Broadband mode converters in three-waveguide couplers based on quantumlike adiabatic transfer

Résumé

We propose a method for robust mode conversion between the two outer waveguides in a three-waveguide coupler based on analogies with quantum population transfer. Depending on the presence or absence of detuning between the propagation constants of the intermediate waveguide, the mode conversion can be analogous to the adiabatic-elimination or stimulated Raman adiabatic passage techniques. Both configurations give broadband and robust mode converters.
