Micro-Electro-Mechanical Systems (MEMS) Quantum Optical Routing

Dynamic optical path reconfiguration using 3D MEMS mirror arrays to route single photons without optical-electrical-optical (OEO) conversion.

Transparent Photonic Switching Without Photon Interruption

Classical routers convert photons to electrical bits to read packet headers, an operation that collapses quantum states. 3D MEMS matrix switches steer collimated light beams using electrostatically tilted micro-mirrors, offering insertion loss below 1.2 dB and polarization-dependent loss under 0.05 dB.

Sub-10 Millisecond Fast Optical Protection Switching

When optical time-domain reflectometry (OTDR) detects fiber backscatter anomalies indicating tapping or damage, the node controller tilts the MEMS mirrors within 8 milliseconds, rerouting the quantum channel across redundant geometric ring paths without terminating active QKD sessions.
