Abstract

We describe a single polarization, non-blocking 4x4 Ti:LiNbO₃ optical switch array with very low single switch crosstalk (≤ - 35dB). The inputs to one of the several devices made have been permanently attached to four laser transmitters using polarization maintaining fiber. For this purpose, an array of four fibers was assembled using specially designed silicon grooves and externally keyed polarization maintaining fiber¹. The polarization maintaining fiber was lensed and aligned to the laser in a standard package.
