## Abstract

Super-resolution optical components and left-handed materials thereof are provided. A left-handed material includes a substrate, a plurality of deformed split ring resonators (DSRR), and a plurality of metallic bars, wherein the DSRR and the metallic bars are disposed on the substrate with each DSRR and metal bar alternately arranged.

## Claims

### Claim 1

A waveguide component, comprising:
a light source emitting a light;
a light-coupling device conducted to transmit the light;
a left-handed material conducted to disperse the light processed by the light-coupling device; and
a dispersion waveguide component conducted to receive the light dispersed by the left-handed material;
wherein the left-handed material comprises a substrate, a plurality of deformed split ring resonators disposed on the substrate, and a plurality of metallic bars directly disposed on the substrate;
wherein each of the plurality of deformed split ring resonators and each of the plurality of metallic bars are alternately arranged.

### Claim 2 (depends on 1)

The waveguide component as claimed in claim 1, wherein the light source is a multi-wavelength laser.

### Claim 3 (depends on 1)

The waveguide component as claimed in claim 1, wherein the light-coupling device is a fiber.
