| Abstract(in English) | In this paper, we propose and demonstrate micromachined InP vertical cavity surface emitting lasers (InP VCSELs) and resonant-cavity photodetectors with a thermal strain control layer for temperature insensitive operations. The thermal strain control layer is employed on the cantilever so that an increase in temperature moves 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. Using such a 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 0.04nm/K and 0.031nm/K for micromachined InP VCSELs and photodetectors with an 85-μm long cantilever, which is almost three-times less than that of ～0.1nm/K for typical semiconductor lasers. |
