Multimode silicon photonics is attracting more and more attention because the introduction
of higher-order modes makes it possible to increase the channel number for data …

Integrated optical phased arrays can be used for beam sha** 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 …

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 …

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 …

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 …

To prevent the crosstalk between adjacent waveguides in photonic integrated circuits, the
minimum thickness of the cladding layers is around half a wavelength, which imposes a …
