Medusa™ Fiber µlens Array
High-density, laser-welded, fiber-optic arrays for precision and robustness
Medusa™ fiberized microlens arrays offer nearly limitless scaling for fiber interconnects that cannot be matched by competing technologies. Laser-welded fibers ensure robust adhesion and 100% fused silica beam path, while automated alignment guarantees performance specifications regardless of fiber type.
Dense-packing with configurable placement
Medusa™ fiberized microlens arrays can be pre-configured to provide any fiber density any location for any type of fiber, including mixed fiber types. Epoxy-free path provides uninterrupted silica path for high reliability applications such as datacenter interconnects, silicon photonics interconnects, or kW-per-fiber beam combination.
Technical specifications
The preliminary specifications of Medusa™ fiberized microlens arrays are given below:
- Fiber type: SM, PM, MM, LMA, or mixed
- Number of fibers: 128, or user defined to over 1024
- Fiber configuration: hex-pack, square pack, or user defined
- Center-to-center spacing: user defined ≤ 250µm
- Pointing error: ≤ 2.5mrad
- PM fiber co-alignment: ≤0.3°
- Connector loss per channel: 0.5/1.6dB (avg/max)
Manufacturing features of Medusa™ fiberized microlens arrays make them suitable for integration into high-density expanded-beam connectors. Such features include:
- Bar-coded fibers for easy correlation to microlens location
- Mounted or unmounted microlens array
- Epoxy filled (not in path) for hermetic strain-relief
