我们报道了一种单片生长的光寻址多量子阱空间光调制器，它具有高帧速率(>；44 kHz)和高灵敏度(50)，但以调制深度为代价。此外，通过使用电压脉冲，我们将器件的恢复时间从90ms缩短到1μS，从而实现了高帧频工作。我们仅用43 mW/cm~2连续写入光，就实现了对44 kHz反射读出光束60%的调制。
We report a monolithically grown optically addressed multiple-quantum-well spatial light modulator with high-frame rate operation (>44 kHz) and large sensitivity ( 50) can be achieved at the expense of modulation depth. In addition, by using a voltage pulse, we reduce the recovery time of the device from 90 ms to 1 μs such that high-frame rate operation can be achieved. We demonstrate 60% modulation of the reflected readout beam at 44 kHz by only using 43 mW/cm2 cw writing illumination.
