Title: | High extinction ratio magneto-optical fiber modulator based on nanoparticle magnetic fluids | Authors: | Dong, Xinyong Chen, Li Han Wong, Wei Chang Zu, Peng Chan, Chi Chiu Lew, Wen Siang Jin, Yongxing Liew, Hwi Fen |
Issue Date: | 2012 | Series/Report no.: | IEEE photonics journal | Abstract: | A novel magneto-optical fiber modulator with a high extinction ratio (ER) based on a polarization interference structure is proposed. A magnetic fluid (MF) film and a section of a polarization-maintaining fiber (PMF) are inserted into the structure to generate a suitable sinusoidal interference spectrum for light modulation. The MF film leads to a spectrum shift under external magnetic field due to its magnetically controllable birefringence, whereas the PMF is used to control the period of the interference spectrum. In this experiment, magneto-optical modulation with a high ER of 38 dB is demonstrated. | URI: | https://hdl.handle.net/10356/98962 http://hdl.handle.net/10220/13462 |
