Patent number: 11733583Abstract: An optical beam steering device may include a tunable laser diode configured to emit laser beams and an antenna that includes a grating structure and is configured to convert the laser beams to a linear light source based on the grating structure. The tunable laser diode may emit a first laser beam having a first wavelength, and emit a second laser beam having a second wavelength, the second wavelength different from the first wavelength. The antenna may receive the first laser beam and, in response, output a first linear light source having a first emission angle with a surface of the antenna. The antenna may further receive the second laser beam and, in response, output a second linear light source having a second emission angle with the surface of the antenna, the second emission angle different from the first angle.Type: GrantFiled: July 20, 2021Date of Patent: August 22, 2023Assignee: Samsung Electronics Co., Ltd.Inventors: Dong Jae Shin, Seong Gu Kim, Yong Hwack Shin, Chang Gyun Shin, Dong Sik Shim, Chang Bum Lee, Jung Ho Cha, Kyoung Ho Ha
