Abstract: An optical element may include a substrate. The optical element may include a first anti-reflectance structure for a particular wavelength range formed on the substrate. The optical element may include at least one layer disposed on a portion of the first anti-reflectance structure. The optical element may include a second anti-reflectance structure for the particular wavelength range formed on the at least one layer. A depth between a first surface of the first anti-reflectance structure and a second surface of the second anti-reflectance structure, a first index of refraction of the first anti-reflectance structure, a second index of refraction of the second anti-reflectance structure, and a third index of refraction of the at least one layer may be selected to form a diffractive optical element associated with a particular phase delay for the particular wavelength.

Abstract: A micro-sized optical device may comprise a mirror suspended on a set of hinges that are mounted to the substrate and that are configured to tilt the mirror about an axis, wherein a hinge of the set of hinges is a two-layer structure with a pivot point that aligns with a mass center of the mirror; and a three-layer comb actuator structure associated with the hinge of the set of hinges, wherein the three-layer comb actuator structure includes a rotor comb actuator, a first stator comb actuator, and a second stator comb actuator.

Abstract: A diffractive optical element may include sub-wavelength period stack-and-gap structured layers providing transmissive phase delay at a wavelength. The sub-wavelength period stack-and-gap structured layers may include a set of thin anti-reflection layers that are index matched to an environment or a substrate over a range of fill factors of the sub-wavelength period.

Abstract: A micro-electro-mechanical system (MEMS) device may comprise a first layer that includes a stator comb actuator; a second layer that includes a rotor comb actuator; a mirror structure that includes a mirror; and a first set of hinges and a second set of hinges configured to tilt the mirror structure about a first axis of the MEMS device based on a driving torque caused by the stator comb actuator engaging with the rotor comb actuator. The first set of hinges may be configured to resist a lateral linear force on the mirror structure in a direction associated with the first axis caused by the stator comb actuator engaging with the rotor comb actuator. The second set of hinges may be configured to resist an in-plane torque on the mirror structure about a second axis of the MEMS device caused by the stator comb actuator engaging with the rotor comb actuator.
