Broadband, flat frequency comb generated using pulse shaping-assisted nonlinear spectral broadening

The comb was generated using nonlinear spectral broadening on a mode-locked laser (MLL), assisted by adaptive pulse shaping. A linear pulse shaping element, which was dynamically controlled by an adaptive algorithm exploiting the covariance matrix adaptation evolution strategy (CMA-ES), was placed prior to a nonlinear element. A 3-dB bandwidth of 35nm was achieved, and the power variations about a central region of 30nm were less than 1dB.

Abstract

In this paper we demonstrate the nonlinear generation of a low noise, ultra-flat frequency comb covering the full C-band. The comb was generated using nonlinear spectral broadening on a mode-locked laser (MLL), assisted by adaptive pulse shaping. A linear pulse shaping element, which was dynamically controlled by an adaptive algorithm exploiting the covariance matrix adaptation evolution strategy (CMA-ES), was placed prior to a nonlinear element. A 3-dB bandwidth of 35nm was achieved, and the power variations about a central region of 30nm were less than 1dB.
