Directional Couplers for multi-ring filters

[lukasc-ubc]

A request to implement a Layout PCell + CML for a fully-parameterized directional coupler with the following parameters:

• g: gap
• r1: Radius 1
• r2: Radius 2
• w: Waveguide width
• Lc: Coupling length
• pol: 'TE' or 'TM'; for use in INTERCONNECT calling FDTD to simulate one of these if pol is defined, or simulate both if undefined.
• wavelength: default 1550. Consider a simulation bandwidth of 10% of the central wavelength. Used by the INTERCONNECT-FDTD simulation.
