In highspeed optical communication systems, the laser diode and modulator driver is one of the key components in the transmitter, where it performs the interface between laser d.c. bias. This feedback control circuit was designed for use with the laser drive circuit shown in Fig. 3.67 to give digital operation at high bit rates (in the GHz range). The block diagram of the device is illustrated in Fig. 3.71.

A schematic laser diode circuit with bipolar transistors is shown in Fig. 11.1.A laser diode collimator, with a numerical aperture of 0.5, was used to collect the light from the diode. The collimator output was then fed into a 6:1 beam expander, with focusing capabilities, and transmitted down range. extended source along the slow axis A beam footprint diagram was used to estimate the geometrical illumination pattem on the target at a known distance This section discusses the design of the llT driver circuit and the net performance of the [IT as a demodulator.Figure 7 presents most basic laser drive circuit
