Light-emitting devices and/or systems are described. In some embodiments, light-emitting devices and/or systems can recycle at least some light generated by a light-generating region of the light-emitting device. In one embodiment, a light-emitting assembly comprises an illumination component having at least one light input surface and at least one light emission surface, a solid-state light source configured to emit at least some light into the at least one light input surface of the illumination component, a polarization manipulation region configured to alter a polarization of light in a different way for light impinging on different locations of the polarization manipulation region, and a polarizer configured to receive at least some light emitted via the at least one light emission surface of the illumination component and further configured to output light having a first polarization and return, to the polarization manipulation region, light having a second polarization.
