Numerical analysis of misalignment effects in few-mode multi-core fiber systems
11:15-11:30
2017-10-03 11:15 2017-10-03 11:30 America/Denver Numerical analysis of misalignment effects in few-mode multi-core fiber systems Few-mode multi-core fiber systems tend to be more prone to core misalignments at splice points. By using the true vector modes of few-mode waveguides we analyze how waveguide properties affect the shape of coupling and mode-dependent loss distributions due to alignment errors between waveguides.

Fabrication of a Gradient-Index Optical Fiber Lens by Focused Ion Beam
11:30-11:45
2017-10-03 11:30 2017-10-03 11:45 America/Denver Fabrication of a Gradient-Index Optical Fiber Lens by Focused Ion Beam We fabricate a gradient-index lens on the end facet of an optical fiber by focused ion beam. At 1550 nm, the lens generates a 2.2 µm spot at a working distance of 4.2 µm. This lens can be used for efficient edge-coupling into optical chip. Hilton Santa Fe Historic Plaza Salon VI
