PIC Characterization
Home »
Alter Technology is actively involved in the field of Photonic Integrated Circuits (PICs), especially for high-reliability sectors like aerospace, defense, and telecommunications. Our work typically includes:
Design and Prototyping Support
We collaborate with developers to ensure PICs meet stringent performance and environmental requirements.
Testing and Qualification
Alter provides advanced testing services, including optical characterization, thermal cycling, and radiation testing—crucial for space and harsh environments.
Packaging and Assembly
We offer specialized packaging solutions for PICs, ensuring optical alignment, thermal management, and mechanical robustness.
Reliability Assessment
Long-term reliability testing under extreme conditions is a key part of our offering, helping to validate PICs for mission-critical applications.
Our expertise bridges the gap between cutting-edge photonics research and real-world deployment in demanding environments.
Alter Technology is making significant strides in quantum photonics, especially in the context of space and high-reliability applications. Here’s a snapshot of their key activities:
Quantum Key Distribution (QKD) for Space
Alter is leading the development of a compact and robust quantum photonic transceiver for secure satellite communications. This system uses entangled photons and faint laser pulses to implement protocols like BB84 and E91, enabling unbreakable encryption for space-based links.
Quantum Photonic Integrated Circuit Packaging (QPICPAC)
We’re part of a UK-based consortium working on scalable packaging solutions for Quantum Photonic Integrated Circuits (QPICs). These circuits are essential for miniaturizing and mass-producing quantum technologies, and Alter’s role focuses on making the packaging process more efficient and cost-effective.
Advanced Quantum Projects
Alter is also involved in a range of R&D efforts—like QUEST, SLAM, and rAmpart—exploring applications such as quantum processors, ion trap-based atomic clocks, MEMS gravimeters, and single-photon detectors.
Our work is helping bridge the gap between cutting-edge quantum research and real-world deployment, especially in environments where precision, reliability, and miniaturization are critical.
