Practical Evaluation of Polymer Waveguides for High-Speed and Meter-Scale On-Board Optical Interconnects

We comprehensively evaluated optical characteristics, environmental stabilities, fiber optics compatibilities, and high-speed performances of multimode polymer waveguides fabricated in small batch with a length of 946 mm. The waveguides exhibit a low transmission loss (0.046 dB/cm at a wavelength of 850 nm), low interchannel crosstalk (≤ -58 dB), and a large misalignment tolerance (±20 μm) between...
