摘要： The antiresonant waveguide apparatus is for periodically selecting a first series of at least one optical wavelength from a first incoming light signal. It comprises a first waveguide having an input for receiving the incoming light signal, the first waveguide having guiding mirrors for guiding the incoming light signal, one of the guiding mirrors being a first partial reflectivity mirror; a second waveguide having guiding mirrors for guiding an outputting light signal containing the first series of at least one wavelength; and a first Fabry-Perot resonator adjacent to the first partial reflectivity mirror, and forming one of the guiding mirrors of the second waveguide. The Fabry-Perot resonator is a second partial reflectivity mirror for the second waveguide. The Fabry-Perot resonator has a predetermined thickness determining the first series of at least one optical wavelength transmitted through the Fabry-Perot resonator from the first waveguide to the second waveguide.

摘要： A communications switch for switching telecommunications signals from input wavelength division multiplexed (WDM) optical fibers to output WDM optical fibers is disclosed. A two-dimensional optoelectronic switch is also described which uses tunable lasers and optical diffractive elements to switch a matrix of input/output gigabaud channels without blocking. As the channels proceed through the switch they are spatially switched among one another first within rows, then within columns, and then again within rows in the matrix. The two-dimensional optoelectronic tune-switch (2DOTS) can realize the functionality of the nonblocking three-stage Clos switch for input/output ports carrying several gigabit/s data streams.

摘要： Tunable laser radiation is obtained by pumping a wedge-shaped ultra-short laser cavity with picosecond excitation pulses. Continuous tuning of the laser is achieved by translating either the wedge-shaped laser cavity or the excitation pulses so that different volumes of the laser material are exposed to the excitation pulses. In one embodiment utilizing picosecond laser excitation pulses the wedge-shaped laser cavity is a slightly wedged film of GaAs coated on both sides with dielectric mirrors.
