Abstract: Provided are a semiconductor optical amplifier and an optical signal processing method using the same. The reflective semiconductor optical amplifier includes: an optical signal amplification region operating to allow a downward optical signal incident from the external to obtain a gain; and an optical signal modulation region connected to the optical signal amplification region and generating a modulated optical signal. The downward optical signal is amplified through a cross gain modulation using the modulated optical signal and is outputted as an upward optical signal.

Abstract: Provided is a frequency-tunable terahertz light source device. The frequency-tunable terahertz light source device satisfies a Littrow diffraction condition at a wavelength and simultaneously satisfies a Littman-Metcalf diffraction condition at another wavelength using a double diffraction grating having two grating periods. Thus, oscillations simultaneously occur at the two different wavelengths, such that a terahertz wave can be stably generated by beating of the two oscillation wavelengths. In addition, the frequency-tunable terahertz light source device can readily change a frequency up to several terahertz and can be fabricated in a small size.

The apparatus includes: a wavelength converter receiving a pump beam having input information and a probe beam having a different wavelength from the pump beam, and outputting the pump beam with an overshoot shifted to a red wavelength and an undershoot shifted to a blue wavelength due to non-linear characteristics and self-phase modulation of semiconductor optical amplifiers (SOAs) and the probe beam delivered the input information from the pump beam; an optical divider dividing output paths of the probe beam to which the input information has been delivered and the pump beam having the overshoot and the undershoot; a converted-wavelength extractor filtering the probe beam received from the optical divider; and a clock data regenerator obtaining a pseudo return-to-zero (PRZ) signal from the pump beam received from the optical divider and extracting a clock signal from the PRZ signal.The apparatus and method can simultaneously perform wavelength conversion and optical clock signal extraction on an NRZ signal using an optical method, without converting the NRZ signal into an electrical signal.

Abstract: Provided is a signal processor for converting a signal that converts a return to zero (RZ) signal into a non-return to zero (NRZ) signal, in which two 2R (re-amplifying, re-shaping) regenerators are connected in parallel between an input waveguide and an output waveguide with different lengths from each other. The 2R regenerator includes: two semiconductor optical amplifiers having different lengths from each other; and phase control means connected to a short semiconductor optical amplifier. The RZ signal input by a length difference of the waveguide is delayed by a time difference of a half of one bit so that the 2R regenerated NRZ signal can be obtained.
