...ely and continuously wavelength-tunable single-mode laser diodes in the 750-2100 nm wavelength range will be developed. The underlying VCSEL structure is completed by a micro-machined moveable Bragg-mirror with a sub-wavelength grating (SWG). The single-mode property of the VCSEL structure is thus ideally combined with the polarization stability of the SWG and the wide and continuous tunability of ...
