Integrated optical phased arrays can be used for beam shaping and steering with a small
footprint, lightweight, high mechanical stability, low price, and high-yield, benefiting from the …

Optical phased arrays (OPAs), the optical counterpart of phased arrays at radio frequencies,
can electronically steer an optical beam without any moving parts. To achieve a 180° field of …

This paper reports on large field-of-regard, high-efficiency, and large aperture active optical
phased arrays (OPAs) for optical beam steering in LIDAR systems. The fabricated 5 mm …

Ultra-compact, densely integrated optical components manufactured on a CMOS-foundry
platform are highly desirable for optical information processing and electronic-photonic co …

We analyze optical phased arrays with aperiodic pitch and element-to-element spacing
greater than one wavelength at channel counts exceeding hundreds of elements. We …

The ability to control and steer optical beams is critical for emerging technologies. Among
these are light detection and ranging (LiDAR), laser display, free space communication, and …

Mode‐division multiplexing (MDM) is attractive to enhance the link capacity of optical
interconnects by using multiple mode‐channels in multimode bus waveguides. As sharp …

Electromagnetic coupling is ubiquitous in photonic systems and transfers optical signals
from one device to the other, creating crosstalk between devices. While this allows the …

Mode-division multiplexing (MDM) technology has drawn tremendous attention for its ability
to expand the link capacity within a single-wavelength carrier, paving the way for large-scale …
