper presents novel ways to measure amplitude and phase change of femtosecond pulses through a device material by means of a Sagnac interferometer (SI) and cross-correlation Frequency Resolved Optical Gating (XFROG). |
