BPN332: Monolithic micromirror array for single-chip MEMS-based dense wavelength division multiplexed (DWDM) crossconnect

The new goal of this project is to develop a micromirror array, which can be integrated into monolithic 1xN wavelength-selective switch (WSS) and NxN wavelength-selective cross connect (WSXC) for dense wavelength division multiplexed (DWDM) network. The 0.8nm channel spacing of DWDM network requires a forty- element micromirror array with a pitch of 75�m for independent spatial switching of incoming wavelength channels among output waveguides. For integration into a 1x4 WSS and 4x4 WSXC, the micromirror requires a maximum mechanical scan angle of 9.2�.
