A compact chaotic laser device with a two-dimensional external cavity structure 砂田, 哲 安達, 正明 10463704 Sunada, Satoshi Fukushima, Takehiro Shinohara, Susumu Harayama, Takahisa Arai, Kenichi 50212519 Adachi, Masaaki Copyright © 2014 AIP Publishing LLC. We propose a compact chaotic laser device, which consists of a semiconductor laser and a two-dimensional (2D) external cavity for delayed optical feedback. The overall size of the device is within 230μm × 1 mm. A long time delay sufficient for chaos generation can be achieved with the small area by the multiple reflections at the 2D cavity boundary, and the feedback strength is controlled by the injection current to the external cavity. We experimentally demonstrate that a variety of output properties, including chaotic output, can be selectively generated by controlling the injection current to the external cavity. © 2014 AIP Publishing LLC. 金沢大学理工研究域機械工学系 AIP Publishing 2014-06-16 2018-01-11 eng journal article VoR https://doi.org/10.24517/00049735 http://hdl.handle.net/2297/00049735 https://kanazawa-u.repo.nii.ac.jp/records/43389 10.24517/00049735 10.1063/1.4883636 AA00543431 0003-6951 Applied Physics Letters 104 24 4883636 https://kanazawa-u.repo.nii.ac.jp/record/43389/files/TE-PR-SUNADA-S-4883636.pdf application/pdf 735.2 kB 2018-01-11
