Abstract

The cascaded χ⁽²⁾ process is an effective wavelength conversion technique, due to its excellent characteristics such as transparency to bit rate and data format [1]. Obtaining efficient wavelength conversions in this method requires a tunable high power (~1W) pumping source [1]. It would be preferable to reduce the cost and complexity of pump sources from a practical network manufacturability standpoint. In this report, we propose and demonstrate an intra-cavity scheme containing a quasiphase-matched (QPM) LiNbO₃ waveguide as a wavelength converter and an erbium doped fiber amplifier (EDFA) as a pump source.
