Partow waveguide technology is based on thin films of lithium niobate that are bonded and transferred to a silicon or quartz substrate. A rib layer is directly etched on top of the electro-optic thin film layer to form the optical waveguide. The high index contrast waveguide has sub-micron mode size which requires grating couplers for coupling to the device. This high index contrast platform allows to make advanced photonic components such as micro-ring modulators. Partow is developing these devices.
