Mwk. Mak et Hk. Tsang, Polarisation-insensitive widely tunable wavelength converter using a single semiconductor optical amplifier, ELECTR LETT, 36(2), 2000, pp. 152-153
A polarisation-insensitive wavelength converter using four-wave mixing (FWM
) in a semiconductor optical amplifier (SOA) has been realised. The convert
er uses a novel polarisation-diversity scheme which requires only one SOA.
Polarisation-insensitive wavelength conversion (< 1dB polarisation sensitiv
ity) and a near constant (< 3dB variation) conversion efficiency was achiev
ed over a range of 26nm.
