Ring Resonators are key component in modern optical networks. Their size allows high density integration in optical photonic circuits due to the use of high index contrast. Ring Resonators based filters in wavelength ...

A cheap, scalable and efficient optical wavelength conversion and optical path switching technique for access networks is experimentally demonstrated. Wavelength conversion is used in wavelength division multiplexed (WDM) ...

Optical networks that apply the technology of dense wavelength-division multiplexing (DWDM) have recently resulted in a considerable increase in existing telecommunications infrastructures. They are expected to play a ...

We experimentally investigate the sensitivity of PMF and LEAF fibre. The design of a stress sensor gave the best sensitivity of 0.051 kg -1 while that of a temperature sensor, gave the best sensitivity of 0.181 0C1

We experimentally investigate the effects of increase of the differential group delay (DGD) on Raman gain and gain value. It was found that the increase of DGD values lead to the formation and the increase in the number ...

In this paper, we experimentally present a novel, all-optical spectral efficient vertical-cavity surface-emitting laser- (VCSEL-) based technique for routing and spectrum assignment in optical networks. Exploiting all ...

The transmission of signals in long-haul optical fibre systems requires signal amplification. Raman amplification is based on SRS and it requires a frequency shift of 13.2 THz provided by signal and pump wavelengths of ...

For the first time, we demonstrate, VCSEL-to-VCSEL wavelength conversion within the low attenuation 1550 nm transmission window, including transmission over fibre and bit error rate (BER) performance characterization. ...
