Abstract: A dynamic gain equalizer-monitor (DGEM) includes a light modulator operable to modulate one or more component wavelengths of an input optical signal. The DGEM also includes a grating operable to receive one or more modulated component wavelengths from the light modulator. The grating is also operable to combine a first portion of each of the one or more modulated component wavelengths and transmit that first portion into an output optical signal. The DGEM may also include a detector array operable to receive, from the grating, a second portion of modulated component wavelengths that are separated from the first portion by the grating. The detector array is operable to generate an electrical signal proportional to an optical characteristic associated with each of the modulated component wavelengths of the second portion.

Abstract: A system and method for packaging multiple MEMS devices is disclosed. A preferred embodiment comprises two or more MEMS devices, such as DMD devices, packaged together into a single package. The MEMS devices can be either on a single substrate or else on multiple substrates, and may be aligned together or not aligned together depending upon the desired orientation of the MEMS devices.

Abstract: A system and method for the modulation of light propagating along an optical path, for example the optical path in a projection display system. As light in the optical path travels from a light source to a display screen, it is shaped and modulated by the various components of the optical path so that the intended visual image appears on the display screen. In accordance with the present invention, a mirror disposed proximate the optical path is operable to be selectively inserted and removed from the optical path to alternately direct the light from one portion of the optical path to another, or to a light dump where it can be absorbed such that the associated heat energy may be properly dissipated. In a preferred embodiment, the mirror is a fold mirror mounted at a stop of the system to fold the light beam approximately 90 degrees when the mirror is inserted in the optical path.
