首次在多量子阱定向耦合器中实现了与偏振无关的开关操作，条态串扰为-12 dB。通过在InGaAs-InP多量子阱中引入张应变，在耦合长度为1.2mm的情况下，与偏振无关的开关电压小至3V，在零电压下获得的跨态串扰对于TE和TM偏振光小于-8dB。<<ETX>>
Polarization-independent switching operation in a multi-quantum well directional coupler is obtained for the first time, with a bar-state crosstalk of -12 dB. By introducing tensile strain in an InGaAs-InP multi-quantum well, polarization-independent switching voltage is as small as 3 V, with the coupling length being 1.2 mm. The cross-state crosstalk that is obtained at zero-applied voltage, is less than -8 dB with respect to TE and TM polarized lights.<<ETX>>
