Optical true time delay for phased-array antennas: demonstration of a quadratic White cell.
نویسندگان
چکیده
We have demonstrated a proof-of-concept optical device that can produce true time delays for a phased-array radar. This device combines White cells of differing lengths with a spatial light modulator to select between the paths on multiple bounces of a given beam. The approach can handle thousands of light beams and produce hundreds of different delays. The number of delays is proportional to the square of the number of bounces.

Demonstration of a linear optical true-time delay device by use of a microelectromechanical mirror array.
We present the design and proof-of-concept demonstration of an optical device capable of producing true-time delay(s) (TTD)(s) for phased array antennas. This TTD device uses a free-space approach consisting of a single microelectromechanical systems (MEMS) mirror array in a multiple reflection spherical mirror configuration based on the White cell. Divergence is avoided by periodic refocusing ...
متن کاملRecirculating photonic filter: a wavelength-selective time delay for phased-array antennas and wavelength code-division multiple access.
A novel wavelength-selective photonic time-delay filter is proposed and demonstrated. The device consists of an optical phased-array waveguide grating in a recirculating feedback configuration. It can function as a true-time-delay generator for squint-free beam steering in optically controlled phased-array antennas and as an encoding-decoding filter for wavelength code-division multiple access.
متن کاملPolynomial-based optical true-time delay devices with microelectromechanical mirror arrays.
We previously reported optical true-time delay devices, based on the White cell, to support phased-array radars. In particular, we demonstrated a quadratic device, in which the number of delays obtainable was proportional to the square of the number of times the light beam bounced in the cell. Here we consider the possibilities when a microelectromechanical (MEM) tip/tilt mirror array with mult...
متن کاملA K-band phased array antenna system employing photonic true-time delay module
A novel 1-to-64 (6-bit (2 6 )) optical true-time delay module that can provide linear time delays ranging from 0 to 443.03 picoseconds is presented. The bandwidth of the fully packaged module is determined to be as high as 539 GHz. This true-time delay module is employed to control an eight-element K-band phased array antenna system. Far field patterns covering 18 GHz to 26.5 GHz are measured a...
متن کاملOpto-VLSI-based photonic true-time delay architecture for broadband adaptive nulling in phased array antennas.
This paper proposes a novel Opto-VLSI-based tunable true-time delay generation unit for adaptively steering the nulls of microwave phased array antennas. Arbitrary single or multiple true-time delays can simultaneously be synthesized for each antenna element by slicing an RF-modulated broadband optical source and routing specific sliced wavebands through an Opto-VLSI processor to a high-dispers...
