Abstract

We demonstrate four wave mixing (FWM) based wavelength conversion of 40 Gbaud differential phase shift keyed (DPSK) and quadrature phase shift keyed (QPSK) signals in a 2.5 cm long silicon germanium waveguide. For a 290 mW pump power, bit error ratio (BER) measurements show approximately a 2-dB power penalty in both cases of DPSK (measured at a BER of 10(-9)) and QPSK (at a BER of 10(-3)) signals that we examined.

摘要

我们展示了在一条2.5厘米长的硅锗波导中基于四波混频（FWM）的40吉波特差分相移键控（DPSK）和正交相移键控（QPSK）信号的波长转换。对于290毫瓦的泵浦功率，误码率（BER）测量表明，在我们所研究的DPSK（在误码率为10^(-9)时测量）和QPSK（在误码率为10^(-3)时）信号的两种情况下，功率代价均约为2分贝。
