Intrachip optical interconnects (OIs) have the potential to outperform electrical wires and to ultimately solve the communication bottleneck in high-performance integrated circuits. Performance… (More)
We characterize experimentally the anisotropy of two-photon absorption and the Kerr nonlinearity in silicon over a broad spectral region.
We theoretically and experimentally demonstrate a compact silicon photonic crystal microcavity sensor capable of detecting in vivo a single particle of size comparable to a virus.
Electrical tuning of high refractive index-contrast photonic bandgap (PBG) structures is required for a majority of PBG applications, particularly for integrated optics. When the host material is a… (More)
We propose a new geometry for an optical sensor that is based on porous silicon structures. The sensitivity of the sensor is enhanced compared to the conventional surface plasmon resonance based… (More)
Integration of electrical and fluidic systems for the design and fabrication of a system-on-chip (SOC) capable of sensing various liquid phase solvents is reported. A monolithic integration strategy… (More)
We report on multiple resonant cavities coupled to a single photonic crystal waveguide operating as a multi-channel sensor. This device is characterized by as many dips in its transmission spectrum… (More)
We theoretically and experimentally present a Si-based photonic crystal sensor for single particle detection. With a sensing area of ~40 mum2, the device is capable of detecting a sphere of ~50 nm in… (More)
Summary form only given.Commercial ultrafiltration and dialysis membranes have broad pore size distributions and are several orders of magnitude thicker than the molecules they are designed to… (More)
Using a subpicosecond electro-optic sampling technique, we have characterized the photoresponse of current-biased YBa/sub 2/Cu/sub 3/O/sub 7-x/ (YBCO) photodetectors, designed as 5-/spl mu/m-wide and… (More)
