An integrated phased array transmitter chip that uses an electronically controlled photonic network for millimeter-wave generation and beam formation is developed and used to demonstrate a fiber to
The phased array antenna system includes a plurality of antenna elements and one or more low noise amplifiers (LNAs) encapsulated in a fiber such as flexible polyetherimide (PEI) fiber...
In this article, we presented a cascaded internal phase control method to expand the internal all-fiber phased array. The method distributes the phase
The invention details a flexible thermally drawn receive phased array antenna system constructed using polyetherimide (PEI) fiber material to enhance pliability and durability.
In this article, we presented a cascaded internal phase control method to expand the internal all-fiber phased array. The method distributes the phase measurements to a series of
Depending on usage, an FPGA can consume up to tens of watts of power, creating thermal issues and likely requiring bulky heat sinks or other advanced cooling methods. Instead, a preferred architecture

High spatial resolution typically requires a large number of phase channels. In this paper, we propose and demonstrate a high-resolution wavelength-scanning multimode fiber imaging system, enabled by
We present a multi-beam optical fiber phased array (OPA) with simultaneous light detection and ranging (LiDAR) and free-space optical communication (FSO) data transmission functions. The
Here, we report an integrated photonic-assisted phased array transmitter applicable for low-power, compact radio heads in fiber to mm-wave fronthaul links.
This paper proposes a delay line (DL) based on a few-mode fiber (FMF) mode interferometer utilizing few-mode long-period fiber grating (FM-LPFG), and constructs a 1 × 4 phased
