We present a new monolithic silicon photonics technology suited for integration with standard bulk CMOS processes , which reduces costs and improves opto-electrical coupling compared to previous approaches. Our technology supports dense wavelength-division multiplexing with dozens of wavelengths per waveguide. Simulation and experimental results reveal an(More)
We demonstrate a monolithic photonic integration platform that leverages the existing state-of-the-art CMOS foundry infrastructure. In our approach, proven XeF2 post-processing technology and compliance with electronic foundry process flows eliminate the need for specialized substrates or wafer bonding. This approach enables intimate integration of large(More)
A new general class of optical interferometers is proposed, and the physical principle of their operation is explained. They split the spectrum entering one input port among the interferometer arms in an arbitrarily chosen wavelength- and/or time-dependent manner but guarantee broadband constructive interference into a single output port by symmetry. The(More)

This paper presents photonic devices with 3 dB/cm waveguide loss fabricated in an existing commercial electronic 45 nm SOI-CMOS foundry process. By utilizing existing front-end fabrication processes the photonic devices are monolithically integrated with electronics in the same physical device layer as transistors achieving 4 ps logic stage delay, without(More)
The goal of the research program that we describe is to break the emerging performance wall in microprocessor development arising from limited band-width and density of on-chip interconnects and chip-to-chip (processor-to-memory) electrical interfaces. Complementary metal-oxide semiconductor compatible photonic devices provide an infrastructure for(More)
Integrated photonic interconnect technology presents a disruptive alternative to electrical I/O for many VLSI applications. Superior bandwidth-density and energy efficient operation can be realized through dense wavelength-division multi-plexing (DWDM) and lower transmission losses. There are two main paths towards an integrated platform.(More)
Low-loss, compact, broadband silicon-waveguide crossing arrays and active structures are proposed based on periodicity-matched multimode focusing. Simulations show loss of 0.045dB/crossing and >200nm bandwidth in a typical example. Correspondence to low-loss, structure-matched Bloch-waves is demonstrated. Strong-confinement (SC) waveguides based on high(More)
M2 protein of influenza A viruses is a tetrameric transmembrane proton channel, which has essential functions both early and late in the virus infectious cycle. Previous studies of proton transport by M2 have been limited to measurements outside the context of the virus particle. We have developed an in vitro fluorescence-based assay to monitor internal(More)
