Light wave is of some attractive natures such as huge bandwidth, the possibility to control optical field 2D parallelly by optical free form surface and optical diffraction device. Such nature is very important to many applications such fiber telecommunications, high speed 3D sensing Lidar systems, and VR/AR components. In this talk, those optical devices based on the nature of light wave, including ultra-high speed DFB laser integrated with EA modulators, ultra-wide band lithium niobate thin film optical modulators, and ultra-high speed photodetectors, will be introduced.
