Abstract
As the aperture size of oxide-apertured vertical-cavity surface-emitti ng lasers (VCSEL's) shrinks, the lasing wavelength blueshifts. We have calculated this effect using both a scalar effective index model and a full-vector weighted index model. Results were compared against expe rimental data fbr two different VCSEL designs emitting near 780 and 85 0 nm. We find that the full-vector weighted index calculation matches the data remarkably well, while the scalar effective index calculation underestimates the blueshift.
