摘要： An optical connector includes a first optical fiber and a second optical fiber. A first planar lens is positioned to operate on light exiting the first optical fiber to create a predetermined change in a wave front of the light. A second planar lens is positioned to accept the light from the first planar lens, the second planar lens focusing the light onto the second optical fiber. The first planar lens and second planar lens each include a regularly spaced array of posts with periodically varying diameters.

In one aspect, an optical isolator includes a Faraday crystal with a first surface and a second surface opposite the first surface, a first one-dimensional sub-wavelength grating disposed on the first surface, and a second one-dimensional sub-wavelength grating disposed on the second surface. The isolator is to receive a first input beam of light on the first grating and output a polarized first output beam of light through the second grating approximately parallel to the first input beam. The isolator is to also receive a second input beam of light on the second grating and output a polarized second output beam of light through the first grating with the second output beam offset from the second input beam.
