Case Study: Photonic Array Device Assembly
PI’s Fast Multichannel Photonic Alignment (FMPA) technology was introduced in 2016. It quickly amassed prestigious honors like the R&D 100 Award and the Lightwave Innovations Award for its revolutionary ability to perform multiple alignment processes in parallel, for example:

  • For elements whose positional optimization depends on other elements.  Examples include waveguide structures whose inputs, outputs and channels can interact, such as short waveguides whose inputs and outputs “steer” each other.  Other examples include lenses or diffractive elements in imaging or resonator assemblies whose mutual positions are interrelated.  FMPA can perform these optimizations in one go, yielding a global optimization that is often 100 times faster than previously possible.

 

  • For alignments in multiple degrees of freedom.  A ubiquitous example in Silicon Photonics (SiP) is any array device, where alignment motions in ThetaZ (common notation for rotation about the optical axis) cause dealignment in XY.  Previously, any corrective motion in ThetaZ necessitated a pause and a realignment in XY, meaning array alignments required a lot of time.  FMPA’s parallel alignment capability allows the full device alignment to be performed in one quick step, since the compensation of the geometric errors due to ThetaZ motions occurs in parallel with them......more....
