Abstract :
Two types of expanded semiconductor optical amplifier gate switches (front 3/spl times/4 to 32/spl times/32) are analyzed numerically with respect to input power dynamic ranges. The dependences of the dynamic range on switch size, amplifier placement, and gain are studied. It is concluded that a large integrated switch is preferred over a large switch constructed from fiber-optic couplers and integrated 4/spl times/4 switches.
