Abstract :
A widely tunable optical decision scheme using a monolithically integrated semiconductor optical amplifier-sampled-grating distributed Bragg reflector laser diode is proposed. Wavelength tunable optical decision is realized for both the cases of input wavelength detuning and output wavelength detuning. Within an input wavelength detuning range of 28 nm, or within an output wavelength detuning range of 24 nm, a maximum ON/OFF static contrast ratio of 42 dB over a 5-dB input power change is obtained. Dynamic performance up to 10 Gb/s is also demonstrated though numerical simulation using this scheme.
