Abstract :
The effective threshold for stimulated Brillouin scattering for a data-encoded signal is increased from 11.0 to 23.4 dBm by using a temperature-tunable laser diode. A 5 kHz sinusoid is applied to a Ti/Pt thin film resistor located along the laser contact on top of the device, resulting in a 10 kHz dithering of the wavelength. The residual amplitude modulation index at 10 kHz is only 1.2×10-4
