Current local area network (LAN) bandwidth demands of> 1 Gb/s are pushing the limit of the
bandwidth-distance product of multimode fiber, the predominant fiber in LAN backbones. In …

A high-density wavelength division demultiplexer (DEMUX) capable of demultiplexing eight-
channel 200-GHz optically spaced signals into a 62.5-µm multimode-fiber array is reported …

The theoretical model used by Gigabit Ethernet to develop the optical physical layer
specifications is presented. The model calculates the penalties associated with using laser …

We demonstrate a fast, all-optical polarization gate in a room-temperature atomic medium.
Using a Polarization-Selective-Kerr-Phase-Shift (PSKPS) technique, we selectively write a π …

Many medical, environmental, and industrial sensing applications could take advantage of
uncooled temperature-stable optical sources that are incoherent and un-polarized as such …

We demonstrate an observation of zero to π continuously controllable cross-phase-
modulation based on an N-type electromagnetically-induced-transparency scheme in a …

Summary form only given. Due to the increasing demand for high-bandwidth applications,
multi-processor systems and communication systems are demanding very low cost, high …

We develop a hybrid scheme of cross phase modulation based on electromagnetically
induced transparency (EIT) and active Raman gain (ARG) in a multi-level atomic medium …

We propose a dynamic lossless all-optical polarization gate using coherently prepared
atomic media. We show that the loss/gain of two circularly polarized components of a …

We describe the design and performance of a multimode 8-channel, 200 GHz-spaced dense
wavelength division demultiplexer using a high order blazed grating. The mean insertion …
