The present disclosure discloses an anti-reflection coating and a method of forming the same. According to one embodiment of the present disclosure, the anti-reflection coating includes a first layer positioned on a substrate to be spaced apart from the substrate by a first distance and a second layer positioned on the first layer to be spaced apart from the first layer by a second distance. In this case, the first and second layers are a metamaterial forming a structural double layer and are realized as an anomalous dispersive medium that does not absorb incident light. The structural double layer may realize spatiotemporal dispersion that varies depending on an incidence angle using the nonlocality of the electromagnetic wave reaction of incident light.

Anti-reflection coating and method of forming the same

An optical device including slots and an apparatus employing the optical device are provided. An optical unit device for selectively transmitting electromagnetic waves of a wavelength range, includes a material layer including slots. A gap between the slots has a distance such that the optical unit device has a Q-factor of about 5 or more.

Optical device including slot and apparatus employing the optical device

A new high-performance, compact microgyroscope is implemented using a microlaser such as a microsphere laser or a microdisc laser that can be easily reduced in size. The microgyroscope includes a pumping unit for inputting pumping light for optical pumping, at least one microsphere or microdisc for oscillating a laser beam by performing optical pumping using light received from the pumping unit, an output coupler for receiving the oscillated laser beam from the microsphere or microdisc, and a photodetector for calculating a beat frequency due to interference between beams output from the output coupler to measure rotation. The pumping unit and the output coupler are constructed using a tapered optical fiber.
