Optical Fiber to Diamond Waveguide Coupling

Hey forum members!
I try to simulate coupling between an optical fiber and a diamond nanobeam waveguide. For simplicity I simulated a 2D cross section of the 3D geometry. When I look at the norm of the electric field, coupling between the fiber and diamond waveguide can clearly be seen. However, when I look at the transmittance of port 1 to port 2, it gives a value of 0.0025 which is very low. Can anybody explain what went wrong in the simulation and why the value of the transmittance is so low?
The Comsol 5.5 version of the simulation is attached to this post. In addition, I attached an image of the electric field norm distribution over te whole cross section.
Best,
Thomas
