Wavelength- and time-s elective all-optical channel dropping in periodically poled Ti: LiNbO3 channel waveguides

Abstract

The wavelength- and time-selective all-optical channel dropping in periodically poled Ti:LiNbO3 channel waveguides was discussed. Individual 10-GHz channels were selectively dropped with an extinction ratio of -15 dB using 100 mW of average pump power. Results showed that the difference between required pump power levels for optimum signal depletion of CW and pulsed interaction was due to group velocity mismatch between the interacting waves.
