Polarization crosstalk occurs when light intended for one polarization axis leaks into another, causing interference, increased Bit Error Rate (BER), and a reduction in the overall extinction ratio of the system. In a Time-of-Flight (TOF) application, crosstalk can be from an electrical connection but also from optical coupling. The most important issue in the design of WDM lightwave systems is the interchannel crosstalk. In order to mitigate the measurement errors caused by the crosstalk in the output of the optical fiber array in the new solar radiation measurement method, this paper proposes a method that utilizes a non-spherical lens to eliminate the crosstalk and achieves effective crosstalk elimination through.
