Abstract
Arrays of blocking optical switches formed from optically amplifying waveguides are used to transmit or block one or more input beams to one or more selected optical channels. Passive optical waveguides couple the optical input to the amplifying waveguides. Optical splitters monolithically formed with passive optical waveguides are used to route the optical signal from a single fiber to the array of amplifying waveguides.
