Tunable optical wavelength conversion of OFDM signal using a periodically-poled lithium niobate waveguide

Opt Express. 2009 May 25;17(11):9177-82. doi: 10.1364/oe.17.009177.

Abstract

We experimentally demonstrate tunable optical wavelength conversion of a 10-Gb/s radio frequency (RF)-tone assisted orthogonal-frequency-division-multiplexing (OFDM) signal with approximately-5 dB (approximately 30%) efficiency over approximately 30 nm bandwidth using a periodically-poled lithium-niobate (PPLN) waveguide. A penalty of < 3 dB is obtained after wavelength conversion. Quadrature amplitude modulation (QAM) size and subcarrier number are varied to further evaluate the performance of the wavelength converter.
