two-dimensional), nor does it require a separate "polarization-splitting element," nor does it specify whether the coupling of the two polarization states must occur simultaneously or may occur sequentially

Sundaram opines that because the preferred embodiment in the '847 Patent specification describes an arrayed waveguide grating ("AWG"), the claim term "waveguide multiplexer" must be limited to AWG architectures

The '015 Patent specification uses the phrase "capable of coupling light of two orthogonal polarization states" without specifying whether such coupling must occur simultaneously or may occur sequentially
