Paper Abstract

Frequency combs, analogue to digital sampling, and free space optical communications are emerging applications that can benefit from advances in elegant, compact, and high-performance miniature mode-locked lasers. By virtue of their ‘chip-scale’, and multiplicity of adjacent waveguides, compact planar waveguide devices are suited to efficiently operate in the ~0.5 GHz to 10 GHz pulse regimes, and to have key advantages when employed as dual-frequency combs. The erbium ytterbium cerium co-doped ZBLAN chips we have developed have achieved transform limited mode-locked output near 1.55 μm, pulse lengths down to 180 fs, and operation up to 5 GHz. This paper will also cover our more recent work on demonstrating a dual-frequency comb based on simultaneously mode-locking adjacent waveguide lasers in a common-cavity setup and demonstrate its spectroscopic potential by rapidly (~ms) acquiring high resolution and broad (<2 THz) molecular spectra of molecules.
