Passive Grating Modulator
These modulators operate at ultrahigh frequencies in the hundred kHz range, and their micromirror-free configuration simplifies the fabrication process and reduces costs compared to micromirror-based modulators. However, these modulators are limited in their optical. This Micro-Electro-Mechanical (MEMS) Grating Modulator, manufactured by our strategic partner Boston Micromachines Corporation, has controllable groove depth which modulates intensity. The operating principle of the GLM is introduced in this paper. 1 Introduction to Grating Light Modulators In Chapter 9 we described the optical properties of mirror arrays and demonstrated that phase modulation is preferable to amplitude modulation for many applica- tions. This grating-assisted Michelson (GAMI) modulator can operate as either an intensity or amplitude. Microelectromechanical system (MEMS) grating modulators enable versatile beam steering functions through the electrostatic actuation of movable ribbons.

Multi-quantum-well spatial light modulator
A multiple quantum well spatial light modulator combines both optically addressed and electrically addressed portions on a single wafer. We present results obtained with a single-pixel amplitude modulator. This SLM will run at 10 kHz and have one. The Fraunhofer Institute for Photonic Microsystems IPMS and the Max Planck Institute of Quantum Optics (MPQ) have achieved significant results in generating arbitrary light distributions, which are also relevant to atomic quantum computing. Concept makes two-dimensional SLM arrays by taking. S. One ofthe most useful is a large electroabsorption effect which can be utilized to make optical intensity modulatorsl.
