我们讨论了结构光接收机的概念设计，这些结构光接收机可以缓解光子匮乏的光通信中对高峰均功率比的要求。其基本思想是通过光干涉在接收机侧发射能量集中在单个时间间隔内的适当调制的相干光脉冲序列。给出了结构化接收机的两个可伸缩体系结构的例子。第一种是基于有源极化开关，将由二进制相移键控(BPSK)星座组成的Hadamard码字映射到标准脉冲位置调制(PPM)格式。第二接收机仅使用无源光学元件，将相干光脉冲的相位偏振模式转换成保持同步到达时间的单个脉冲。这样的转换使得能够实现等效于PPM方案但具有分布式光功率的通信协议，前提是符号间保护时间超过模式长度。

英文摘要：
  We discuss conceptual designs for structured optical receivers that can alleviate the requirement for high peak-to-average power ratio in photon-starved optical communication. The basic idea is to transmit sequences of suitably modulated coherent light pulses whose energy can be concentrated in a single temporal bin on the receiver side through optical interference. Two examples of scalable architectures for structured receivers are presented. The first one, based on active polarization switching, maps Hadamard codewords composed from the binary phase shift keying (BPSK) constellation onto the standard pulse position modulation (PPM) format. The second receiver, using solely passive optical elements, converts phase-polarization patterns of coherent light pulses into a single pulse preserving a synchronized time of arrival. Such a conversion enables implementation of a communication protocol equivalent to the PPM scheme but with distributed optical power provided that the intersymbol guard-time exceeds the pattern length.
