Photonic true time delay
Buckeye Photonics replaces electronic phase shifters with optical true time delay, so every frequency across a wide band points to the same angle. Squint-free, wideband, and massively parallel.

The problem
Phased arrays steer radar and satellite-communications beams electronically, with no moving parts and instant repointing. Nearly all of them steer with phase shifters. A fixed phase shift points the beam correctly at only one frequency, so across a wide band the beam squints and points in different directions at different frequencies.
Steer angle drifts with frequency. The wider the band, the worse the pointing error.
Phase shifting forces a choice. Go narrowband, or give up scan angle. You cannot keep both.
That ceiling bites hardest where wide instantaneous bandwidth and scan angle are needed at once: wideband radar and electronic warfare, multi-band satellite communications, and counter-UAS radar.
Our approach
True time delay steers by delaying the signal rather than shifting its phase, so every frequency points to the same angle. Squint is removed by physics, not corrected after the fact. Buckeye implements it optically with the Fourier Cell architecture: a compact, scalable beamformer that holds its beam across multi-octave bandwidth.
The optical beamformer feeds a conventional AESA aperture: antennas, LNAs, GaN amplifiers, and a digital back-end. The photonics is the beamformer layer only, not a fully photonic system.
One beam held steady across a wide instantaneous band, exactly where phase-shift arrays are forced to trade bandwidth against scan angle.
Optical routing carries every element's channel at once, forming many beams independently and simultaneously in one apparatus.
The opportunity
The beamformer is the layer Buckeye supplies, roughly a third of AESA system cost. Read the ladder as a narrowing: from the systems our subsystem rides in, down to the serviceable market we sell into.
Wideband search and track, where squint-free steering keeps pointing accurate across the full band.

Per-vertical figures are the 2029 breakdown of the $780M serviceable beamformer SAM.

Beamformer share is roughly 33%+ of AESA system cost (Cyient). Wideband-relevant and phased-array-addressable fractions are Buckeye structural estimates, not analyst figures.
Where we stand
Buckeye acquired the original White Cell optical beamformer prototype, Dr. Anderson's OTTD architecture demonstrated to TRL-6. It is the workhorse the team is restoring and integrating with an antenna aperture to prove optical true time delay in live RF. The next-generation Fourier Cell is the production beamformer that follows.
