Crosstalk in Free Space Optical Interconnects that Use Micro-Lenses Arrays: Practical Consideration
The effect of positive spherical aberration of micro-lens on the optical crosstalk in free space optical interconnects is considered. Using the derived field distribution at the detector array, the optical crosstalk level is evaluated and numerical results are provided. It is found that practical lenses with positive spherical aberration increases the crosstalk and degrade the system performance.
