Research Topics


A loss-less, polarization insensitive optical power splitter is proposed here based on the integration of multimode interference couplers and semiconductor optical amplifiers (SOA). The proposed effort addresses the key issue of integration of passive and active devices, the optimum architecture for maintaining signal to noise ratio, manufacturability and the design's ability to scale to large splitting array. The multimode interference coupler, the semiconductor optical amplifiers, and fan-out waveguides will be individually modeled and optimized and incorporated in a 1 x 16 loss-less splitter design. The splitter will be fabricated and characterized for its RF performance. BENEFITS: The main benefit will be for the phased array antenna phase shifters and optical switching networking.
