Abstract: A system can include an optical multiplexer to combine a plurality of optical input signals having respective wavelengths into a wide-channel optical input signal that is provided to an input channel. The system also includes a photonic packet switch comprising a switch core and a plurality of ports defining a switch radix of the photonic packet switch. The input channel and an output channel can be associated with one of the plurality of ports. The photonic packet switch can process the wide-channel optical input signal and can generate a wide-channel optical output signal that is provided to the output channel. The system further includes an optical demultiplexer to separate the wide-channel optical output signal into a plurality of optical output signals having respective wavelengths. The optical multiplexer and the optical demultiplexer can collectively provide the system with a radix greater than the switch radix.

Abstract: Various embodiments of the present invention are directed to surface-emitting lasers with the cavity including at least one single-layer, non-periodic, sub-wavelength grating. In one embodiment, a surface-emitting laser comprises a grating layer configured with a non-periodic, sub-wavelength grating, a reflective layer, and a light-emitting layer disposed between the grating layer and the reflector. The non-periodic, sub-wavelength grating is configured with a grating pattern that controls the shape of one or more internal cavity modes, and controls the shape of one or more external transverse modes emitted from the surface-emitting laser.

Abstract: Various embodiments of the present invention are directed to optical devices comprising planar lenses. In one aspect, an optical device includes two or more planar lenses, and one or more dielectric layers. Each planar lens includes a non-periodic, sub-wavelength grating layer, and each dielectric layer is disposed adjacent to at least one planar lens to form a solid structure. The two or more planar lenses are substantially parallel and arranged to have a common optical axis so that light transmitted through the optical device substantially parallel to the optical axis is refracted by the two or more planar lenses.
