Abstract
Methods and devices for controlling an optical device. In one embodiment, the optical device is directly controlled by an outside analog electrical signal. Depending on the voltage or current level of the electrical signal, the output of the optical device is changed accordingly. An operational amplifier may be used to amplify the analog electrical signal prior to the signal being received by the circuitry of the optical device. For maximum flexibility in control, a switch can be coupled to the operational amplifier so that either analog or digital control signals can be used.
