POET Technologies has announced it will showcase its advanced optical technology innovations at the upcoming OFC25 in San Francisco, highlighting its Blazar external light source (ELS) prototype and its industry-leading Teralight 1.6T optical engines optimized for AI applications and hyperscale data centers.
POET’s Blazar solution, built upon the company’s proprietary Optical Interposer platform, provides an alternative to traditional Distributed Feedback (DFB) lasers, utilizing wafer-level chip-scale packaging to significantly lower costs, enhance scalability, and improve reliability. The company says its approach addresses critical challenges in AI infrastructure by delivering cost-efficient, high-power, multi-channel optical solutions essential for co-packaged optics (CPO) and high-speed chip-to-chip communication links.
POET’s public demonstration at OFC will feature its Teralight 1.6T optical engines, developed in collaboration with Mitsubishi Electric. These engines offer an unprecedented level of integration, combining externally modulated lasers (EMLs), high-speed drivers, photo diodes, trans-impedance amplifiers (TIAs), multiplexers, and demultiplexers within a single, highly integrated optical system-on-chip design. The Teralight transmit engine uniquely incorporates Mitsubishi Electric’s 2x200G EML lasers, significantly reducing cost by using just four lasers instead of the typical eight required for conventional 1.6T transceivers. Additionally, the Optical Interposer™ technology eliminates the need for wire bonding, minimizing RF crosstalk and delivering unmatched performance. This integrated design supports both DR8 and FR4 pluggable modules on a single board architecture, simplifying development and lowering engineering complexity.
At OFC, POET’s technology will also be prominently featured in demonstrations by its key customers, including LuxshareTech, which will display 400G and 800G DR and FR modules, and Adtran (formerly ADVA), which will showcase the highly integrated Quattro 100G LR4 module. The Quattro LR4 integrates four 100G LR4 modules into a single QSFP-DD form factor, substantially enhancing port density and cost-efficiency, attracting significant interest from hyperscalers and telecommunications providers alike. Additionally, POET will exhibit its full portfolio of optical engines and light sources designed into customer-ready solutions at its booth.
POET’s Optical Interposer is a wafer-level semiconductor integration platform enabling seamless electronic and photonic device integration into a single chip.
