Abstract: In some implementations, an optical interference filter includes a substrate; and a set of layers that are disposed on the substrate. The set of layers includes a first subset of layers, wherein the first subset of layers comprises an aluminum nitride (AlN) material, and wherein a stress of the first subset of layers is between −1000 and 800 megapascals; and a second subset of layers, wherein the second subset of layers comprises at least one other material.

Abstract: An optical interference filter includes one or more sets of layers. Each set of layers includes a first layer that includes at least aluminum and nitrogen (e.g., an aluminum nitride (AlN) material), a second layer that includes at least silicon and oxygen (e.g., a silicon dioxide (SiO2) material), and a third layer that includes at least hydrogen and silicon (e.g., a hydrogenated silicon (Si:H) material). The second layer is disposed between the first layer and the third layer.

Abstract: An optical filter having a passband at least partially overlapping with a wavelength range of 800 nm to 1100 nm is provided. The optical filter includes a filter stack formed of hydrogenated silicon layers and lower-refractive index layers stacked in alternation. The hydrogenated silicon layers each have a refractive index of greater than 3 over the wavelength range of 800 nm to 1100 nm and an extinction coefficient of less than 0.0005 over the wavelength range of 800 nm to 1100 nm.
