Abstract :
A technique using two thermistors for maintaining junction temperature of a laser diode over a wide current range is proposed. The wavelength of a 980 nm module was stabilised within 1 nm with this technique from 25 to 400 mA. compared to a wavelength shift of 5 nm with traditional one-thermistor control.
