Hi Lumerical’s Community
I would like to build a optical beamformer network. My purpose is to mix an microwave signal 10[GHz] with a laser signal 193.1[THz]. Then, the optical signal is divided in channels and each channel has a different delay due to ring resonators. I have four output channels. Then the optical signal of each output is transformed to a microwave signal due to a PIN photodetector. I would like to measure the group delay of the microwave signal of each output.
I have build the optical beam forming network with single bus ring resonators and the optical group delay is quite good.
I would like to ask how I can use the “Network Analyzer” in INTERCONNECT to plot the group delay of the microwave signal.
Also, I tried to connect the output of the “Network Analyzer” to the port of laser for modulation. The “Network analyzer” has 4 input, one of each PIN. Could you please check this? Can i use this “Network Analyzer” to mix and plot microwave signal?
Moreover, after run the simulation, there is an error
What is “Deadlock condition detected”?
If it is needed I can upload the optical beam forming network that I have built.
