Efficient Multimode Optical Fiber-to-Waveguide Coupling for Passive Alignment Applications
نویسندگان
چکیده
An efficient optical fiber-to-waveguide coupling technique is described, using a novel transcision cut, alignment ways, and D-shaped fibers. Fiber-to-waveguide coupling efficiencies as high as 96% have been achieved with multimode graded-index fibers and ridge polymer optical waveguides. Advantages of using this new coupling technique include ease of fiber-to-waveguide alignment interior to the substrate edge, passive coupling, and high coupling efficiency.

Using of Broadened Asymmetric Waveguide Structure for 980nm Diode Laser
Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...
