Collimation and coupling of fibers can be made simple with the use of a PowerPhotonic fiber microlens array. PowerPhotonic standard microlens arrays are designed for coupling or collimation of SMF-28 single mode fibers.

Multi-channel optical communication systems require microlens arrays for coupling between laser sources, fiber and waveguide arrays, optical multiplexing and optical switching.

Made from fused silica, these microlens arrays minimise channel cross-talk due to extremely low scatter and minimise insertion loss due to surface accuracy.
