Improving Channel Uniformity of Multiplexer with High-Degree-of-Freedom Auxiliary Waveguides

Optics
In order to further mitigate the channel non-uniformity at the junction between the input slab and the arrayed waveguide grating in traditional AWG structures, we design a highly flexible, structurally adaptive linear auxiliary waveguide.

Ultra-Wideband RF-Photonics Technology for Microwave Spectrometry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
We describe an RF-photonic system architecture to measure microwave spectrum over a wide bandwidth with high resolution. The approach relies on the up-conversion of the electronic signal to the optical domain using a high-speed electro-optic modulator ...
