| Abstract(in English) | We propose a micromachined vertical cavity resonator enabling temperature insensitive operation for surface emitting lasers or optical add/drop filters. The strain-induced displacement from differential thermal expansion is used to compensate the wavelength shift caused by temperature variation. Also, a wavelength trimming technology is suggested by using the same principle with a precise control in strain. A possibility of drastic reduction in temperature sensitivity of wavelength as well as precise wavelength adjustment is presented. We fabricated a micromachined vertical cavity filter with a GaAlAs/GaAs DBR, which is mechanically tuned by differential thermal expansion. We observed a large negative temperature coefficient of resonant wavelength. It is shown that its temperature dependence can be widely controlled by the proposed concept. A possibility of temperature insensitive operation is discussed In addition, a preliminary experiment on wavelength trimming will be also presented. |
