A comparative study of the performance of seven- and 63-chip optical code-division multiple-access encoders and decoders based on superstructured fiber Bragg gratings [PDF]

, 2001
We report a range of elementary optical coding and decoding experiments employing superstructured fiber Bragg grating (SSFBG) components: first, we perform a comparative study of the relative merits of bipolar and unipolar coding: decoding schemes and ...

Thin bonding wires temperature measurement using optical fiber sensors [PDF]

, 2011
In this work we demonstrate the use of optical fiber sensors to measure temperature in thin metallic bonding wires. Temperature was measured in copper wires with diameter of 0.10, 0.28, 0.60 and 0.70 mm and for different values of the driven electrical ...

Analysis of double-parallel amplified recirculating optical-delay lines [PDF]

, 1994
A novel method of analysis of double-parallel amplified recirculating optical-delay lines (DPAROD) is presented. The location of the maxima and the minima of the transfer function for this configuration is calculated and experimentally demonstrated.

Remote downconversion scheme for uplink configuration in radio/fiber systems [PDF]

, 2005
The authors present a novel technology for uplink transmission in radio over fiber (RoF) distribution systems. The technique employs remote downconversion of the uplink data to intermediate frequency (IF) in the base station (BS).

Efficient all-optical wavelength conversion scheme based on a saw-tooth pulse shaper [PDF]

, 2009
We experimentally demonstrate the use of saw-tooth optical pulses, generated using a superstructured fiber Bragg grating, to achieve high performance and efficient all-optical wavelength conversion in a scheme based on cross-phase modulation in a highly ...

All-optical TDM data demultiplexing at 80 Gbit/s with significant timing jitter tolerance using a fiber Bragg grating based rectangular pulse switching technology

, 2003
We demonstrate the use of fiber Bragg grating based pulse-shaping technology to provide timing jitter tolerant data demultiplexing in an 80 Gb/s all-optical time division multiplexing (OTDM) system. Error-free demultiplexing operation is achieved with ~6

Dispersion controlled highly nonlinear fibers for all optical processing at telecoms wavelengths [PDF]

, 2010
We review our recent progress in the development of lead silicate glass fibers with high nonlinearity and tailored near-zero dispersion at telecommunication wavelengths, encompassing holey, all-solid microstructured and W-type fiber designs.
