Abstract
The present invention relates to a light phased array antenna and a Light Detection and Ranging (LiDAR) including the same. The present invention provides a light phased array antenna including: a light distributing unit configured to receive light from a laser generator and distribute the received light to a plurality of antenna element waveguides; a phase modulating unit configured to modulate a phase of light propagated through the antenna element waveguides by applying an electric field to the plurality of antenna element waveguides; and a light output unit configured to output light modulated in the phase modulating unit, in which the light distributing unit, the phase modulating unit, and the light output unit include a base part and an optical waveguide provided on the base part and including the plurality of antenna element waveguides, and a LiDAR including the same.
