More Efficient On-Chip Laser Frequency Comb (Harvard)

popularity

A new technical paper titled “High-efficiency and broadband on-chip electro-optic frequency comb generators” was published by researchers at Harvard, Stanford, Caltech, and Hyperlight.

The research claims the electro-optic frequency device is 100% more efficient and has 2X the bandwidth of previous technology.    According to Harvard’s news release, “the latest research applies the two concepts to address the challenge in resonator based electro-optic frequency combs – efficiency-bandwidth tradeoff.” ” We demonstrated that by combining these two approaches — the coupled resonator with the electro-optical frequency comb — we could improve the efficiency a lot without sacrificing bandwidth. In fact, we actually improved bandwidth,” said Yaowen Hu, a research assistant at SEAS and first author of the paper.
