Short and robust silicon mode (de)multiplexers using shortcuts to adiabaticity
2015
Optics Express
Preserved Fulltext
Compact silicon mode (de)multiplexers based on asymmetrical directional couplers are designed using shortcuts to adiabaticity. The coupling coefficient and propagation constants mismatch are engineered to optimize the device robustness. Simulations show that the devices are broadband and have large fabrication tolerance.
