For beginners - ODIS - global domination
ODIS - Company Description and Overview
Odis is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Thyristor-HFET logic based on optical signal transfer. The abstract given for this project is as follows: The digital signal processor is currently dominated exclusively by CMOS technology. This is largely due to the fact that it is the only low power (VLSI density) technology available. However, CMOS is near the end of its scaling potential and it has a severe liability for space applications due to a weakness to radiation. Recent progress in integrated optoelectronics has indicated dramatic performance improvements in clock and data recovery and in the mux/demux operations are possible. This may also apply to digital logic functions. For example the basic flip flop function could be implemented with EO devices activated by optical signals and producing optical outputs. Such approaches could reduce the number of devices and the power while simultaneously increasing the speed. ODIS proposes a new technology base to enable this digital flip flop implementation. The latching function is provided by an EO thyristor which produces laser light in the on state. Optically activated transistors control the switching functions. This approach is compatible with optical signal transport, with on chip optical clock generation and timing control and with optical I/O. In this work, ODIS will develop J-K flip flops and their related synchronous circuits based on a new GaAs optoelectronic integration platform.BENEFIT:The digital processor market is several billion dollars with steady growth potential based upon an expending PC industry. As CMOS is constrained by power and speed , the opportunity for GaAs based circuits is significant. The wireless industry is already using all of the GaAs amplifiers that are produced. One can therefore expect a market opportunity for GaAs based digital products with large up-side potential. Digital products can now be added to a growing number of markets addressed by integrated optoelectronics including AD converters, imager products, parallel optical data links, optical interface circuits, phased array receivers and other markets currently dominated by Si.
Odis is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Optoelectronic directional couplers for optical switching fabrics. The abstract given for this project is as follows: Optical switching fabrics (optical cross-connects) require arrays of highly interconnected optical switching devices. Such fabrics require a high density of optical and electronic interconnect. The optical switching devices are also required to switch configurations in sub-ns time intervals to enable reconfiguration times between packets that introduce little if any latency. Currently such fabrics do not exist commercially (8x8 demonstrated) and all routing is done with circuit switched architectures. Possible candidates include MEMS mirror arrays, electro-optic switches, interferometric switches, digital optical switches, liquid crystal switches, bubble switches, acoustooptic switches and semiconductor amplifier switches. The issues are insertion loss, crosstalk, extinction ratio, polarization dependence and scalability. The only approach with high speed potential is the electro- optic switch. The only electro-optic switch with small size and scalability is the semiconductor based directional coupler. The only semiconductor directional coupler that can be scaled to lengths <500um and that may be integrated with other optical and electronic circuits is fabricated in POET a new platform technology for OE integrated circuits. In this SBIR, ODIS will develop the directional coupler as the key switching device within the fabric and demonstrate the potential for sub-ns switching, low insertion loss, high density and connectivity to a router processor.BENEFIT:marketed by the major server suppliers and telecommunication networking companies such as Ciena, Juniper, Cisco, Netgear etc. The optoelectronic chip developed here will outperform and other challenging technology by an order of magnitude. Therefore market penetration is assured. This technology platform will also address the other issues in optical routers such as wavelength conversion, optical DRAM, high speed logic within the router processor etc. One can therefore expect a proliferation of communications products based on optoelectronic designs.
Odis is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Photonic control technology for Phased Arrays. The abstract given for this project is as follows: Phased arrays radars can expect considerable improvements with RF photonics. Current TR modules use numerous MMIC chips, ferrite circulators and phase shifters and quasi-optical true-time-delay (TTD). Transmission power distribution and synchronization across multiple RF interfaces can be improved. Large scale integration could address the problem of interconnecting boards with GHZ RF outputs but currently is not possible. Such integration with optical control will be a key enabling technology. ODIS proposes a monolithic IC solution based upon novel optoelectronic (OE) thryistor circuit design. Thyristor/HFET circuits implement a novel power amplifier using a gated OE oscillator driving a Class E output. The receive channel is implemented with an photonic link based upon linear phase modulation and coherent detection which achieves an SFDR of -92dB and SNR of -149dB. The photonic receive link also implements narrow channel microwave filtering in the optical domain. The photonic technology also enables novel AD architectures for the back end conversion or for direct digitization after the LNA. The photonic insertion is in the form of monolithic integrated circuits and the fabrication technology includes high temperature (850C) processing which pre-qualifies it for the mil-spec environment. Elimination of oxides results in rad-hard circuits. The in-plane photonics simplifies the package.
