Novel on-chip double slot high-k waveguide grating couplers have been successfully fabricated, and characterized. Silicon cannot yet be directly used for light generation and modulation in photonic devices because of its weak nonlinear optical effects. Slot waveguide is a solution to this problem, this structure consists of silicon and low refractive index material layers as the active material[1, 2]. Previously, grating couplers were demonstrated for horizontal single slot SiO 2 waveguides [3, 4]. Double slot waveguide is of great interest since the confinement of the optical power in the active material is significantly larger. Atomic layer deposited (ALD) high-k aluminum oxide (Al 2O 3) was used as the slot layer because of a superior layer quality and thickness uniformity. The ultimate goal of this work is the demonstration of the highly reproducible on-chip photonic devices.
