摘要： An improved waveguide shuttle optical switch design which provides the function of a variable optical attenuator (VOA). A small degree of intentional misalignment of the waveguide will create different levels of optical attenuation. By finely controlling the misalignment of a selected switched position, a single device may be realized that will provide the functions of both switching and attenuating or just attenuation alone. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning a waveguide shuttle platform. The integration of the switching function and the VOA function reduce the optical loss which is otherwise unavoidable when the inevitable alternative of a separate switch and a separate VOA must necessarily be employed. The resultant improved device can also be applied for correcting the difference in optical intensity created by the manufacturing tolerances inherent in the fabrication of array waveguide gratings.
摘要翻译：提供了可变光衰减器（VOA）的功能的改进的波导穿梭光开关设计。波导的有意的不对准会导致不同程度的光衰减。通过精细地控制所选择的切换位置的未对准，可以实现单个设备，其将提供单独切换和衰减或仅仅衰减的功能。光学MEMS器件利用与用于对准波导穿梭平台的热驱动致动器相关联的闭锁机构。开关功能和VOA功能的集成减少光损耗，否则当必须采用单独的开关和单独的VOA的不可避免的替代方案时，光损失是不可避免的。所得到的改进的器件还可以用于校正由阵列波导光栅的制造中固有的制造公差产生的光强差。

摘要： First and second ridge type photonic waveguides are provided. Each of the waveguides includes a core layer and a reflective cladding layer in continuous contact with a first side of a core layer. The core layer has a core index of the refraction and is formed in a ridge in a dimension and shape to impose lateral confinement. The reflective cladding layer has an index of refraction that is substantially different than the core index of refraction. An inter-waveguide slab portion is provided between the first and second waveguides. A substrate supports the first and second waveguides, the slab portion, and the reflective cladding layer. A light interceptor region is provided to hinder a transfer of photons between the first and second waveguides through the inter-waveguides slab portion. The light interceptor region may include a trench region, which is an air gap in one embodiment.
