Abstract :
Polarization self-modulation achieved at frequencies far above the relaxation oscillation frequency in an external-cavity hybrid ring semiconductor laser without the need for any high-speed electronics is discussed. This demonstrates that polarization modulation may be a viable alternative for generating controlled signals at extremely high frequencies ( approximately=100 GHz) for use as microwave and millimeter-wave optical carriers.<>
