The inverted wavelength conversion of the nonreturn to zero and the format conversion from NRZ to pseudo return to zero are demonstrated synchronously based on single SOA and an optical bandpass filter with 0.32 nm bandwidth. The conversion results depend on the OBF detuning as respect to the probe carrier.
利用半导体光放大器和带宽为0.32 nm的可调窄带滤波器同时实现了40 Gbit/s的非归零信号的反相波长转换和非归零到伪归零信号的码型转换，波长转换和码型转换的结果差异取决于滤波器中心波长相对于探测光波长的失谐量。
From the experiment results, the elliptical patch-fed and inverted trangle-fed U-shaped dielectric resonator antennas have 72% and 84% impedance bandwidths, respectively. These bandwidth performances keep advanced level in the world. Secondly, a high-isolation dual-polarization dielectric resonator antenna is developed.
实验结果表明，采用椭圆形贴片馈电和采用倒三角形贴片馈电的U形介质谐振器天线的相对阻抗带宽分别达到72%和84%，处于国际先进水平。第二，研制了高隔离度双极化介质谐振器天线。
By comparing the data we can see that inverted trapezoid ridge waveguide has the biggest cutoff wavelength and single-mode bandwidth, it is more conducive to miniaturization devices design of microwave.
