Dual-mode laser diode transmitter |
摘要 |
A semiconductor injection laser diode is coupled via a switch to two drivers. One driver provides a drive current above the threshold current required to cause the injection laser diode to lase. The other driver provides a drive current below this threshold current, causing the laser diode to operate in a light-emitting diode (LED) mode. The switch couples the laser diode to one or the other of the drivers depending upon the receiver to which the transmitter is coupled.
