The scientific community has witnessed tremendous expansion of research on layered (i.e. two-dimensional, 2D) materials, with increasing recent focus applications to photonics. Layered materials are particularly exciting for manipulating light in the confined geometry photonic integrated circuits, where key material properties include strong and controllable light-matter interaction, limited optical loss. feature tunable properties, phases that promising electro-optics, a panoply polymorphs suggest rich design space highly-nonperturbative devices based phase-change functionality. All these features manifest band gap above photonics-relevant near-infrared (NIR) spectral ($\sim$ 0.5 - 1 eV), meaning they can be harnessed refractive non-absorptive) applications.
