Gradient refractive index (GRIN) optics represent a transformative approach in optical design whereby the refractive index varies continuously within a material rather than remaining uniform. This ...

A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

A multimode optical fiber in which the refractive index of the core declines from its highest value at the center of the core to a value at the edge of the core that equals the refractive index of the ...

Researchers reported a novel technology enhancing the high transparency of refractive polymer film via a one-step vapor deposition process. The sulfur-containing polymer (SCP) film produced by ...

A research team develops a transparent silicon without visible light loss by controlling the silicon atomic structure. A POSTECH research team has developed a transparent amorphous silicon that ...
