Abstract
The length of NxN multimode interference-based devices scales as the square of the MMI region width, and as a result, the use of these structures for large-N applications can require large chip areas. We discuss the NxN applications of a recently proposed MMI structure which has smaller device dimensions than conventional multimode interference structures. Numerical simulations of such structures and design rules are presented.
