Abstract
A head-up display, such as found in smart glasses, may include a light source configured to project light for display. A heads-up display may include a polymer aerogel optical waveguide configured to receive the light from the light source, guide the received light to an area in front of an eye of a user, and project the light to the eye of the user. The polymer aerogel optical waveguide can include a core portion made from a glass having a relatively high index of refraction and a cladding portion made from a polymer aerogel having a relatively low index of refraction so that light is guided in the core portion by total internal reflection at an interface between the core portion and the cladding portion.
