Although humans are profoundly social, we know very little about the underlying neural systems that are associated with live interactive social behaviors because most imaging studies acquire data from only one participant at a time. Functional near infrared spectroscopy, fNIRS, is employed to simultaneously image two individuals during live face-to-face interactions. We test the hypothesis that emotional contagion via facial expressions is related to neural mechanisms also engaged in automatic dyadic facial mimicry. Behavioral findings including facial classifications and emotional ratings are consistent with the hypothesis. Further the neural results suggest that known social systems of the human brain located in the right temporal parietal junction include a complex of sub components and mechanisms for encoding facial mimicry and associated emotional meaning. A model of embodied emotion is supported.

Here, a high-speed optical modulator with 40 GHz bandwidth, robust athermal operation, complementary metal-oxide-semiconductor (CMOS) compatibility, and using the magical critical coupling loss, is presented for photonic integrated systems and computing applications. The energy per bit of operation of 1fJ/bit is observed in the proposed device.

We designed and characterized a 4x4 wavelength-selective switch that is spectrally partitioned in the O-band for energy efficient data center applications. Each switch block has 3 different sized micro-ring resonator pairs for a flat response and minimal thermal tuning.

Although discrete lasers grown on silicon have been demonstrated, light coupling into on-chip passive waveguides remains to be properly studied. We investigate theoretically the optical coupling between 2.3 μm GaSb-based diode lasers (DLs) epitaxially grown on a Silicon photonic chip and the passive waveguides.

We experimentally demonstrate compensation of intra-modal crosstalk using a standard coherent receiver architecture. We examine performance and equalizer complexity for various fiber lengths and OAM mode orders. We determine the shortest equalizer length achieving BER below the 7% FEC threshold at 1550 nm.

We propose an evolutionary algorithm-based multi-objective optimization method of all-dielectric metasurfaces for sensing using Rigorous-Coupled-Wave-Analysis (RCWA). To demonstrate, we optimized a Si nano-dimer. Simulation results show a Fano resonance with a quality factor of 53570 at 1500nm wavelength and sensitivity of 292 nm/RIU.
