Nonlinear-Error-Free Optical Quantization Using Dense Spectral Slicing Takahiro KODAMA Ryosuke MATSUMOTO Akihiro MARUTA Tsuyoshi KONISHI Ken-ichi KITAYAMA Publication IEICE TRANSACTIONS on Communications Vol.E99-B No.3 pp.647-653 Publication Date: 2016/03/01 Online ISSN: 1745-1345 DOI: 10.1587/transcom.2015EBP3126 Type of Manuscript: PAPER Category: Fiber-Optic Transmission for Communications Keyword: arrayed waveguide devices, nonlinear optical signal processing, nonlinear optics fibers, Full Text: PDF(2MB)>>
Summary: We numerically and experimentally demonstrate for the first time a novel all-optical quantization technique using dense spectral slicing with a specially designed arrayed waveguide grating for orthogonal frequency division multiplexed signals. By using a mode-locked laser diode with low jitter, the quantization technique can be achieved a high-speed and low-jitter operation. Both numerical and experimental results confirm the feasibility of 10 GSample/s, completely linear 3-bit step quantization for photonic analog to digital conversion. This optical quantization technique will be beneficial for ultra-high-speed optical communication using digital signal processing. | |||||
