✦ Synopsis

On-the-fly all-optical header processing and control signal generation were simultaneously realized using a dualwavelength injection-locked Fabry-Pe ´rot laser diode. The special two-level input control signal was generated by direct modulation of a distributed feedback laser. The header processing rate is 2.5 Gb/s, the payload data rate is 10 Gb/s, and the packet length is 25.6 ns. The switching ratio for the switched control signals measured spectrally was improved from 3 dB to over 20 dB by using a polarizer.

## Abstract We proposed and experimentally demonstrated a novel method of optical mm‐wave generation using only one Mach‐Zehnder modulator and a direct‐modulator, based on the method of optical carrier suppression. Using this proposed method, the 2.5 Gb/s data channel was successfully transmitted o
