描述了所提出的全光模数 (A/D) 转换器的集成。为了实现高速、高吞吐量的系统，光学A/D转换引起了人们的广泛关注。 A/D转换一般由采样、量化和编码三个过程组成。尽管光学采样技术已经实现，但对光学量化和光学编码技术的研究还很少。我们之前提出了一种同时实现光量化和光编码的全光A/D转换器。在本文中，我们集成了所提出的全光A/D转换器以提高其性能和稳定性。我们验证了由短高非线性光纤、阵列波导光栅和可变光衰减器组成的集成全光A/D转换器的运行。
Integration of a proposed all-optical analog-to-digital (A/D) converter is described. To realize a high-speed and highthroughput system, optical A/D conversion has attracted much attention. A/D conversion generally consists of three processes of sampling, quantization and coding. Whereas an optical sampling technique has already been realized, there have been few investigations on the optical quantization and optical coding technique. We previously proposed an alloptical A/D converter which realizes both optical quantization and optical coding. In this paper, we integrate the proposed all-optical A/D converter to improve its performance and stability. We verify the operation of the integrated all-optical A/D converter composed of a short high nonlinear fiber, arrayed waveguide gratings and variable optical attenuators.
