Abstract
An array of movable reflective elements provides wavelength independent performance in spectral equalizers and other optical devices. Each movable reflective element comprises a reflective plate that is suspended by rod-like supports that have a width of less than 2 microns and as small as about 0.25 to 0.35 microns. Semiconductor processing techniques are used to form the rod-like supports. An improved spectral equalizer incorporates the array of movable reflective elements, a controller, collimating/focusing optics and a diffraction element that optically communicate in a free-space optics arrangement.
