WebNew applications that are extremely sensitive to relative signal latency, high frequency trading for example, require length equalized optical interconnects accurate to ±0.25%of total cable length. WebAbstract: We report on a study of hyper-parametric oscillation in high-Q calcium fluoride and magnesium fluoride optical microresonators, and show that, magnesium fluoride microresonators generate wider Raman-free Kerr frequency combs at telecom wavelengths, in contrast with calcium fluoride ones.
