Researchers describe new microcomb lasers they have developed that overcome previous limitations and feature a simple design that could open the door to a broad range of uses.
Light measurement devices called optical frequency combs have revolutionized metrology, spectroscopy, atomic clocks, and other applications. Yet challenges with developing frequency comb generators at a microchip scale have limited their use in everyday technologies such as handheld electronics.
According to Jingwei Ling, an electrical and computer engineering PhD student in Lin's lab and the lead author of the paper, previous approaches usually rely on a single-wavelength laser injected into a nonlinear converter that can transfer the single wavelength into multiple wavelengths, forming the optical comb.
The simplicity of the"all in one" microcomb laser results in lower power demands, lower costs, high tunability, and a turnkey operation. Hurdles remain for implementing these microcomb lasers, particularly with developing fabrication techniques to create such tiny components within the tolerances necessary for manufacturing. But the researchers are hopeful that their devices can be used for applications such as telecommunications systems and light detection and ranging for autonomous vehicles.Jingwei Ling, Zhengdong Gao, Shixin Xue, Qili Hu, Mingxiao Li, Kaibo Zhang, Usman A.
