Attosecond pulse generation using the multistage nonlinear microring resonators

Abstract

We propose a new system of an attosecond pulse generation by using the integrated nonlinear microring devices. A. soliton light pulse with wavelength of 1550 nm is entered into the multistage microring resonators, where the ring radii of the recent integrated device product are within the range from 5 to 10 microns. Results obtained have shown that the ultrashort pulse width in the attoscale regime and beyond can be easily generated. When the input peak power of 12 W is applied into the system, the generated pulse with pulse width of 50 is achieved. © 2008 Wiley Periodicals, Inc.
