Lightwave Logic (LWLG) shares were already on fire Wednesday, climbing more than 15% to settle at $5.02 — marking the stock’s strongest performance in over five months. But Thursday morning brought even more excitement.

Lightwave Logic, Inc., LWLG

The semiconductor technology firm unveiled a development partnership with Tower Semiconductor (TSEM), triggering an immediate market reaction. LWLG shares rocketed up to 30% during premarket hours.

The agreement focuses on incorporating Lightwave Logic’s electro-optic polymer modulator technology into Tower’s PH18 silicon photonics process design kit (PDK). These advanced modulator designs are engineered for bandwidths exceeding 110 gigahertz.

This performance range positions the technology as a strong contender for 400-gigabits-per-lane capabilities within photonic integrated circuits — precisely the high-bandwidth data transmission solutions demanded by modern AI data center operations.

The partnership goes beyond preliminary discussions. Engineering tapeouts scheduled for 2026 will provide customers opportunities to test and validate modulator-based designs using the PH18 platform.

Understanding the Technology

The initiative will test low-power consumption 200G and 400G modulator configurations designed for artificial intelligence infrastructure, high-performance computing environments, and next-generation networking architectures.

Tower Semiconductor shares also responded positively, advancing nearly 2% in premarket activity after the partnership announcement.

Expanding Partnership Network

Lightwave Logic has been busy forging strategic alliances beyond this Tower Semiconductor arrangement. Earlier this month, the company revealed that its electro-optic polymer modulator technology was being integrated into Luceda Photonics’ design platform, specifically for SilTerra Malaysia’s silicon photonics capabilities.

That arrangement enables engineers to create and tape out photonic integrated circuits incorporating LWLG’s modulators for 200G and 400G per lane performance. An initial tapeout involving SilTerra, Lightwave Logic, and Luceda Photonics was completed recently.

Testing and performance verification from that initial tapeout is anticipated around mid-2026.

Meanwhile, Tower Semiconductor’s collaboration with LWLG follows its February disclosure of working with Nvidia to produce 1.6 terabits-per-second optical modules designed for AI data center applications using its silicon photonics technology.

Tower is strategically expanding its AI infrastructure presence, and this Lightwave Logic collaboration aligns with that broader strategy.

LWLG finished Wednesday’s session at $5.02. TSEM shares gained nearly 2% during Thursday’s premarket trading following the partnership disclosure.
