AI Technical Summary
In optical communication through spatial coupling, determining whether the light diameter of collimated light is within a defined range in a double mode is challenging due to the varying light intensity distribution profiles of the fundamental and first-order modes, making it difficult to guarantee communication quality.
A method is developed to determine the light diameter of collimated light within a defined range by analyzing the ratio of the fundamental mode to the first-order mode and defining an annular region between two circles, where the 1/e^2 line of the light intensity distribution falls, to ensure accurate alignment and communication quality.
This method allows for reliable determination of the light diameter in double-mode optical communication systems, enabling effective rejection of nonconforming items and ensuring consistent communication performance.
