Class Information
Number: 385/17
Name: Optical waveguides > With optical coupler > Switch (i.e., switching from one terminal to another, not modulation) > Matrix switch (i.e., m x n, where m and n are 3 or more)
Description: Subject matter wherein a plurality of switches can selectively couple light on any of M input waveguides to any of N output waveguides where the M input waveguides and the N output waveguides form a rectilinear array.
