Paper Abstract

A specialty solid coupled (SSC) optical taper was introduced into the receiving termination for the rectilinear mobile wireless optical communication. Based on the curvature-shape matching relationship, the profile curve equation for SSC optical taper has been deduced. According to ray-tracing method, the optical coupling efficiency can be analyzed by the comparing the input and output light energy based on Fresnel reflection loss principle. The variation relationships among the taper length, shape factor, large end radius, small end radius, radial displacement, incidence depth, and coupling loss are analyzed. The results show that the theoretical simulation is in good accordance with the experimental data. The errors were also given. The coupling loss was less than 10dB as the radial displacements vary within 1.5 mm in x and y directions, respectively. For this experimental system, the receiving performance of SSC optical taper can satisfy the communication.
