Impedance matching circuit for optical transmitter

A system comprising:

• a network device comprising a DRAM memory;
• and
• an optical transmitter coupled with the network device, the optical transmitter including an impedance matching circuit including:
• an equalizer circuit coupled in series with a driver of an electro-absorption modulator to receive a signal therefrom and coupled in series with the electro-absorption modulator to provide a signal thereto;
• and
• a resistor coupled between the equalizer circuit and ground and coupled in parallel with the electro-absorption modulator.

A method comprising:

• forming an equalizer circuit on a circuit board;
• printing a resistor that is coupled between the equalizer circuit and ground on the circuit board;
• and
• coupling a driver of an electro-absorption modulator in series with the equalizer circuit by mounting the driver on the printed circuit board.

A method comprising:

• providing a signal to an equalizer circuit of an impedance matching circuit;
• receiving a portion of the signal from the equalizer circuit at a resistor of the impedance matching circuit that is coupled between the equalizer circuit and ground;
• receiving a portion of the signal at an electro-absorption modulator that is coupled in series with the equalizer circuit and coupled in parallel with the resistor;
• and
• modulating light with the electro-absorption modulator based at least in part on the received portion of the signal.
