Abstract
The present invention discloses a switching matrix configuration to reduce the optical propagation losses and coupling losses. The switching matrix comprises M horizontal waveguides interested with 2N vertical waveguides, where M and N are positive integers and the optical switching system is configured to receive a multiplexed input optical signal from a horizontal waveguide disposed next to an i-th horizontal waveguide where i is a closest integer to a positive real number M/2.
