Data travels through thousands of miles of fiber optic cables underneath the world’s oceans—via pulses of light. And according to experts, the data in these cables is at great risk of being intercepted. However, a newly designed frequency comb—recently developed by researchers at the USC Viterbi School of Engineering might be an effective tool for data encryption.
Scientists have invented a new method to create a frequency comb—a tool that increases the potential applications of lasers by converting a single wavelength into multiple wavelengths, effectively creating tens to hundreds of lasers from a single laser. The new frequency comb is the size of a human hair compared with traditional frequency combs that can be as large as an apartment refrigerator. More importantly, the newly generated comb requires 1000x less power to operate, allowing for mobile applications.
