Linq Photonics – Chip-Level Integrated Photonic Light Modulators that Split a Laser into 3X more Channels than Current Solutions

Linq Photonics develops compact, high-performance photonic components for quantum computing, optical satellite communication, and space applications. These systems require precise and stable electro-optic laser modulation for laser control, timing, encoding, and communication. Unlike conventional bulky optical setups, Linq’s chip-integrated photonic modulators provide three times more channels while using only 10% of the space. Their alignment-free design offers exceptional stability and reliable operation in cryogenic, vacuum, and thermally demanding environments.

Benefits:

• Integrated photonic electro-optic modulation units that enable parallel, high-extinction-ratio and high-speed optical control in a compact and mechanically robust form factor, specifically designed for space-relevant applications.
• Replacement of complex free-space optical assemblies with compact thin-film lithium niobate (TFLN) photonic integrated circuits (PICs).
• High-speed, multi-channel modulation within a single robust subsystem, providing alignment-free operation and mechanical stability, which is ideal for cryogenic, vacuum, and thermally dynamic environments.
• The wavelength is flexible (primarily 1550 nm) and it supports satellite communications, quantum sensing and metrology.
• Reduces SWaP, improves long-term operational stability, and enables the parallel operation of multiple optical channels within one hardware platform.
