Abstract: A method of manufacturing a waveguide having a combination of a binary grating structure and a blazed grating structure includes cutting a substrate off-axis, depositing a first layer on the substrate, and depositing a resist layer on the first layer. The resist layer includes a pattern. The method also includes etching the first layer in the pattern using the resist layer as a mask. The pattern includes a first region and a second region. The method further includes creating the binary grating structure in the substrate in the second region and creating the blazed grating structure in the substrate in the first region.

Abstract: Architectures are provided for selectively incoupling one or more streams of light from a multiplexed light stream into a waveguide. The multiplexed light stream can have light with different characteristics (e.g., different wavelengths and/or different polarizations). The waveguide can comprise in-coupling elements that can selectively couple one or more streams of light from the multiplexed light stream into the waveguide while transmitting one or more other streams of light from the multiplexed light stream.
