Abstract

Nonresonant-type Bi₂O₃-B₂O₃-SiO₂ glass containing high concentration of Bi₂O₃ was prepared by a melting method. Optical Kerr shutter switching and degenerated four wave mixing experiments for this glass were performed using femtosecond laser. This glass exhibited ultrafast response below 150 femtosecond in optical Kerr switching operation. Moreover, THz optical switching was successfully performed with this glass using 1.5 THz pulse train as the gate beam. Ultrafast response and high threshold for optical damage were also confirmed with this glass at the communication wavelength of 1.5 micrometers . These results indicate that high speed switching beyond THz can be realized using Bi₂O₃-glass.
