Abstract
In this paper, solid immersion lenses (SILs) in silicon-based planar waveguides are designed and fabricated. The lenses are designed by the ray-tracing method to optimize the lens profiles. Experimental results show that a minimum spot size of 0.77 μm can be obtained as the calculation prediction. Hence, the SILs combined with other optical components in planar waveguides can alleviate the alignment, tilt, and packaging problems in free-space optical systems.
