Abstract

Optical signal processing requires spatial as well as temporal dimensionality. Large guided-wave modulator arrays can provide this capability with total control of both parameters and with very high speed. These devices may be used for such operations as correlations, complex transformations, and matrix-vector computations. Reported here is the demonstration of a ten-channel modulator array. Parabolic horn couplers are used on each input channel for increased gain. Compact and efficient mode extinction modulators provide linear response. Fabrication considerations including the use of isolation channels to reduce crosstalk are also reported.
