Abstract :
We demonstrate the athermal operation and the wavelength tuning of 850nm GaAs-based vertical cavity surface emitting lasers with a thermally actuated cantilever structure. The thermal actuation of a top DBR mirror enables us to compensate the temperature drift of lasing wavelengths. A small temperature dependence of -0.011 nm/K and wavelength tuning of 4 nm were obtained with a newly designed T-shape membrane structure at the same time.
