Waveguide Splitters

Simple waveguide splitters. These consist of a generic (non-optimized) 1x2 Y-splitter geometry.

WgYSplitter Y-splitter PCell with branches that fan out specifiable angle.
WgYCombiner Y-Combiner PCell with branches that fan out specifiable angle.
WgY90Splitter Y-splitter PCell with branches that fan out at right angles to the input waveguide.
WgY90Combiner Y-shaped combiner with branches that come in at right angles to the output waveguide.
WgY180Splitter Y-splitter PCell with branches that fan out at right angles to the input waveguide and then come back to the horizomtal direction.
WgY180Combiner Y-shaped combiner with branches that come in horizontally and combine with the output waveguide at right angles.
