Patent ID: 7742705

Claim:
A system for providing chirped light for an optical network, the system comprising: a light source configured to provide a light; a driving signal source configured to provide a first driving signal, wherein the first driving signal does not include information associated with data; an amplifier configured to receive the first driving signal, amplify the first driving signal, and provide a second driving signal at a predetermined amplification level, the second driving signal being the amplified first signal; a splitter configured to receive the second driving signal and split the second driving signal into a third driving signal and a fourth driving signal; a first attenuator configured to receive the third driving signal, attenuate the third driving signal at a first attenuation level, and provide a fifth driving signal, the fifth driving signal being the third driving signal attenuated by the first attenuator; a second attenuator configured to receive the fourth driving signal, attenuate the fourth driving signal at a second attenuation level, and provide a sixth driving signal, the sixth driving signal being the fourth driving signal attenuated by the second attenuator; a voltage source configured to provide a first bias voltage and a second bias voltage; a modulator configured to receive the light, modulate the light using a first applied voltage and a second applied voltage, and provide a chirped light output; wherein the first attenuation level is different from the second attenuation level; wherein the fifth driving signal is different from the sixth driving signal; wherein the first applied voltage includes the fifth driving signal and the first bias voltage; wherein the second applied voltage includes the sixth driving signal and the second bias voltage.
