In depth study of optical behavior of a novel leaky waveguide deflector
Résumé
This article presents a detailed study of the optical behavior of a leaky waveguide deflector in view of its utilization as key component to create a new solution for an analog to digital converter, capable to achieve very high data conversion rate (up to 40 giga sample per second). We present here the different works that we went through using software based on BPM (Beam Propagation Method) and FDTD (Finite Difference Time Domain) to determine the phase and amplitude characteristics of the leaky optical field. These pieces of information are indispensable to design of a diffractive optical lens to focus the leaky beam. As the results between theory and simulation are in good agreement, the next steps are to realize and finalize the component.
