A card cartridge for shuffling machines has a body and a cover. The body has a longitudinal slot defined in the body in a slantwise manner for receiving cards discharged from the shuffling machine, and at least two stops protrude oppositely from two side edges of the body to define a drawing gap. The cover is mounted detachably on the body and has a tail extending slantwise into the slot and two side panels abutting two side surfaces of the body to ensure the cover is stably positioned on the body. Furthermore, a wedge is movably disposed in the slot, selectively moving toward the second end of the body to press the cards toward the stops. When playing a card game, the body is implemented horizontally and the wedge moves along the slot to press the cards so players can easily draw cards sequentially from the drawing gap.

In a method of amplifying optical input signals over a wide bandwidth, the optical input signals are applied to an optical waveguide made from a rare-earth-doped amorphous material (e.g., erbium-doped yttrium aluminum oxide material).
