摘要：
A structure of optical arbitrary waveform generation(OAWG) based on an array of tunable apodized waveguide Bragg gratings(WBGs) is proposed. The WBGs array on lithium niobate(LN) consists of several apodized gratings, waveguides and electrodes deposited on both sides of gratings and waveguides. The properties of OAWG are analyzed using transfer matrix method. Due to the electro-optic effect of LN, the amplitude and phase of incident light source are controlled via adjusting the voltages on electrodes. Consequently, the optical pulses with different waveforms are obtained and the amplitude is linearly tuned. In addition, voltages compensating amplitude and phase distortion are demonstrated.
