名稱A New Approach to the Wavelength Non-Uniformity Problem of Silicon Photonic Microrings
年度2011
類別期刊論文
摘要Light modulators and switches based on silicon photonic microrings can be fabricated with the conventional CMOS technology. For the first time, an optical interconnect integrated on a VLSI electronic die can be realistically envisioned. In spite of this exciting development, there is still one fundamental problem that must be overcome: wavelength non-uniformity, which is a result of miniaturization of the ring and the precision limit of the current fabricating process. Existing electronic or thermo-optical tuning methods are simply not scalable. An approach that combines techniques from both the device and architecture points of view is presented in this paper. It intends to show how the device-level wavelength non-uniformity problem can be tackled at the architecture level. An analytical model is also developed for evaluating the probability of finding a common wavelength among multiple microring resonators. The model can provide useful insights into the design of any microring-based interconnection network.

名稱Crosstalk Analysis for Microring Based Optical Interconnection Networks
年度2012
類別期刊論文
摘要Recently a new approach was proposed to tackle the wavelength non-uniformity problem of the silicon photonic ring technology. By lowering the Q value of the ring, the likelihood of finding a common operating wavelength can be significantly increased. But lowering Q will increase the crosstalk level in such a network. This crosstalk problem can be tackled with a generalized space dilation technique. Since crosstalk is a central issue of this approach, computing the crosstalk level accurately is critical for a microring-based photonic interconnect. Prior work on crosstalk analysis for interconnects based on directional couplers assumed that the extinction ratios are the same for the two switching states. But this is usually not the case for silicon photonic microrings. In this paper, we develop an analytical model for analyzing the crosstalk level in a microring-based optical interconnection network. The analytical approach presented in the paper can be used for studying the crosstalk problem in optical networks based on other optical switching technologies.

名稱Exploiting Two-Wavelength Switching Capability of Silicon Photonic Microrings
年度2013
類別期刊論文
摘要Silicon photonic microrings have the capability of handling two wavelengths simultaneously and this capability does not exist in other types of photonic switching technologies, such as directional couplers or MEMS. Exploiting this two-wavelength switching capability has not been done before. In this paper, we use this capability to construct a new type of microring-based non-blocking optical interconnects. For a 4 4 network, the new architecture only needs four rings. In contrast, the conventional crossbar-based architecture requires 16 rings. For medium size switches, such as 8 ports or 16 ports, the new architecture also requires significantly fewer rings than conventional crossbar switches of the same sizes.

名稱Repackable multi-Log_2 N networks
年度2016
類別期刊論文
摘要Multi-Log_2 N networks have a wide range of applications in telecommunications. In this paper, we present a new type of nonblocking multi-Log_2 N networks, called repackable nonblocking, wherein rearrangement activities are required only during the departures, but not upon arrivals. Furthermore, the frequency of rearrangement activities is so low that under many circumstances, they perform like strictly nonblocking networks but with a much lower hardware complexity.
