摘要：
A cascade of two directional couplers with a relative phase shift between them, serves as an optical power divider, Simple analytic universal design rules for selecting the appropriate net coupling strength in each device, and for the phase shift, yield maximally flat response in terms of deviations in wavelength, polarization, or uniform fabrication errors, and are applicable to any power division ratio.
