Reconfigurable Photonic Switch Based on a Binary System Using the White Cell and Micromirror Arrays
We describe an optical switch for use in crossconnects. It is a free-space device, based on multiple bounces in a pair of White cells sharing a spatial light modulator at one end. In a companion paper, we described various polynomial cells, in which the number of outputs was proportional to the number of bounces raised to some power. In the binary device described here, the number of possible o...
متن کاملOn-chip optical processing
Microoptical components, such as diffractive and refractive microlenses, micromirrors, beam splitter and beam combining have recently received considerable attention in the optics R&D centers and finally in the manufacturing community. This achievement is due to MEM technology that demonstrated major improvements in overall performance/cost of optical systems while offering the possibility of r...
متن کاملFabrication of micro-optical switch by post-CMOS micromachining process
This work presents the micro-machined 2-D switch array for use on free-space optical interconnect platform integrated with a digital 1×8 de-multiplexer control circuit together. Moreover, this device employs electrostatic actuation for light beam directions control. The CMOS-MEMS array-based optical platform contains 10×10 circular micromirrors switching spots, the diameter of each mirror is ab...
متن کاملExperimental generation of an optical field with arbitrary spatial coherence properties
We describe an experimental technique for generating a quasi-monochromatic field with any arbitrary spatial coherence properties that can be described by the cross-spectral density function, W r1; r2 . This is done by using a dynamic binary amplitude grating generated by a digital micromirror device to rapidly alternate between a set of coherent fields, creating an incoherent mix of modes that ...
متن کاملFabrication of a Micromirror with Sidewall Electrodes
We designed and fabricated a micromirror with sidewall electrodes in the Cornell NanoScale Science & Technology Facility (CNF) for endoscopic application. The micromirror can perform 2-dimensional scanning. The static and dynamic performances of the micromirror are improved over that of a micromirror without sidewall electrodes. In addition, undesired spring-softening effect that is commonly fo...
