Driving a butterfly package DFB laser
I have found an application note on Current Sources for Fiber Optic Lasers, Application Note 90 by Jim Williams of LTC.

The Grounded Anode Current Source circuit is suitable to drive my laser. The circuit also has current limiting, over-voltage protection, and self enable (for slow start). And I have designed a circuit using MAX1979 to control the internal TEC temperature. These two should ensure proper current and temperature control required for the safe operation of my laser.
