Silicon Integrated Waveguide Devices for Filtering and Wavelength Demultiplexing
Optical Fiber Communication Conference, 2010Following different approaches, we have realized a number of different silicon integrated demultiplexers for WDM-based on-chip optical interconnects. We compare these devices based on their size, transmission loss, pass-band shape and tolerance against process variations.

a b s t r a c t Three-dimensional numerical modeling of a controlled plasmonic filtering device based on Au nanorings in an SiO2 host has been investigated. It is shown that a certain plasmon waveguide based on an ordered array of Au nanorings which utilized as a waveguide ring resonator (WRR) can be used to control the propagated optical energy and ...

In this study, we investigated quantum dot intermixing (QDI) for InAs/InGaAlAs highly stacked QDs on an InP(311)B substrate with low-temperature annealing at 650 °C in order to realize integrated photonic devices with QDs and passive waveguides. In particular, we adopted the method of introducing point defects by ICP-RIE to realize a blue shift of the ...

For the first time, an optimized optical add-drop filter (OADF) for dense wavelength-division-multiplexing systems is demonstrated using the Texas Instruments microelectro-mechanical-system Digital Micromirror Device (DMDtrade). This OADF features a polarization-insensitive fault-tolerant broadband operation, low loss, and the ability to selectively ...

Optical multi/demultiplexer device, optical wavelength selective filter and method of making filter
2004Optical multi/demultiplexer (4) device comprising a substrate, a plurality of wave guides (45, 46, 47, 48) on a surface of said substrate, a plurality of selective wavelength filters (452, 462, 472, 482). Each of said plurality of filter is able to transmit a first predetermined band of wavelengths (PB') and to reflect a second predetermined band (SB').
