✦ Synopsis

For the potential realization of optical interconnect scheme based on modal diversity, we propose and analyze efficient mode add drop multiplexers (MADM). Each of the two types of MADM proposed here enables a simultaneous two channels (modes) add/drop to/from a multimode bus. The simultaneous operation is of importance in reducing the device footprint within the expected ultra-dense interconnects schemes. We developed analytical design rules for the adiabatic devices and verified by simulation that an implementation based on Silicon over Insulator waveguides, is exhibiting low loss and low channels crosstalk (below À22 dB).
