摘要： A planar hybrid optical amplifier is fabricated on a single crystal substrate. The components that are common to a variety of optical amplifier circuits are mounted on the substrate and the planar device that results is readily interchanged in various applications. In one embodiment the multiplexed signal consisting of light from a pump laser and an optical signal are introduced into a rare earth doped fiber which amplifies the input signal through stimulated emission of radiation.

摘要： The non-blocking micro-optic switch matrix (NMSM) includes a plurality of optical routing elements (OREs) forming an M×N matrix. Each ORE of the plurality includes a first and second wafer prism having a gap disposed therebetween. A body of transparent solid material disposed in the gap has a contracted state at a first temperature and an expanded state at a second temperature. The contracted state defines an air gap in the path of light traveling along a first axis, causing light to be deflected along a second axis through total internal reflection. The first and second axes are at a non-zero angle with respect to one another. The expanded state of the transparent material removes the air gap disposed in the path of light traveling along the first axis allowing light to pass through the first wafer prism, through the body of transparent material and into the second wafer prism.

摘要： A configurable wavelength multiplexing device having first, second, and third reflectors. The first reflector has a first state in which it transmits incoming light (having first and second wavelengths) along a first transmitted path and a second state in which it reflects the light along a first reflected path. The second reflector reflects the first wavelength and transmits the second wavelength. The third reflector reflects the first wavelength. The first, second, and third reflectors are oriented so that when the incoming light is transmitted along the first transmitted path, the first wavelength is reflected by the second and third reflectors to travel along second and third reflected paths, the third reflected path intersects the first reflector at an angle such that the first wavelength is transmitted by the first reflector and continues on the first reflected path, and the second wavelength is transmitted by the second reflector.
