A compact optical heterodyne interferometer by optical integration and its application
Autor: Akira Taniguchi, Isao Kobayashi, Koichiro Miyagi, Masaya Nanami
Publikováno v: Optical Review. 4:A133-A137
A compact high-resolution optical heterodyne interferometer combining a two-frequency light module and a minute optical system is described. The light module, which generates two independent frequencies of light, is fabricated by proton exchange meth

Ultra-long-distance (230 km) FBG sensor system
Autor: Yoshifumi Takahashi, Koichiro Miyagi, Hiroyuki Iida, Kenichi Nakamura, Yoshimitsu Iki, Takanori Saitoh
Publikováno v: SPIE Proceedings.
An ultra-long-distance Fiber Bragg Grating (FBG) sensor system using a high-speed swept-wavelength light source (HSLS) is proposed and demonstrated. The light output of the HSLS is amplified and turned on and off, and its timing is synchronized to th

Long-Distance FBG Sensor System Using High-Speed Swept-Wavelength Light Source
Autor: Koichiro Miyagi, Yoshifumi Takahashi, Hiroyuki Iida, Yoshimitsu Iki, Takanori Saitoh, Kenichi Nakamura
Publikováno v: Optical Fiber Sensors.
A long-distance FBG sensor system using a power controlled high-speed swept-wavelength light source is proposed and demonstrated. This system can measure FBGs reflection wavelengths even if the FBGs are located at a 100 km distance.

High-speed MEMS swept-wavelength light source for FBG sensor system
Autor: Yoshifumi Takahashi, Koichiro Miyagi, Takanori Saitoh, Kenichi Nakamura
Publikováno v: SPIE Proceedings.
A high-speed MEMS swept-wavelength light source (SLS) for an FBG sensor system is proposed and demonstrated. It is basically a multi-mode external-cavity laser diode (LD), and consists mainly of an LD head, diffraction grating, and electromagneticall

Nondegenerate Four-Wave Mixing in Tensile Strained MQW Semiconductor Optical Amplifier
Autor: Atsushi Yamada, Yuko Yamaguchi, Toshinobu Otsubo, Koichiro Miyagi, Akira Taniguchi
Publikováno v: Nonlinear Guided Waves and Their Applications.
To realize an ultrahigh speed optical transmission system, applications of nonlinear phenomena have recently been investigated for optical DEMUX with four-wave mixing(1), (2) or dispersion compensation(3). If an optical fiber is employed as a nonline

Optical Frequency Comb Generation with an Optical Loop
Autor: Koichiro Miyagi, Shigeru Kinugawa, Takanori Saitoh, Shigenori Mattori
Publikováno v: Japanese Journal of Applied Physics. 37:L927
We propose a novel method using an optical loop system to expand the span of an optical frequency comb. The validity of this system was confirmed experimentally in the 1.5 µm wavelength region. By using this system, the modulation index was doubled.
