Nonlinear optics involves a non-proportional response of material to light. One of the applications is a laser pointer, which is actually invisible but is converted to a visible green or red light by nonlinear response of the material.
MEMS (Micro Electro Mechanical Systems). one such system is an array of many tiny mirrors that deflect light in a computer projector to form a power point presentation. Optics is primarily concerned with Photonic MEMS, such as when the mechanical degree of freedom affects the properties of an optical device via the pressure applied by light.
