Chip-Based Frequency Combs and Random Number Generators
Not long ago, CMOS-compatible platforms based on Silicon were viewed as undesirable for integrated optics since lasers could not be created from such materials. However, over the past decade silicon has emerged as an exceptional material for manipulating light and has led to realization of ultrahigh-performance photonic devices in fields from data communications to medicine. I will discuss the nonlinear photonics using silicon-based chips with only milliWatt power levels. Such capability can be used to create chip-based optical frequency combs and quantum random number generators that offer a wide range of applications in telecommunications, time and frequency metrology and photonic computing.
