Analog-to-digital converters (ADCs) are an essential component of digital receiver systems. Progress at advancing the electronic ADC modules has been very slow due in large part to the difficulties in fabricating the electronic circuitry required for

A mode-locked erbium-ytterbium fiber laser operating at 1550 nm using multiple quantum well (MQW) saturable absorbers was developed. The laser was constructed in a Fabry-Perot configuration using a fiber Bragg grating as a front reflector and a fiber

There has been much recent interest in the use of photonics for analog to digital conversion. It is anticipated that the use of photonic analog to digital converters (ADCs) will far surpass the performance of electronic ADCs in terms of both sampling

Because of its well known electrochromic and photochromic properties, and its relative ease of large scale manufacture, tungsten oxide has long been a candidate for display applications. This use was first suggested by Deb in 1973, and numerous paten

We have constructed and tested a spin stand based demonstration system for a new form of optical memory. Based on a new two color storage process which utilizes a form of tungsten oxide as the physical medium, this system offers potential advantages
We present an adaptive opto-electronic neural network hardware architecture capable of exploiting parallel optics to realize real-time processing and classification of high-dimensional data for Air Force Hostile Target Identification (HTI). This arch

A version of an image consisting of multiple wavelet scales allows for more flexible feature extraction when compared to the use of one wavelet scale. We proposed an imaging system based on a multiple-input joint-transform correlator, that could be u

A multispectral version of an image consisting of multiple wavelet components allows for more flexible feature extraction when compared to the use of one wavelet component. We showed how a multiple-input joint wavelet- transform correlator could be u
