“…This subject has been extensively studied for the coupling of coherent Gaussian beams [1][2][3][4][5] as well as of incoherent radiation. [6][7][8][9][10] For the case of coherent plane wave coupling 11,12 the important interplay between angular and lateral misalignment does not seem to have been sufficiently studied.…”

“…We observe that the two electric fields are almost the same. The coupling coefficient [23, 24] of the two waveguides (cylindrical and planar) can be calculated from the following equation Couplingthinmathspacethinmathspacecoefficient= |EcylEpladS1.2em1.2em|2negativethinmathspacenegativethinmathspace1.2em1.2em|Ecyl|2normaldS|Epla1.2em1.2em|2dSwhere E cyl is the field distribution of the cylindrical waveguide, E pla is the field distribution of the planar waveguide and d S is a single surface element. The value of the integral (12), for the two modes in our example, is calculated to be 0.999997.…”
