Abstract

We describe, demonstrate, and characterize an analog self-electro-optic-effect device that gives a difference between two optical output powers that is linearly proportional to an electrical or an optical drive. Such a device should permit bipolar (positive and negative) processing in novel image processing arrays. The device is able to operate over a range of more than 4 orders of magnitude of optical power from 50 nW to 2.5 mW, corresponding to uniform incident intensities as low as 3.3 mW/cm(2). The frequency response (3-dB limit) varies linearly from 7 kHz at 1-µW absorber power to 3.5 MHz at 1 mW of absorbed powers.

摘要

我们描述、展示并表征了一种模拟自电光效应器件，该器件产生的两个光输出功率之差与电驱动或光驱动成线性比例。这样的器件应能在新型图像处理阵列中实现双极（正和负）处理。该器件能够在50 nW至2.5 mW的超过4个数量级的光功率范围内工作，对应低至3.3 mW/cm²的均匀入射强度。频率响应（3分贝限制）在吸收器功率为1 μW时从7 kHz线性变化到吸收功率为1 mW时的3.5 MHz。
