2D Photonics is a company that designs, develops, and manufactures next-generation photonic circuits for telecom and datacom applications. Their technology integrates graphene into photonics to create ultra-high bandwidth, low latency optical interconnects that reduce cost and energy consumption, particularly for generative AI, cellular, and strategic data transfer. Their solutions offer high bandwidth density, wavelength independence across O, C, and L bands, low power consumption with uncooled operation, and compatibility with silicon foundry manufacturing processes. This positions them as a scalable, high-performance provider of energy-efficient optical transceiver solutions addressing the growing demand for data traffic in AI, data centers, and mobile communications.
