超紧凑的设备的几何形状，需要新的设备技术的发展是必不可少的光子晶体系统内的有源器件的成功实施。讨论了一种超小型硅基光子晶体光调制器的基本工作原理，该光调制器的截止频率与通信波长相关。开发了一种使用直接平行于光子晶体光调制器的重掺杂加热元件的高度局部化高温电阻加热的器件设计，并使用时域有限差分和有限元分析进行了评估。这些器件在1550 nm的电信波长周围的40 nm频带上表现出高消光比和低插入损耗，响应时间为几微秒到几微秒的量级。使用这些类型的设备的可靠性的影响进行了讨论。
Ultra-compact device geometries requiring the development of new device technologies are essential for the successful implementation of active devices within photonic crystal systems. The basic operation of an ultra-compact silicon-based photonic crystal light modulator actuated by the thermo-optic modulation of the cut-off frequency about the telecommunication wavelength is discussed. A device design using highly localized high temperature resistive heating of heavily doped heating elements situated directly parallel to the photonic crystal light modulator was developed and evaluated using finite difference time domain and finite element analysis. These devices exhibited high extinction ratios and low insertion losses over a 40 nm frequency band around the telecommunication wavelength of 1550 nm with response times on the order of a few to several microseconds. The reliability implications of using these types of devices are discussed.
