3D schematic drawing of the presented serpentine OPA design. Grating antennas, phase shifters, and the additional lengths between two serpentine sections are circled in green, white, and black, ...

STRL is promoting research on optical phased arrays *1 that can control the direction of a light ray at high speed by applying voltage, toward the realization of AR glasses capable of viewing natural ...

A new phase shifter does not need clean-room facilities for fabrication, so is inexpensive to manufacture. The liquid-metal enabled phase shifting elements have a 'passive' nature, unlike the 'active' ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

We are conducting research on holographic display basic technologies and two-dimensional deflection optical phased arrays (OPA) for spatial image reproduction displays that will be able to present ...

Phased array technology is far from new. Phased-array antennas have been used for decades in a variety of military applications. Now, however, their use in 5G systems in the Band 2 frequency range is ...
