Efficient Fiber-to-Waveguide Edge Coupling Using an Optical Fiber Axicon Lens Fabricated by Focused Ion Beam
Efficient edge coupling into a silicon waveguide is demonstrated using an optical fiber axicon lens operating at 1550 nm. The axicon was fabricated on the cleaved endfacet of an SMF-28e optical fiber using a focused ion beam milling process. The lens converts the guided mode of the optical fiber (mo...
