I will build frequency combs integrated on optical chips that can be mass-manufactured with CMOS technology. Unlike the current chip scale Kerr comb based solutions, they do not need to be optically pumped with a powerful continuous wave laser and can have much narrower comb spacings. The challenge here is two-fold. First, we need to make electrically powered integrated low noise oscillators. Second, we need to lower the threshold of current on-chip nonlinear optical interactions by an order of magnitude to use them in on-chip OFC generators.
