Abstract :
We studied the wavelength tuning properties of an edge emitting extended cavity laser diode with a micromechanical Fabry-Perot interferometer as an external reflector. It was seen that this arrangement provides essentially similar tuning range (few nanometers) as traditional system with one external mirror only, but with a much smaller mirror movement. In this letter, the theoretical model and the characteristics of the tuning are explained.
