提出了一种用于光分组交换的紧凑型4×8波长路由开关，它单片集成了快速可调谐波长转换器(TWCS)和阵列波导光栅(AWG)。TWC由一个双环形谐振器耦合的可调谐激光器和一个基于并行放大器结构的光学门组成，该可调谐激光器允许快速而稳定的开关，该结构防止输入光信号通过AWG(无滤波操作)路由。AWG和环形谐振器采用深脊波导技术，简化了开关的制作，使器件更加紧凑。无滤波的TWCS实现了输入光信号的低串扰，低于-22分贝。实现了10Gbit/S的非归零信号的波长路由操作，开关时间小于5 ns。
We present a compact 4x8 wavelength-routing switch that monolithically integrates fast tunable wavelength converters (TWCs) and an arrayed-waveguide grating (AWG) for optical packet switching. The TWC consists of a double-ring-resonator-coupled tunable laser which allows rapid and stable switching, and an optical gate based on a parallel amplifier structure which prevents an input optical signal from being routed through the AWG (filter-free operation). A deep-ridge waveguide technology, employed for the AWG and ring resonators, facilitates the fabrication of the switch and makes the device compact. The filter-free TWCs achieve low crosstalk of the input optical signal of less than -22 dB. The wavelength routing operation of a non-return-to-zero (NRZ) signal at 10 Gbit/s is achieved with a switching time of less than 5 ns.
