Laser Drivers Directly modulated lasers are most naturally driven by current sources because the optical signal above threshold is ... The diode and circuitry typically has a rather long response time and so measures the average power produced by the laser. ... Most are implemented by use of feedback control based on some combination of the measurement of the electrical data mark density, the peakanbsp;...
