We analyzed and fabricated a novel coupler which possesses wavelength flattened response and splitting ratio tuning capability. The fabricated coupler showed a flattened response to wavelength over 50 nm bandwidth and the coupling power to the cross port can be tuned from 10% to 70%.
• Silicon Photonic Integrated Circuits are here with good performance (and lower cost in volume). - High Q: narrower linewidth DFBs, tunable DBRs, mode locked lasers • Integration is essential for size, weight, power and cost reduction and improved yield and reliability • Photonics can allow lower power and higher capacity for - Data Centers - Supercomputers - Sensors - Silicon Interposers
