摘要： A Fabry-Perot optical switch includes a saturable absorber surrounded by a pair of mirrors. Coupled to the saturable absorber is an input waveguide, an output waveguide, and a control beam waveguide. In the absence of light input to the control beam waveguide, the saturable absorber prevents an input signal on the input waveguide from passing through and being output on the output waveguide, thus placing the switch in an “off” state. In the presence of light input to the control beam waveguide and incident on the saturable absorber, the saturable absorber allows the input signal to pass through and be output on the output waveguide, or be reflected and output on the output waveguide, thus placing the switch in an “on” state.

摘要： An optical filter that includes a resonator cavity comprised of a saturable absorber material is provided. An input signal waveguide, a non-resonant wavelengths output waveguide, and a resonant wavelength output waveguide are coupled to the cavity. A refractive index of the saturable absorber material is altered so that a resonant wavelength output is directed down the resonant wavelength output waveguide and non-resonant wavelengths are directed down the non-resonant wavelengths output waveguide.

摘要： A display device that includes an underlying excitation source, a converting layer, and an optical filter layer. The underlying excitation source emits light in a spatial pattern that may or may not be altered in time and has a short wavelength capable of being at least partially absorbed by the overlying converting layer. The converting layer can be a contiguous film or pixels of quantum dots that can be dispersed in a matrix material. This converting layer is capable of absorbing at least a portion of the wavelength(s) of the light from the underlying excitation source and emitting light at one or more different wavelengths. The optical filter layer prevents the residual light from the excitation source that was not absorbed by the converting layer from being emitted by the display device.

摘要： A laser gain medium. The novel laser gain medium includes a host material, a plurality of quantum dots dispersed throughout the host material, and a plurality of laser active ions surrounding each of the quantum dots. The laser active ions are disposed in close proximity to the quantum dots such that energy absorbed by the quantum dots is non-radiatively transferred to the ions via a Forster resonant energy transfer, thereby exciting the ions to produce laser output. In an illustrative embodiment, each quantum dot is surrounded by an external shell doped with the laser active ions.
