摘要:
A method of forming a grating in waveguide uses an ion exchange process to provide a waveguide region within and clad by a surrounding substrate and through an ion exchange process diffusing into the substrate an ion, such as such as Ag+ that is photosensitive and that provides a refractive index difference from adjacent non-diffused regions of the substrate. After the diffusion process, the step of exposing at least some of the waveguide region to light having a suitable intensity and duration to provide a permanent index change within regions of the waveguide region to form a grating is performed.
摘要(中):
在波导中形成光栅的方法使用离子交换工艺来在周围的衬底内部提供波导区域并且由周围衬底包围,并且通过离子交换工艺将离子扩散到衬底中,例如Ag +等离子是光敏的,并且提供 与衬底的相邻非扩散区域的折射率差。 在扩散处理之后,执行将至少一些波导区域暴露于具有适当强度和持续时间的光以在波导区域的区域内提供永久折射率变化以形成光栅的步骤。
