The emerging field of silicon photonics targets monolithic integration of optical components in the CMOS process, potentially enabling high bandwidth, high density interconnects with dramatically reduced cost and power dissipation. A broadband photonic switch is a key component of reconfigurable networks which retain data in the optical domain, thus bypassing the latency, bandwidth and power overheads...
A polarization diversity circuit in silicon waveguide was developed. The polarization dependent loss is 0.5 dB. The insertion loss from the polarization diversity components is 3 dB. The extinction ratio of the ring circuit is 20 dB.
By leveraging on the wealth of Si-CMOS technology know-how and the largely available infrastructures, the fundamental photonic device building blocks and circuit integration platform, essential for the realization of the electronic-photonic integrated circuit (EPIC), have been successfully developed. This presentation gives an overview on the current status of this critical technology and provides...
Silicon nanophotonics provides computer architects with the ability to solve pin bandwidth and cross-chip communication problems. Furthermore, ring resonators can be used to create simple optical circuits to implement low-latency global arbitration.
In this paper, we report a direct comparison between coupled resonator optical waveguides (CROWs) and photonic crystal waveguides (PhCWs), which have both been exploited as tunable delay lines. The two structures were fabricated on the same silicon-on-insulator (SOI) technological platform, with the same fabrication facilities and evaluated under the same signal bit-rate conditions. We compare the...
Recent developments have shown the possibility of leveraging silicon nanophotonic technologies for chip-scale interconnection fabrics that deliver high bandwidth and power efficient communications both on- and off-chip. Since optical devices are fundamentally different from conventional electronic interconnect technologies, new design methodologies and tools are required to exploit the potential performance...
To provide flexibility in implementing polySi devices in Si optoelectronic integrated circuits, polySi wire waveguides were fabricated with various low thermal budget solid-phase crystallization (SPC) approaches, i.e., spike rapid thermal annealing (RTA) at 1050??C for < 1 s, low-temperature annealing (LTA) at 600??C for 15 h, or a combination of both with different sequences. The approach of first...
Silicon photonic wire waveguides, featuring a very strong optical confinement and compatibility with silicon electronics, provide a compact photonic platform on which various passive, dynamic and active devices can be constructed.
The silicon nanophotonic devices have a strong potential to increase tremendously the 10 capacity for inter- and intra-chip connectivity up to a Terabit/sec data rates as well as lower significantly the overall IO power consumption below 1 mW per Gigabit/sec. A concept of a 3DI integrated microprocessor chip with lower layer having hundreds of processing cores, an intermediate memory layer (or multiple...
Silicon photonics is no more an emerging field of research and technology but a present reality with commercial products available on the market, where low dimensional silicon (nanosilicon or nano-Si) can play a fundamental role. After a review of the field, the optical properties of silicon reduced to nanometric dimensions are introduced. The use of nano-Si, in the form of Si nanocrystals, in the...
Temperature-dependent wavelength shift of a silicon waveguide is theoretically and experimentally studied and a temperature-insensitive silicon ring resonator is fabricated using a polymer overlay.
