Logic-Operated Mathematical Morphology and Its Optical Implementation

October 1999 · Applied Optics

Logic-operated mathematical morphology (LOMM) was studied in detail. It combines morphological operations and logical operations between image and structuring element (SE) in one simple direct step. A total of 12 LOMM operations are obtained. Only dilation and erosion can be realized directly by optical convolution followed by thresholding, whereas the operation set provides three types of basic ... [Show full abstract] operation, which can be realized directly by optical extended convolution followed by thresholding in one step. The multiply between image and SE in a convolution is extended into 16 logic operations.

DEMOUNTABLE SINGLE-FIBER OPTIC CONNECTORS AND THEIR MEASUREMENT ON LOCATION.

July 1978

The transfer-molded, single-optical-fiber connector and the fiber-guide distribution syStem implemented for the Atlanta Fiber System Experiment are described. A new technique for measuring the connector and connectorized fiber cable loss in the field was implemented and the results are reported. More recent results of the evolutionary versions of the connector are also reported.

Real-Time Coherent Optical OFDM Receiver at 2.5-GS/s for Receiving a 54-Gb/s Multi-band Signal

March 2009

We demonstrate the real-time implementation of a FPGA-based coherent optical OFDM (CO-OFDM) receiver at 2.5-Gsamples/s, which successfully receives a subband of a 54-Gb/s multi-band CO-OFDM signal with a record-low error floor of 3.7x10-8.

Implementation of Guided-mode Resonance Optical Filter Using Two-step Nanoimprinting Process

January 2016

We propose two-step nanoimprinting process to reduce the modulation depth of a guided mode resonance grating structure and to implement narrow band optical filters. Experimental results show that this method with good reproducibility and a notch filter with a spectral FWHM of 0.9 nm was achieved.

Luminous flux ring mixer

September 2016

LED modules emitting a luminous flux, implement near-field luminance distribution or colorimetric distribution depending on emitters location. In the far field there is complete mixing of luminous flux, both in terms of quantity as well as because of distribution color parameters. To achieve these mixing light in a short distance of the LEDs is necessary to use optical elements. The article ... [Show full abstract] presents the results of creating light distribution and luminance by using the ring optical elements.

A New On-Chip Voltage Converter for Submicron High-Density DRAMs

January 1986

A new on-chip voltage converter has been developed, and its characteristics have been examined. Being implemented in an experimental 4Mb dynamic RAM, this voltage converter has successfully demonstrated to be of importance for high-density, high-speed, and high-reliability DRAMs with submicron transistors.

May 2008

We implemented a photon-counting optical receiver using a periodically-poled lithium niobate waveguide and an emulated array of silicon Geiger-mode avalanche photodiodes. We achieved a sensitivity of < 0.5 detected photons/bit at 187.5 Mb/s.

FPGA implementation of concatenated non-binary QC-LDPC codes for high-speed optical transport

June 2015 · Optics Express

In this paper, we propose a soft-decision-based FEC scheme that is the concatenation of a non-binary LDPC code and hard-decision FEC code. The proposed NB-LDPC + RS with overhead of 27.06% provides a superior NCG of 11.9dB at a post-FEC BER of 10<sup>-15</sup>. As a result, the proposed NB-LDPC codes represent the strong FEC candidate of soft-decision FEC for beyond 100Gb/s optical transmission ... [Show full abstract] systems.

Two Approaches of Implementing Fractional Correlation Operation

July 2010

This paper concerns mainly about two approaches to implement the anamorphic fractional correlation operation. Firstly, the definition of anamorphic fractional correlation is introduced. Secondly, an optical approach of implementing the correlation operation is presented. Lastly, since the optical implementation is somewhat troublesome, we will show how to exploit the anamorphic fractional ... [Show full abstract] correlation by computer-generated holography.

Implications of interconnection theory for optical digital computing

September 1992 · Applied Optics

Heat removal, rather than finite interconnect density, is the major mechanism that limits how densely we can pack three-dimensional computing systems of increasing numbers of elements. Thus highly interconnected approaches can be employed without a further increase in system size. The use of optical interconnections for implementing the longer connections of such systems is advantageous. In fact, ... [Show full abstract] if the optical communication energy is sufficiently low and large-bit repetition rates are employed, conductors are useful for only the shortest connections and can be dispensed with altogether with little disadvantage. This justifies consideration of an optical digital computer.
