Opt Express 16:1460-5. 2008..The lasing wavelength can be switched individually by controlling the polarization controller and the cavity loss...
- Strain and temperature sensitivities of an elliptical hollow-core photonic bandgap fiber based on Sagnac interferometerGilhwan Kim
Photonics Research Lab, Korea Institute of Science and Technology, 39 1 Hawolgok Dong Seongbuk Ku, Seoul 136 791, Republic of Korea
Opt Express 17:2481-6. 2009..The strain and temperature sensitivities were very much dependent upon the wavelength. Moreover this PBGF-based interferometer can be a good sensor of physical parameters such as strain and temperature...
