SUMMARY
The discussion centers on the advantages of using single mode (SM) waveguides for sensing applications involving evanescent fields. Participants highlight that SM waveguides simplify optical paths, reducing interference caused by multiple modes in multimode fibers. The consensus is that while multimode fibers can complicate signal integrity due to varying optical path lengths, SM waveguides ensure efficient power transfer and minimize light dispersion, particularly when interfacing with single mode fibers and grating couplers.
