OCDMA Research
unique field-based optical communication test-bed designed and developed to investigate ultrahigh speed serial data rates transmissions and advanced Optical CDMA systems
test-bed connects CIDCOM Optics communication research laboratory at Strathclyde with the Rankine Building at Glasgow University
investigated the effects of residual dispersion on transmission channels when used by advanced optical CDMA systems
Novel technique was developed to enable control wavelength power redistribution within 2D-OCDMA codes which are based on wavelength hopping (WH) and time spreading (TS)
successfully tested in a multi user environment under real life conditions during our field trial experiments
the bit error rate measurements showed a 1.5dB improvement in the system performance

impedance spectroscopy of biological cells provides tool for monitoring cell growth and characteristics
using microelectrodes and a larger reference electrode
conducting polymers (PEDOT) electrodes instead of metal electrodes
PEDOT benefit from the material characteristic of transparency, low cost, biocompatibility, and lower interfacial impedance
enhances sensitivity

Results Gold and PEDOT
comparison Gold electrodes show very
large impedance at lower frequencies compared to the PEDOT electrodes
Impedance of the gold electrode reduces the sensitivity of cell impedance measurement and increases influence of noise. Cell growth experiment on PEDOT
cells growing on the surface at three different frequencies over 3 days
changes at lower frequencies is most prominent. As cells spread and divide they will gradually cover more of the measuring electrode resulting in an increase in the impedance.
