We present, to the best of our knowledge, the first demonstration of coherent solid-state light detection and ranging (LIDAR) using optical phased arrays in a silicon photonics platform. An integrated transmitting and receiving frequency-modulated continuous-wave circuit was initially developed and tested to confirm on-chip ranging. Simultaneous distance and velocity measurements were performed using triangular frequency modulation. Transmitting and receiving optical phased arrays were added to the system for on-chip beam collimation, and solid-state beam steering and ranging measurements using this system are shown. A cascaded optical phase shifter architecture with multiple groups was used to simplify system control and allow for a compact packaged device. This system was fabricated within a 300 mm wafer CMOS-compatible platform and paves the way for disruptive low-cost and compact LIDAR on-chip technology.
据我们所知，我们首次展示了在硅光子平台中使用光学相控阵的相干固态光探测和测距（LIDAR）。最初开发并测试了一个集成的发射和接收调频连续波电路，以确认片上测距。使用三角调频进行了距离和速度的同步测量。将发射和接收光学相控阵添加到系统中以实现片上光束准直，并展示了使用该系统进行的固态光束转向和测距测量。采用了具有多个组的级联光学移相器架构来简化系统控制，并实现紧凑封装的器件。该系统是在300毫米晶圆CMOS兼容平台上制造的，为具有颠覆性的低成本、紧凑型LIDAR片上技术铺平了道路。
