| 摘 要： | 提出了一种利用单通道反射型聚合物电光调制器同时调制不同路光的方法。衰减全反射结构的电光调制器,其每一个衰减全反射(ATR)峰的位置分别对应于一个导波共振模式。实验系统中利用衰减全反射导膜峰作为调制通道,使其每一路光路的入射角分别对应于不同导波共振模式的工作角,就可以实现利用单通道的电光调制器同时调制不同路光。提出了三种实现两路光同时调制的模式,并给出了三种模式的调制结果。结果表明,作为调制通道的导模阶数越低,调制效率越高。在832 nm光波波长下,采用最低阶导模进行调制时可以获得42.9%的调制效率。

| Abstract: | A new method by which several light beams can be synchronously modulated based on attenuated total reflection(ATR) polymer electrooptic modulator with single pair of electrodes is proposed.Absorption peaks of ATR are corresponding to waveguide resonance modes,respectively.In the experimental system,the absorption peaks of ATR are used as the modulation channels.Several light beams can be modulated simultaneously through that every incident angle is related to a work angle of different waveguide resonant modes,respectively.Double-channel modulation results using three modulation types have been demonstrated.Results show that the lower guide mode acting as the modulation channel is,the larger modulation index can be obtained.42.9% modulation efficiency can be obtained when the lowest guide mode acts as the modulation channel at the 832 nm wavelength. |
