Abstract

We present a method for the design and fabrication of InP-based free-standing microelectromechanical systems structures, which include microcantilever beams and Fabry–Perot membranes. The membrane is designed to satisfy both mechanical and optical requirements for a wavelength division multiplexing device and micro-Raman spectroscopy technique is used to evaluate surface stresses. The membrane profile is measured using a white-light interferometry technique, and the effect of the structure geometry on residual stress formation is discussed. From the results obtained, we propose a novel filter design that shows minimum surface profile deviation and stresses.
