The demand for higher bandwidth and higher speed driven by semiconductor technology development draws a great deal of research efforts devoted to the development of high speed data communication. Challenges on electrical copper interconnects at high frequency make optical interconnect technologies become a promising alternative to conventional electrical interconnects at different levels. This doctoral dissertation describes polymer based nano- and micro-photonic devices for three-dimensional optical interconnects. Two areas are focused, (1) polymer based two-dimensional (2D) and three-dimensional (3D) photonic crystal fabrication and simulation for laser beam steering applications, (2) polymer based optical waveguide array and shared bus waveguide with embedded 45° micro-mirrors for board level optical interconnects. A three-dimensional (3D) face-centered cubic (FCC) type polymer based photonic crystal using the polymer material SU-8 was simulated and successfully fabricated using a polygonal prism based holographic fabrication method. The theoretical study of polymer based photonic crystals was carried out for laser beam steering, which is based on the superprism effect. Horizontally stacked two-dimensional (2D) photonic crystal was fabricated by a double exposure holographic interference method. The k-vector superprism effect, the principle for beam steering, was studied in detail through EFC (Equi-frequency Contour) analysis. A polymer based optical waveguide array with embedded 45° micro-mirrors for board level optical interconnects was prepared using a Ni metal hard mold by a UV imprint technique. A nickel based metal mold with 45º tilted surfaces on both ends of the channel waveguide was prepared through the electroplating process. To obtain a precise 45º tilted angle, a 50µm thick SU-8 layer was exposed under de-ionized water. High speed optical testing (10Gb/s) was carried out on the polymeric optical waveguide array with embedded 45º micro-mirrors on flexible substrate for out-of-plane optical interconnects. A polymer based 3-to-3 shared optical bus waveguide with opposite 45º micro-mirrors was designed and fabricated using the metallic hard mold method. The Ni metal hard mold was successfully prepared using the Ni electroplating method. This metallic hard mold provides a convenient way to fabricate the polymeric optical bus waveguide devices through the imprint technique. / text

Parallel optical interconnects (POI) have attracted a great deal of attention in the past two decades as the system bandwidth continues to increase. Optical interconnects are known to have more advantages than their electrical counterparts in many aspects such as crosstalk, bandwidth distance product, power consumption, and RC time delay. The parallelization of several optical links is also an effective method to increase the aggregate data rate while keeping the component count manageable and to reduce the unit cost of optics, electronics, and packaging at lower line rate. / Parallel optical transceiver modules running at several gigabits per second are commercially available nowadays. Parallel optical receivers are one of the key components of parallel interconnected systems. In this work, we describe how a low-power parallel CMOS preamplifier IC and a deskew IC have been designed and fabricated through the IBM 0.13mum CMOS technology. The performances of three different transimpedance amplifier (TIA) topologies are compared experimentally. The best of the three TIAs shows a differential gain of 56.2dBO, 2.6GHz bandwidth, and less than -16dBm sensitivity with a bit-error-rate (BER) less than 10-12. The TIA consumes 2.5mW of power from a 1.2V supply while the channel power is 22mW with a 400mV pp differential output swing. / A novel method of accurately measuring the crosstalk power penalty with an on-chip PRBS generator is proposed and its implementation is described. The use of an on-chip PRBS generator to drive the dummy channels eliminates the data pattern dependence between the aggressors and the victim. The inevitable channel skew associated with parallel channels can be removed by a phase-locked loop (PLL) based deskew method. We investigated the skew compensation range of this method theoretically and our experimental results confirm our conclusion. / Various practical design and test techniques such as photodiode modeling, AC coupling, low-pass filtering and continuous skew generation, and their implementations, are discussed and implemented in this thesis.
