Disclosed herein are an apparatus and method for analyzing malicious code in a multi-core environment. The apparatus for analyzing malicious code includes a core setting unit for setting at least one monitoring core, on which malicious code is to be monitored, among cores of a multi-core Central Processing Unit (CPU), and executing a monitoring program on the monitoring core, a behavioral information collection unit for, when execution cores that are not set as the monitoring core execute analysis target code, collecting pieces of behavioral information using the monitoring program and a hardware debugging device, and a storage unit for storing the behavioral information.

An optical wavelength converter based on cross-gain modulation with wide input dynamic range, the converter including a semiconductor optical amplifier, a continuous wave source, and a probe beam controller. The semiconductor optical amplifier modulates probe power on the basis of pump power. The continuous wave source generates the probe beam and supplies the generated probe beam to the semiconductor optical amplifier. The probe beam controller adjusts bias current supplied to the continuous wave source and controls the probe power in proportion to the pump power.
