Abstract
The behaviour of laser diode in the vicinity of the lasing threshold
was investigated using numerical methods. Polynomial equations were
fitted to the electro-optical characteristics of the laser and the
temperature variation of the coefficients of these fits were related
to temperature dependent parameters of the laser. The approximate
values of the threshold current was also determined from these coefficients.
A novel method of presenting laser characteristics called Temperaturecurrent
characteristics was further derived from Light-current characteristics
by linear interpolation and approximate values of the temperature
sensitivity of the laser was determined from this characteristics.
