Integrated nanoscale photonic devices have wide applications ranging from optical interconnects and optical computing to optical communications. Wavelength demultiplexer is an essential on-chip optical component which can separate the incident wavelength into different channels; however, the experimental progress is very limited. Here, using a multi-component nano-cavity design, we realize an u...

Novel latching microfluidic valve structures are developed, characterized, and controlled independently using an on-chip pneumatic demultiplexer. These structures are based on pneumatic monolithic membrane valves and depend upon their normally-closed nature. Latching valves consisting of both three- and four-valve circuits are demonstrated. Vacuum or pressure pulses as short as 120 ms are adequ...

This paper presents two highly integrated receiver circuits fabricated in InP heterojunction bipolar transistor (HBT) technology operating at up to 2.5 and 7.5 Gb/s, respectively. The first IC is a generic digital receiver circuit with CMOS-compatible outputs. It integrates monolithically an automatic-gain-control amplifier, a digital clock and data recovery circuit, and a 1 : 8 demultiplexer, ...

Wavelength Division Multiplexing (WDM) is the key technique for high data rates communication systems. WDM systems offer many advantages for optical communications with several unique features and requirements in terms of their implementation. This is because the design characteristics and realization of WDM components are crucial and depend particularly on the type of materials used for fabric...

We demonstrate a self-organizing photorefractive circuit that demultiplexes a beam that has two signals imposed on separate optical carrier frequencies into two beams, each containing one of the signals on its carrier. Unlike conventional demultiplexing techniques, this method requires little a priori knowledge about the carrier frequencies. The signal channels must be spatially uncorrelated, a...

Phononic metamaterials enabled the realization of many acoustic components analogous to their electronic counterparts, such as transistors, logic gates, and calculators. A key component among these is demultiplexer, a device that receives multiple signals sorts them based on frequencies into separate channels. Previous experimental realizations elastic multiplexers have employed plates with pil...

The paper presents a novel N-channel chained symmetric-Mach-Zehnder-interferometers demultiplexer (CSMZI) for high-speed OTDM networks. The proposed scheme offers parallel demultiplexing capability with reduced complexity. Simulation results show that low bit error rate performance is achieved with low power penalty.

We report the realization of two-dimensional optical wavelength demultiplexers and multiports for surface plasmons polaritons (SPPs) based on plasmonic crystals, i.e., photonic crystals for SPPs. These SPP elements are built up of lithographically fabricated gold nanostructures on gold thin films. We show by direct imaging of laterally confined SPP beams in the visible spectral range by leakage...
