ABSTRACT:
The laser diode modulator disclosed herein employs a series of field-effect transistors provided with an input circuit utilizing a succession of inductive elements arranged to form a lumped element transmission line of essentially constant characteristic impedance. The drain or output terminals of the transistors drive an output circuit employing a series of inductive elements which, together with shunt capacitors, form a singly terminated filter providing a graduated and decreasing characteristic impedance. The laser diode is connected as the termination of the filter.
