Table 1 Configurations for LP01 transformation and results. (zo, a, zt, t) combinations producing simultaneous δp - δs minimization at z > 67.5 μm and δs < 0.01. The corresponding δs and δp values can be found in the second column. The ratio between the final and initial mode power and the overlap integral η are given in the third column
