Modulation-Current Set. The resistor at
MODSET programs the temperature-stable
component of the laser modulation current.
Temperature-Compensation Set. The resistor
at TC programs the temperature-increasing
component of the laser modulation current.
Ground. This must be soldered to the circuit
board ground for proper thermal
performance. See Layout Considerations.
