光子计算机（亦称光脑）是指以光子替代电子的先进计算机。數十年來的研究指出，光子可以比傳統電腦中使用的电子有更高的頻寬（例如光纖）。
大多数研究项目都专注于用光学等效模組替换当前的计算机组件，目的是要得到可以处理二进制数据的光学计算机系统。这种方法似乎为商业光学计算提供了最佳的短期前景，因为光学组件可以集成到传统计算机中，形成光电混合的系統。然而，光电设备因為将电能转换为光能再轉回電能，會損失30％的能量。此转换也会减慢消息的传输速度。全光学计算机不需要光学-电学-光学（OEO）转换，因此减少了对电力的需求[1]。
有些应用的设备，像是合成孔径雷达（SAR）和光学相关器，已可以用光学计算的原理來設計。例如可以使用相关器来检测和跟踪对象[2]，并对串行时域光学数据进行分类[3]。
