摘要
A linear dense-packed spatial light modulator (LDSLM) and method of modulating light using the same are provided. In one embodiment, the LDSLM comprises a plurality of two dimensional (2D) modulators grouped proximal to one another on a surface of a substrate to form a densely-packed, linear array having a plurality of pixels along a longitudinal axis of the array. Each pixel includes a number of 2D modulators electrically coupled to receive a common drive signal and to modulate light reflected therefrom in response to the drive signal. Preferably, each pixel includes at least two 2D modulators grouped along a transverse axis of the array. More preferably, the number of 2D modulators along the transverse axis in each pixel is selected to provide a desired power density while avoiding an undesired thermal gradient across the LDSLM. The LDSLM and method are particularly useful in printing applications. Other embodiments are also disclosed.
