Abstract :
Radio frequency modulation of a multicavity laser diode may be used to precisely select lasing optical wavelength for wavelength-division multiplexing (WDM) systems. We demonstrate gigabits-per-second in-band digital data transmission with a low bit-error ratio (BER) and out-of-band radio frequency wavelength selection with -30-dB wavelength selectivity. The same device may also be used to transmit wavelength encoded digital data.
