Embodiment Construction
[0039] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0040] In order to meet the needs of indoor communication, the electro-optical response rate of the optical modulator needs to be high enough. If 1MBaud / s is to be achieved, the total response time (rising edge time + falling edge time) of the single electro-optical effect of the modulator is required to be less than 1μs, (that is, at least 10^6 "rising and falling" operations can occur per second ). At present, the response time in the field of smart glass research is basically above ms, which obviously cannot meet the communication requirements. Therefore, it is necessary to seek electro-optical materials with high response rate (that is, faster response to voltag...
