Abstract :
Bent multimode interference-based variable power splitters are experimentally demonstrated in GaAs-AlGaAs using the principles of general imaging. Simulations are used to investigate sensitivities to device geometry. Results indicate that the device´s splitting ratio performance is largely fabrication tolerant.
