System and method for generating optical return-to-zero signals with alternating bi-phase shift and frequency chirp

A system for generating an optical return-to-zero signal, the system comprising:

• a bit separator configured to receive an electrical non-return-to-zero signal and generate a first input signal and a second input signal;
• a first driver configured to receive the first input signal and generate a first driving signal, the first driving signal being proportional to the first input signal in signal strength;
• a second driver configured to receive the second input signal and generate a second driving signal, the second driving signal being proportional to the second input signal in signal strength;
• a light source configured to generate a light;
• an electro-optical modulator configured to receive the light, the first driving signal, and the second driving signal, modulate the light with the first driving signal and the second driving signal, and generate an optical signal;
• wherein:
• the electrical non-return-to-zero signal includes a first plurality of bits and a second plurality of bits;
• the first driving signal includes a third plurality of bits, the third plurality of bits equal to the first plurality of bits multiplied by a first negative number in signal strength;
• the second driving signal includes a fourth plurality of bits, the fourth plurality of bits equal to the second plurality of bits multiplied by a second negative number in signal strength;
• the optical signal is an optical chirped return-to-zero signal.
