<div>I am trying to simulate the Hong-Ou-Mandel effect, and for that, I need <span style=”background-color: #bfedd2;”>qINTERCONNECT<\/span>. I used the following code in Python:<\/div><div><div> <\/div><div>import sys<\/div><div>sys.path.append(r”C:\\Program Files\\Lumerical\\v241\\api\\<wbr>python”)<\/div><div> <\/div><div>import qinterconnect<\/div><div>from qinterconnect.solver import QSolver<\/div><div>from matplotlib import pyplot as plt<\/div><div>import numpy as np<\/div><\/div><div> <\/div><div> <\/div><div>But I get this error :  ModuleNotFoundError: No module named ‘qinterconnect.solver'<\/div><div> <\/div><div><p>I have attached a screenshot from the Program Files<\/em> Lumerical folder, which shows that it seems Python API module for qINTERCONNECT is installed. However, it does not appear to contain any solver, such as QSolver, so I am unsure if this error is related to that.<\/p><p>          <\/p><p>Additionally, I have attached a screenshot from the Ansys Lumerical Launcher, which shows that I have access to qINTERCONNECT. However, when I try to open this solver, I only see a command window instead of a specific interface GUI, like with the other solvers. I have attached this screenshot as well.<\/p><p><\/p><p>I would appreciate it if you could let me know how I can resolve this issue.<\/p><p> <\/p><p>In the meantime, I tried using INTERCONNECT to simulate the Hong-Ou-Mandel effect, but it seems unable to solve it and returns values in the classic view. Although I used an attenuator with -80 dB, I still could not observe the Hong-Ou-Mandel effect in the output.<\/p><\/div><div>I have attached my setup screenshot in interconnect, I used optical oscilloscopes in both outputs and also tried optical power meters in both outputs. I see the same result from both outputs and I could not observe the HOM effect.<\/div><div> <\/div><div><\/div><\/p>\n","protected":false},"template":"","class_list":["post-392662","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
