Abstract
A fiber optic transmitter having a directly modulated laser diode for transmitting a modulated optical signal, a pin diode for providing a pin diode monitor current representing the output power of the laser diode, an optical power source for receiving an optical signal and providing an electrical signal, a power regulator for providing a laser diode driver current which varies with the pin diode monitor current, an amplifier for receiving an RF signal and providing an amplified RF signal to the laser diode, where the laser diode driver current directly modulates the laser diode and biases the transistor in the amplifier.
