Figure 5: Circuit example for M-type laser diodes
Althought this type of laser diode are supported by iC-
NZN, it’s strongly recommended to use iC-NZP instead
since in this configuration, all the pulses at LDK will be
coupled directly to pin MD due to monitor diode’s in-
ternal capacitance, thus making an accurate control
much more difficult. Moreover, applications with M-
type laser diode case grounded are possible with iC-
NZP only.
