Abstract

Silicon micro-ring resonator-based generation of all-optical (2×2) Walsh–Hadamard code is proposed. The energy-efficient, ultra-high-speed, and compact nature of micro-ring resonator-based devices is essential for optical computing. Both MATLAB and the Ansys Lumerical finite difference time domain (FDTD) approach are used to implement the generation of all-optical (2×2) Walsh–Hadamard code. The proposed design is simulated at about 260 Gbps. In the recommended circuit, the needed pump power for switching is merely 0.84 mW, which is extremely little in contrast. The “figure of merits” of the proposed design is evaluated through numerical simulation. The obtained contrast ratio and extinction ratio are considerably greater at 25.24 and 14.63 dB, respectively. On the other hand, the achieved amplitude modulation of 0.13 dB is extremely low. The on-off ratio for a single micro-ring resonator is 36.9 dB.

利用硅微环谐振器生成全光沃尔什-哈达玛德码

提出了基于硅微环谐振器生成全光（2×2）沃尔什-哈达玛码的方法。基于微环谐振器的器件具有高能效、超高速和紧凑的特性，这对于光学计算至关重要。MATLAB 和 Ansys Lumerical 有限差分时域 (FDTD) 方法被用于实现全光 (2×2) 沃尔什-哈达玛代码的生成。对拟议设计进行了约 260 Gbps 的模拟。在推荐的电路中，开关所需的泵功率仅为 0.84 mW，相比之下微不足道。通过数值模拟评估了拟议设计的 "优点"。所获得的对比度和消光比分别为 25.24 和 14.63 dB，都大大提高了。另一方面，0.13 dB 的振幅调制非常低。单个微环谐振器的开关比为 36.9 dB。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
