Self-pumped wide range wavelength converter

A new broadband orthogonal pump (BOP) four wave mixing (FWM) wavelength conversion scheme was demonstrated. The implemented set up shown conversion efficiencies higher than -20 dB and with less than 3 dB variation, for different conversion wavelengths. It is also more stable and cost effective when comparing to other BOP FWM wavelength conversion techniques, due to the reduction of the number of devices needed. The tunability of the HiBi fibre ring cavity Bragg grating structure (FBGS) along with the bit-error rate measurements for this wavelength converter is under investigation and will be reported.
