In this paper, we propose and demonstrate micromachined InP vertical cavity surface emitting lasers (InP VCSELs) and resonant-cavity photodetectors with an InP-based thermally strained layer for temperature insensitive operation. The thermally strained layer is employed on the cantilever in such a way that an increase in temperature displaces the cantilever downward resulting in a blue wavelength shift which is against with the red wavelength shift caused by the temperature effect in semiconductor materials. Furthermore, with the bimorph effect the temperature dependence can be freely controlled in a micromachined cantilever structure, avoiding the use of a temperature controller. From experiments, we obtain temperature dependences of 0.04 nm/K and 0.031 nm/K for micromachined InP VCSELs and photodetectors with an 85-um long cantilever, which is almost three-times less than that of ~0.1 nm/K for typical semiconductor lasers. |
