Design and Analysis of Ultralow Voltage Graphene on the Silicon Rich Nitride Tunable Ring Resonator-Based Add-Drop Filter for DWDM Systems

<div>Simulated bending loss as a function of bending radius for TE and TM modes from 6 to 37.5 <i>μ</i>m. At a radius of 6 <i>μ</i>m, all the mode power radiates from the core. At 37.5 <i>μ</i>m, losses are quite similar to those in a straight waveguide. Modes were calculated at a wavelength of 1570 nm. TM mode profiles are included in the figure for bending radii of 6 and 37.5 <i>μ</i>m .</div>
