Abstract

Pitch-variable gratings with blazed surface profiles are designed and fabricated by combining silicon-on-insulator (SOI) technology with microelectronicmechanical system (MEMS) technology. A two-mask process is employed to realize 4-level blazed surface profile, and electrostatic combdrive microactuators are used to stretch the freestanding grating beams. The experimental results indicate the fabricated 4-level blazed gratings could realize large tuning range and achieve high diffraction efficiency.
