Mookherjea and the Micro/Nano-Photonics group () study chip-scale linear, non-linear and quantum photonic devices. Coupled microring devices have been used for highly efficient four-wave mixing and room-temperature heralded single photon generation from a silicon chip, in collaboration with IBM and NIST. Research has studied theoretically and experimentally the effects of disorder in high index contrast waveguide structures, and demonstrated light localization in periodically-patterned silicon waveguides. Devices fabricated by the group have been used by collaborators to generate infrared light by nonlinear wavelength conversion from compact fiber-optical seed sources, and in microfluidic mixers / sensors. In parallel to functional device development, the group’s research also focuses on the fundamentals of modeling, measuring and improving the behavior of inter-connected high-index contrast silicon photonic devices, e.g., loss and disorder estimation from statistical analysis of light propagation, spatially- and spectrally-multiplexed infrared diagnostic method in silicon multi-ring resonator circuits, and nano-oxidation of silicon rings and interferometers.
