AB The development of the Photonic Integrated Circuits (PIC) enables promising technologies to become available. One of these promising technologies is the LiDAR onchip for high precision distance measurement. The advantages of making the LiDAR onchip are the smaller footprint and the large scale fabrication capacity which leads to the reduction of manufacturing cost per system. PIC LiDARs rely on Optical Phased Arrays (OPA) for beam shaping and beam steering. Steering in Optical Phased Arrays is achieved by applying a gradual phase change on each emitter element. The phase change is made by thermo (for Silicon technology) or electro (for InP) optic modulation. This can dramatically increase the complexity of the device and also make it difficult for the future characterization. In this thesis is a new LiDAR concept based on tilted grating couplers is presented. This LiDAR does not require any phase modulators for shifting the beam, and can be integrated on any photonic technology platform.
