Tower Semiconductor and Xscape Photonics announced a validated prototype and a validation kit for the industry’s first monolithically integrated, optically pumped, multi-wavelength on‑chip laser source built on Tower’s PH18 silicon photonics platform. The solution supports CWDM and DWDM wavelength grids and is aimed at AI datacenter fabrics to improve bandwidth density, power efficiency, and scalability by embedding programmable multi‑color lasers on‑chip, optically pumped by a single continuous‑wave external laser. Xscape’s ChromX platform (based on CombX technology) is presented as compatible with existing modulators and detectors to simplify design and reduce component count. The release cites LightCounting projections that sales of optical transceivers and LPO/CPO for AI clusters will exceed $10 billion in 2026 and reach $20 billion by 2030. The statement includes a standard safe harbor noting forward‑looking statements are subject to risks.

Tower Semiconductor and AIStorm announced the Cheetah HS, a 120x80-pixel charge-domain imager that embeds a first-layer analog neural network and captures up to 260,000 frames per second, described as 2,000–4,000x faster than conventional CMOS sensors. The on-chip charge-domain neuron layer outputs pulse streams for downstream processing, reducing the need for expensive high-speed data converters and interfaces.
The chip includes an integrated LED driver programmable up to 40 mA, improved low-light performance, and is positioned for robotics, drones, manufacturing inspection, security tracking, biometric and sports-analysis markets. Cheetah HS is available now as a chip and in reference-camera systems.
