Abstract: Optical splitters and system and methods utilizing optical splitters are disclosed. The optical splitter may include an input waveguide, a free propagation region, and a plurality output waveguides. The output waveguides are connected to the free propagation region at a corresponding plurality of output ports that are positioned along a non-circular path. The output ports may be positioned such that the output waveguides have the same width.

Abstract: Various embodiments disclosed herein describe photonic passive delay lines that have a waveguide wound into a plurality of straight segments and bends. The photonic passive delay lines are configured to reduce losses from parasitic modes of light generated at the bends. Embodiments of the photonic passive delay lines vary the dimensions of the straight segments to provide different amounts of dephasing between a mode of input light received by the photonic passive delay line and one or more parasitic modes.
