H. Saito et al., UNIFORM CW OPERATION OF MULTIPLE-WAVELENGTH VERTICAL-CAVITY SURFACE-EMITTING LASERS FABRICATED BY MASK MOLECULAR-BEAM EPITAXY, IEEE photonics technology letters, 8(9), 1996, pp. 1118-1120
Monolithically integrated four-wavelength vertical-cavity surface-emit
ting laser arrays are fabricated by mask molecular beam epitaxy. The l
asing wavelengths are spaced by 5 nm, and their standard deviation for
10 x 12 VCSEL's ranges from 0.27-0.38 mm. Uniform threshold current a
nd 1.5-mW light output are achieved under continuous wave conditions.
