Lu et al continues investigation into graphene integrated into waveguides and tuning the absorption with chemical potential.First they solved for TM modes of graphene on a 250 by 600 nm silicon waveguide with a 7 nm $AL_2O_3$ buffer operating at a wavelength of $1.53 \mu m$. Attenuation is $0.134 \frac{dB}{\mu m}$ for $\mu_c=0$ and $0.044 \frac{dB}{\mu m}$ at $\mu_c=\mu_t$ where $\mu_t$ is the transition chemical potential from before. Absorption can be continued to be reduced when $\mu_t$ is increased.
