発明の名称 (英語) Ultrabroad-band variable-wavelength wavelength-multiplexed pulse waveform shaping device
発明の概要(英語) An ultra-broadband, variable and multiple wavelength, waveform shaping apparatus is disclosed that excels with the ability to yield light pulses shaped in waveform, variable and multiple in wavelength over an ultra-broad bandwidth, the pulses being as short as in the order of pico-seconds or less, or even in the order of femto-seconds. The apparatus includes a light source (21) for a light pulse, an ultra-broadband light pulse generating unit (22) for producing from a light pulse, an ultra-broadband light pulse beam, a beam expander (24) for spatially expanding the beam in one direction (along the y-axis) in its cross section, and a wavelength dispersive unit (26) for dispersing wavelengths of light beam pulse while further spatially expanding the expanded beam along the x-axis, a two-dimensional spatial amplitude modulator (11) for selecting wavelength bands varying in center frequency along the y-axis, a two-dimensional space phase amplifier (12) for modulating a plurality of lights selected by wavelengths into different phases, and a beam reducing and waveform shaping unit (28) for reducing so phase modulated light beam pulse components along the x-axis while shaping them into desired waveforms, whereby multiple wavelength light pulses are formed, which have center their wavelengths varying along the y-axis and waveforms shaped independently of each other and as desired.
