Summary:Provided are an optical waveform shaping apparatus and an optical waveform shaping method. According to an embodiment, the optical waveform shaping apparatus includes a multiplexer/demultiplexer (D/MUX) unit demultiplexing an optical signal in which optical signals of a plurality of wavelengths are multiplexed, a micro lens system refracting the demultiplexed optical signal into a collimated beam of light, and a wavelength level controller unit shaping a waveform of the optical signal. The wavelength level controller unit includes a 2D LCoS for adjusting and reflecting an amplitude or a phase value of the demultiplexed optical signal to have a distribution that is desired for each cell, and a controller for controlling the distribution.
