Abstract: An apparatus (2) can comprise an optical slab (4) comprising a rigid substrate of substantially transmissive material. The apparatus (2) can also comprise a WDM multiplexer (6) to receive and combine a plurality of optical signals (14, 16 and 20) at different wavelengths to form a combined optical signal (24) in the optical slab (4) having an aggregate power. The apparatus can further comprise a broadcaster (28) to distribute the combined optical signal (24) from the optical slab (4) to each of a plurality of different optical receivers (30, 32 and 34) with a fraction of the aggregate power of the combined optical signal (24).

Abstract: Coupling modulation of an optical resonator employs a variable modal index to provide modulation of optical signal coupling. A coupling-modulated optical resonator includes an optical resonator having a coupled portion and a bus waveguide having a modulation section adjacent to and coextensive with and separated by a gap from the coupled portion. The modulation section is to modulate coupling of an optical signal between the optical resonator and the bus waveguide according to a variable difference between a modal index of the bus waveguide modulation section and a modal index of the optical resonator coupled portion.

Abstract: A high contrast grating optical modulation includes an optical modulator at a front surface of a substrate to modulate received light. The high contrast grating optical modulation further includes a high contrast grating (HCG) lens adjacent to a back surface of the substrate opposite to the front surface to focus incident light onto the optical modulator. The substrate is transparent to operational wavelengths of the focused incident light and the modulated light.

Abstract: A high contrast grating optoelectronic apparatus includes an optoelectronic device at a front surface of a substrate. The optoelectronic device is to one or both of emit light and detect light through a back surface of the substrate opposite the front surface. A high contrast grating (HCG) lens is adjacent to and spaced apart from the back surface of the substrate by a spacer. The spacer includes one or both of a wafer-bonded substrate and a cavity. The HCG lens is to focus the light.

Abstract: Compact photonics platforms and methods of forming the same are provided. An example of a compact photonics platform includes a layered structure having an active region along a longitudinal axis, a facet having an angle no less than a critical angle formed at at least one longitudinal end of the active region, and a waveguide having at least one grating coupler positioned in alignment with the angled facet to couple light out to or in from the waveguide.

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.
