Abstract

Abstract

Dense photonic integration requires miniaturization of materials, devices and subsystems, including passive components (e.g., engineered composite metamaterials, filters, etc.), active components (e.g., modulators and nonlinear wave mixers) and integrated circuits (Fourier transform spectrometer, programmable phase modulator of free space modes, etc.).

Abstract

Abstract

The inherent Ohmic Loss of plamsonic has hampered the commercialization of a novel classes of electro-optic devices. We will discuss recent progress in realizing high Q(>5000) and low Q(<100) plasmonic resonators to overcome this limitation, thus enabling low-loss switches and high-speed modulators beyond state-of-the-art.

Abstract

Abstract

I will describe our demonstration of miniature visible and telecom silicon nitride pure phase modulators based on micro-resonators that are robust to fabrication variations. These devices offer a one-order-of-magnitude reduction in device footprint and power consumption compared to silicon nitride waveguide phase shifters.

Abstract

Abstract

Fast optical limiters are needed to protect sensors from intense short laser pulses. An optical limiter design based on a conducting-oxide grating with a large nonlinear refractive index at the plasma frequency is proposed and investigated.

WD4.5 - SWITCHABLE INDUCED-TRANSMISSION FILTER

Abstract

Abstract

We extended the concept of an induced-transmission filter (ITF) to enable dynamic filtering by incorporating a thin film of vanadium dioxide (VO2), a phase-transition material. By varying the state of the VO2, the filter can be switched between narrow- and broadband transparency.

Abstract

Abstract

Redox reactions serve as a transduction modality for biological to electrical communication and redox-cycling from interaction of a pair of mediators with the analyte can amplify signals. We further amplify the signal responses of a standard redox capacitor by nanoconfinement of the electrochemical signal measurements.

WF1.4 - INVESTIGATION OF NEUROPEPTIDE Y DETECTION BY A SILICON-NITRIDE MICRORING RESONATOR

Abstract

Abstract

We fabricate and functionalize silicon-nitride microring for detecting attachment of Neuropeptide Y (NPY) molecules, commonly associated with human stress. For 4 µg/ml NPY concentration in aqueous solution we experimentally observe ~0.4 nm resonance shift.

Abstract

Abstract

Continuous ultra-weak photon emission without external stimuli or luminphores have been observed in living systems. The intensity of “biophotons” released from this process reflect the physiological state and could serve as an additional mechanism of cellular communication to compliment the established chemical and electrical signaling.
