The photonic engine for AI scale-out
Ultra-compact lithium niobate modulation
Data transfers need modulators to control light
Demands for increased speed and energy efficiency call for solutions beyond the materials that enable today’s photonic interconnects.
If miniaturized and efficiently fabricated, lithium niobate’s material properties can enable faster, more efficient data transfers and, in the longer term, quantum communications.
LiNPhA aims to provide an upgrade path for the photonic industry by miniaturizing lithium niobate modulators into their most compact form, designed for hybrid integration with existing silicon workflows.
Using lithium niobate to deliver:
Ultra compact modulation
TFLN state-of-the-art efficiency and speed, in a 10x smaller footprint, to meet frontier demands in datacenter interconnectivity, display, and free space optic applications
Low-loss modulation
Indirect active feedback for unmatched signal-to-noise, without altering the state of light for quantum applications
Technology empowered by:
Lithographic periodic poling
CMOS-compatible, sub-µm precision process technology unlocking fabrication of nonlinear applications at scale
Bulk coupon sourcing
Leveraging MEMS technology to source coupons directly from bulk materials, enabling more efficient sourcing as well as modulation at higher power than TFLN
