This video demonstrates several new products based on the nanostructures fabricated directly on the optical fiber facet. For this demonstration, we have a fiber-coupled laser that is connected to a fiber splitter. This way, we have the light coming out of two fibers. The first output I connect to a regular single-mode fiber. The beam coming out of the fiber has Gaussian shape and diverges with 0.13 radian numerical aperture. The next output I connect to the fiber with a nanostructure fabricated on its facet. The beam coming out of the nanostructured fiber is an optical vortex that carries orbital angular momentum. It is created by a spiral phase plate on a fiber's edge. The beam has a donut shape. Optical vortices are used instead microscopy, telecommunications, and optical trapping. Another structure that can be fabricated on a fiber is a columnator. Fiber-colometer controls the divergence angle of the output beam, for example, to make the beam narrower. Fiber-colometers are used to match fiber output with a numerical aperture of the optical system and to simplify coupling into fibers. By combining the optical performance of the fiber-colometer and vortex phase plate, we can also control the divergence of the vortex beam. This beam also carries orbital angular momentum, but the divergence angle is much narrower. Our designs can operate from blue light to near infrared. To demonstrate the next structure, I will use a green laser diode. The nanostructure on this fiber is a flat-top beam shaper. While the beam from a regular fiber has a Gaussian shape, the beam from this fiber has uniform intensity in the center. The beam divergence is also much wider. Beam shapers are typically used for illumination applications, including next-generation displays. Fiber optics makes optical setups easy to use, compact, and alignment-free. Using fibers with nanostructures for light manipulation directly on the fiber edge expands the capability of the beam.
