20MHz VCSEL 3mW LASER TEST CIRCUIT - June 17, 2000


This circuit takes advantage of some new vertical cavity surface emitting lasers (VCSEL) that donít require light output control circuits. The circuit shows how to drive the device from a single high speed CMOS IC. The circuit can easily be modified to transmit signals from kilohertz to about 50MHz.
