+/-45° Beam Steering, 2° angular resolution, 64 individually controllable channels
MCAE102-940 is a metasurface beam steerer that boasts exceptional performance, with +/-45° optical deflection angle and less than 1mA quiescent current consumption, making it the perfect beam steering device for near infrared sensing applications.
The device uses metasurface technology which uses subwavelength nano structures (pixel) to change the phase of the incident light. In this device, a novel electrically controllable meta pixel is introduced, and the phase of the incident light can be controlled by applying different voltages on each pixel. The pixels with different phases are arranged such that the far field wavefront is steered to different directions.
The device works with MCAD0641 Optical Phased Array Driver. It comes with different active areas for different applications.
