Abstract
This paper presents studies of electro-optics and spectral properties of distributed feedback diode lasers emitting at the 940 nm region. The optical power of the lasers reaches 358 mW at 25 °C. The obtained results show that the wavelength shift vs. pumping current is 0.0029 nm/mA and vs. temperature is 0.059 nm/°C. The lasers have a narrow linewidth of kHz. Moreover, the centre of the laser beam is unchanged with the various injection currents.
