Instructions for use – LC25W****B/LC25EW****B
Pin 1 and Pin 2 Thermistor
The thermistor is used in a control loop in conjunction with
the thermo-electric cooler to maintain the laser submount
temperature at the required value for wavelength.
Operating current should be less than 100µA to prevent
self-heating errors.
For Etalon stabilized devices the thermistor is used for the
initial set up of the submount temperature at the required
wavelength value. Operating current should be less than
100 µA to prevent self-heating errors. Once the initial
submount temperature has been achieved control of the TEC
current is handed over to the Etalon locking circuit to achieve
fine tuning.
Pin 3 Laser DC bias (-)
Laser bias current (negative with respect to package ground)
is applied via this pin which forms one side of the bias-T
connection to the laser cathode.
Pin 4 Monitor anodes, Pin 5 Common Monitor cathode
The back facet monitor provides a mean power reference for
the laser and is normally operated with a 5V reverse bias.
For Etalon stabilized devices the monitor diodes are arranged
in the package such that they give an equal monitor current
when the laser wavelength is matched to the ITU grid.
A reverse bias must be applied equally across each of the
monitors, this is commonly achieved by applying 5 V to Pin 5.
Pin 6 TEC (+), Pin 7 TEC (-)
Applying a positive voltage on pin 6 with respect to pin 7 will
cause the internal submount to be cooled relative to the case
temperature. Reversing the polarity will raise the submount
temperature relative to the case. The TEC supply should be
capable of delivering up to 0.9A at 2.4V.
Pin 8, 9, 11, 13 Case ground
These pins must be grounded in all applications.
Pin 10
This pin is not connected for the LC25W product and it
should be grounded if possible. For the Etalon locked
product this pin is used for the monitor long anode.
The monitor diodes are arranged such that they give an equal
monitor current when the laser wavelength is matched to the
ITU grid. A reverse bias must be applied equally across each
of the monitors, this is commonly achieved by applying
5V to pin 5.
Pin 12 Laser modulation (-)
The data input (modulation current) is applied via this pin
which is a nominal 25 Ohm impedance coplanar line.
Pin 14 N/C
This pin is not connected. It should be grounded if possible.
