This `sandwich' technique composes layers of planar integration with the major goal of minimizing (1) the number of interconnections between adjacent layers with slopes (2) the number of crossing waveguides within single layers and between adjacent layers and of optimizing (3) the number of layers. This is a multi-level optimization problem whose first step can be solved by utilizing the symmetry of the 3D architectures. The presented work explains concepts and prepares their geometry for the ongoing physical analysis. The presented architectures are restricted to passive switches, capable to provide e.g. all-optical logic circuits. Hints for an extension towards active switches are also briefly presented.","PeriodicalId":111143,"journal":{"name":"International Topical Meeting on Optics in Computing","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127702905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is done through the development of the technology necessary for the realization of such interconnections, and the definition of a systems architecture in which these interconnections play a meaningful role. Field-programmable gate arrays (FPGA) have been identified as a class of general-purpose very large scale integration components that could benefit from the massive introduction of state-of-the-art optical inter-chip interconnections at the logic level. In this paper, we present the realization of a small-scale optoelectronic FPGA with 8 X 8 logic cells, containing two optical sources and two receivers per FPGA cell yielding a total of 256 links per chip. These FPGA chips designed to operate with information rates of 80 Mbit/s/link will be used in a three- chip demonstrator system as a test bed for the concepts above. We first identify the reason why we think optical interconnects can provide added value in FPGAs. The next sections briefly discuss the general architecture of our demonstrator system and the realization of the optoelectronic FPGA. We then present first measurement results followed by ongoing work and conclusions.","PeriodicalId":111143,"journal":{"name":"International Topical Meeting on Optics in Computing","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133986619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transpar-TR moves data through the network in the form of 3D packets (2D spatial and 1D time). By utilizing many spatial parallel channels, Transpar-TR can achieve high throughput, low latency communication between nodes, even with each channel operating at moderate data rates. The 2D array of optical channels is created by an array of smart pixels, each with an optical input and optical output. Each smart pixel consists of two sections, an optical network interface and ALU-based processor with local memory. The optical network interface is responsible for transmitting and receiving optical data packets using a slotted token ring network protocol. The smart pixel array operates as a single-instruction multiple-data processor when processing data. The Transpar-TR network, consisting of networked smart pixel arrays, can perform pipelined parallel processing very efficiently on 2D data structures such as images and video. This paper discusses the Transpar-TR implementation in which each node is the printed circuit board integration of a VCSEL-MSM chip, a transimpedance receiver array chip and an FPGA chip.","PeriodicalId":111143,"journal":{"name":"International Topical Meeting on Optics in Computing","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133417910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
