摘要: An electro-optic (EO) device having a high-resistivity semiconducting crystal and a method of operating such a device. The local shielding of the externally applied field lowers the EO effect, which can be partially or completely inhibited particularly in the low-frequency regime, i.e., less than about 105 Hz. By holding a high-resistivity semiconducting crystal at a suitable temperature, EO response and efficiency are improved, in particular for light signals that are non-modulated or modulated at low frequencies. Preferably, the temperature at which the semiconducting crystal is held during functioning is between 50 and 150° C. Enhancement of the EO effect has been demonstrated also for EO devices operating at relatively large optical powers, i.e., larger than about 0.1 mW.
