Abstract
Method and apparatus for generating pulses in a light detection and ranging (LiDAR) system. In some embodiments, a resonance chamber is provided to recirculate electromagnetic radiation from a light source between a base mirror and an active laminated structure characterized as a Bragg grating structure and having interleaved passive and active layers. A Q-switch control circuit applies a voltage profile to the active layers to transition the active laminated structure between a charging state in which the electromagnetic radiation recirculates within the resonance chamber and a release state in which the electromagnetic radiation is transmitted through the active laminated structure as an emitted light pulse. The passive layers may be formed of a dielectric material. The active layers may be formed of a metal material such but not limited to Indium Tin Oxide (ITO), Lithium Niobate (LiNbO3), Barium Titanate (BaTiO3), doped Silicon (Si), or doped Germanium (Ge).
