Abstract:
An optical apparatus includes an optical fiber formed of a core surrounded by cladding, in which the optical fiber includes an end portion. In addition, an optical layer composed of a material having a relatively high refractive index is positioned on the end portion, in which the optical layer includes a non-periodic sub-wavelength grating positioned in optical communication with the core.
