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: Vertical-cavity surface-emitting lasers (“VCSELs”) and VCSEL arrays are disclosed. In one aspect, a surface-emitting laser includes a grating layer having a sub-wavelength grating to form a resonant cavity with a reflective layer for a wavelength of light to be emitted from a light-emitting layer and an aperture layer disposed within the resonant cavity. The VCSEL includes a charge carrier transport layer disposed between the grating layer and the light-emitting layer. The transport layer has a gap adjacent to the sub-wavelength grating and a spacer region between the gap and the light-emitting layer. The spacer region and gap are dimensioned to be substantially transparent to the wavelength. The aperture layer directs charge carriers to enter a region of the light-emitting layer adjacent to an aperture in the aperture layer and the aperture confines optical modes to be emitted from the light-emitting layer.
