Abstract

This paper presents photo-induced signal taps for power monitors in planar lightwave circuits. Both periodic perturbation and non-periodic perturbation structures are discussed. The numerical models based on the volume current method are used to simulate the interaction of guided light with photo-induced periodic and non-periodic perturbations. The results are compared with those from a commercially available FDTD simulation tool. The optimized designs for the minimized polarization dependent loss taps are presented. Contrary to the power monitors currently used in planar lightwave circuits, which are based on directional coupler and deep etch technology, we propose the signal taps through photosensitive processes using laser light. Our approach is more cost efficient, flexible and reliable.
