Controlling direction of LIDAR output signals

A LIDAR system, comprising:

• a LIDAR chip with a waveguide array configured to output a LIDAR output signal such that the LIDAR output signal is reflected by an object located off the LIDAR chip,
• the waveguide array includes multiple steering waveguides that each outputs a different portion of the LIDAR output signal and more than half of the steering waveguides each excludes a phase tuner;
• and
• electronics configured to tune a wavelength of the LIDAR output signal such that a direction that the LIDAR output signal travels away from the LIDAR chip changes in response to the tuning of the wavelength by the electronics.
