Integrated photonic power divider with arbitrary power ratios [PDF]
Optics Letters, 2017 Integrated optical power splitters are one of the fundamental building blocks in photonic integrated circuits. Conventional multimode interferometer-based power splitters are widely used as they have reasonable footprints and are easy to fabricate. However, it is challenging to realize arbitrary split ratios, especially for multi-outputs.

Broadband Equal Power Divider [PDF]
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2017 Abstract This paper presents the design of broadband two way equal power divider in microstrip medium with defected ground structure suitable for broadband communication systems. Quarter wave broadside coupled lines are used in the place of conventional transformers widely used in the popular Wilkinson power dividers.

Constructing Sequences of Divided Powers [PDF]
Proceedings of the American Mathematical Society, 1972 In my Sequences of divided powers in irreducible, cocommutative Hopf algebras, I demonstrated the existence of extensions of sequences of divided powers over arbitrary fields, if certain coheight conditions are met. Here, I show that if the characteristic of the field does not divide n, every sequence of divided powers of length n 1, in a cocommutative
