High‐Efficiency Generation of Flat High‐Order Sidebands in a Gently Modulating Optomechanical System

The high‐order sideband generation in a gently modulating optomechanical system, which consists of a standard optomechanical system driven by a mildly amplitude modulated field (MAMF) is investigated. It is found that the sideband generation can be effectively optimized by choosing an appropriate component number N of the MAMF, and this scheme can generate more and flatter high‐order sidebands with the same input power compared with the conventional model. The efficiency of the sideband generation is much superior to the traditional scheme. The challenge for high‐efficiently realizing a flat optical frequency comb based on optomechanical systems may be aided by this work.
