The self-linearized self-electro-optic-effect-device (SL-SEED) phenomenon observed with a quantum-well modulator and photodiode serial combination is one of the few practical routes to optical subtraction. A family of optical lateral inhibition architectures based on the SL-SEED that incorporate optical feedback is introduced and their operation confirmed in simulation. A successful experimental demonstration based on these ideas, performing edge-contrast enhancement by lateral inhibition, is described. System interconnections are both optical and electrical, with nonlocal interconnections being made optically by the use of diffractive elements.
用量子阱调制器和光电二极管串联组合观察到的自线性化自电光效应器件（SL-SEED）现象是实现光学减法的少数实用途径之一。介绍了基于SL-SEED并结合光反馈的一系列光学侧向抑制架构，并在模拟中证实了它们的运行情况。描述了基于这些想法的成功实验演示，即通过侧向抑制实现边缘对比度增强。系统互连既有光学的也有电气的，非局部互连通过使用衍射元件以光学方式实现。
